Tratamiento conservador para la incontinencia urinaria posterior a la prostatectomía

Contraer todo Desplegar todo

Resumen

Antecedentes

La incontinencia urinaria es común después de una prostatectomía radical y también puede ocurrir en algunas circunstancias después de una resección transuretral de la próstata (RTUP). El tratamiento conservador incluye el entrenamiento muscular del suelo pélvico con o sin biorretroalimentación, la estimulación eléctrica, la inervación magnética extracorpórea (IMEC), el uso de dispositivos de compresión (pinzas peneanas), los cambios en el estilo de vida o una combinación de métodos.

Objetivos

Determinar la efectividad del tratamiento conservador para la incontinencia urinaria hasta 12 meses después de una prostatectomía transuretral, suprapúbica, laparoscópica, radical retropúbica o perineal, incluida cualquier terapia conservadora individual o cualquier combinación de terapias conservadoras.

Métodos de búsqueda

Se realizaron búsquedas en el Registro Especializado del Grupo Cochrane de Incontinencia (Cochrane Incontinence Group) (5 febrero 2014), CENTRAL (2014, número 1), EMBASE (enero 2010 hasta la semana 3 2014), CINAHL (enero 1982 hasta el 18 enero 2014), ClinicalTrials.gov y en la World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (ambas búsquedas se realizaron el 29 enero 2014), y en las listas de referencias de los artículos pertinentes.

Criterios de selección

Ensayos controlados aleatorizados o cuasialeatorizados que evaluaran los efectos de las intervenciones conservadoras para la continencia urinaria en hombres después de realizada una prostatectomía.

Obtención y análisis de los datos

Dos o más autores de la revisión evaluaron la calidad metodológica de los ensayos y extrajeron los datos. Se intentó establecer contacto con varios autores de los estudios incluidos para obtener información adicional.

Resultados principales

Cincuenta ensayos cumplieron los criterios de inclusión, 45 en hombres después de la prostatectomía radical, cuatro ensayos después de la RTUP y un ensayo después de cualquiera de las dos operaciones. Los ensayos incluyeron a 4717 hombres, a 2736 de los cuales se les había realizado una intervención conservadora activa. Había considerable variación en las intervenciones, las poblaciones y las medidas de resultado. No hubo datos disponibles para muchos de los resultados preestablecidos. Los síntomas de los pacientes mejoraron con el transcurso del tiempo independientemente del tratamiento.

No hubo evidencia de ocho ensayos de que el entrenamiento de los músculos del suelo pélvico con o sin biorretroalimentación fuera mejor que el control para los hombres que tenían incontinencia urinaria hasta 12 meses después de la prostatectomía radical; la calidad de la evidencia se consideró moderada (por ejemplo, el 57% con incontinencia urinaria en el grupo de intervención versus el 62% en el grupo de control, riesgos relativos (RR) para la incontinencia después de 12 meses 0,85, intervalo de confianza (IC) del 95%: 0,60 a 1,22). Un gran ensayo multicéntrico de tratamiento individual no mostró diferencias en ninguna medida de resultado urinario o de calidad de vida y tuvo IC estrechos. Parece poco probable que los hombres se beneficien de la terapia de EMSP individual después de la RTUP. Ensayos individuales pequeños proporcionaron datos que indican que la estimulación eléctrica, la inervación magnética externa o combinaciones de los tratamientos podrían ser beneficiosas, pero la evidencia fue limitada.

Entre los ensayos de tratamiento conservador para todos los hombres después de la prostatectomía radical, dirigidos tanto al tratamiento como a la prevención, hubo evidencia moderada de un beneficio general del entrenamiento de los músculos del suelo pélvico frente al tratamiento de control en cuanto a la reducción de la incontinencia urinaria (por ejemplo, 10% con incontinencia urinaria después de un año en los grupos de intervención frente al 32% en los grupos de control, RR para la incontinencia urinaria 0,32, IC del 95%: 0,20 a 0,51). Sin embargo, este hallazgo no fue apoyado por otros datos provenientes de pruebas con protectores absorbentes. Los resultados deben tratarse con cautela porque el riesgo de evaluación del sesgo mostró limitaciones metodológicas.

Los hombres de un ensayo mostraron mayor satisfacción con un tipo de dispositivo de compresión externo que mostró la menor pérdida de orina, en comparación con otros dos dispositivos o con ningún tratamiento. El efecto de otras intervenciones conservadoras, como los cambios en el estilo de vida, siguió sin determinarse, ya que no se identificaron ensayos que incluyeran esas intervenciones.

Conclusiones de los autores

No se ha podido precisar el valor de los diversos enfoques para el tratamiento conservador de la incontinencia posterior a la prostatectomía radical. La evidencia es contradictoria y, por lo tanto, todavía se necesitan ensayos controlados aleatorizados (ECA) rigurosos y con un poder estadístico de decisión adecuado, que se atengan a los principios y recomendaciones de la declaración CONSORT, para obtener una respuesta definitiva. Los ensayos deben estar sólidamente diseñados para responder a preguntas específicas de investigación bien construidas e incluir resultados que sean importantes desde la perspectiva del paciente en la toma de decisiones y que también sean relevantes para los profesionales de la salud. La incontinencia a largo plazo puede ser tratada con pinza peneana externa, pero hay problemas de seguridad.

Resumen en términos sencillos

Tratamiento conservador para hombres con incontinencia urinaria posterior a la cirugía de próstata

Antecedentes

La próstata es una glándula sexual masculina que rodea la salida de la vejiga. Dos enfermedades principales de la próstata (el cáncer y el agrandamiento prostático benigno [no canceroso]) se pueden tratar mediante cirugía, aunque posteriormente algunos hombres presentan pérdida de orina (incontinencia urinaria). Se considera que el tratamiento conservador de la pérdida, como el entrenamiento muscular del suelo pélvico con o sin biorretroalimentación o la estimulación eléctrica anal, ayudan a los hombres a controlar esta pérdida.

Principales hallazgos de la revisión

La revisión de los ensayos encontró evidencia contradictoria acerca del beneficio de que los terapeutas enseñen a los hombres a contraer los músculos del suelo pélvico para la prevención o el tratamiento de la pérdida de orina posterior a la cirugía radical de próstata por cáncer. Sin embargo, la información de un ensayo grande indicó que los hombres no se benefician al recibir entrenamiento muscular del suelo pélvico por un terapeuta después de la RTUP por agrandamiento benigno de la próstata. En general, no hubo evidencia suficiente para demostrar un efecto beneficioso del entrenamiento de los músculos del suelo pélvico.

De los tres dispositivos de compresión externa probados, una pinza para el pene parecía ser mejor que los otros.

Efectos adversos

Esta única pinza para el pene debía usarse con precaución debido a los riesgos de seguridad.

Posibles limitaciones de la revisión

En futuras actualizaciones, puede valer la pena considerar dos revisiones separadas, mirando por separado los ensayos de "tratamiento" y "prevención". También se necesitan más investigaciones de mejor calidad para evaluar el tratamiento conservador.

Authors' conclusions

Implications for practice

In keeping with conclusions from earlier versions of this review, at this point there remains no clear support that conservative management of any type is helpful for postprostatectomy UI whether delivered as treatment to men who are incontinent or as prevention to all men undergoing radical prostatectomy. The individual result of one large multi‐centre trial on its own did have narrow confidence intervals which did not include a clinically significant difference (of 15%) in the rate of incontinence between the groups. It seems unlikely that men benefit from one‐to‐one PFMT therapy after TURP.  

Some small trials provided data to suggest that electrical stimulation was better than control interventions (in one trial including sham electrical stimulation), or active interventions which did not include electrical stimulation, at least in the short term up to six months. Individual small trials provided data to suggest that extra‐corporeal magnetic innervation (ExMI) or combinations of treatments might be beneficial but the evidence was limited.

The trials suffered from a lack of standardised outcome measures. Definitions of incontinence, measurement of quality of life and types of pad tests (20 minute, 1 hour, 24 hour, number of pads, weight of pads, number of men using pads and so on) varied in almost every trial. The timing for measuring the primary outcome should be at least 1 year.

No trials have tested the effect of lifestyle changes alone. Long‐term UI may be managed by absorbent pads or external penile clamps, but there are safety problems with clamps.

This review did not find sufficient evidence as to whether or not conservative management is effective in treating or preventing postprostatectomy UI.

Implications for research

Urinary incontinence (UI) after prostatectomy is a distressing problem and, although conclusive evidence does not exist, conservative approaches form part of current management. Well‐designed clinical trials are still needed to clarify the role of these therapies. In addition, men with persistent severe UI could consider surgical treatment for example with an artificial urinary sphincter or male sling. However, these surgical options should also be tested in RCTs as there is currently not enough evidence to support their use (Silva 2011).

As there are known differences in the cause and prevalence of UI between men after TURP and after radical prostatectomy, these groups of men should continue to be studied separately. Prevention trials in all men having surgery should be evaluated separately from treatment trials of men who all have urinary incontinence after surgery.

Most of the trials included in this review used very different protocols, of intervention type, timing and intensity. In order to determine the effects of specific protocols and modalities, large adequately powered trials using common protocols and common standardised outcome measures are needed. Replication studies using similar protocols in different populations would also assist in identifying the populations in which specific conservative management approaches may be effective.

Definitions and measurement of outcomes varied in the included trials. Future trials must attempt to use broadly accepted validated outcome measures, such as those of the International Continence Society (ICS). The primary outcome measure should be the participant's self‐reported UI or its effects on his quality of life. Other objective measures such as the pad test or urinary diaries can be used to determine if continence has been achieved. Researchers must also focus on either the 1 hour or 24 hour pad test, as the results of these two measurements are not equivalent.

Lastly, authors should be encouraged to ensure appropriate measures are taken to avoid the risk of bias from selection, performance, detection and attrition bias, in particular adequate sequence generation and secure concealment of allocation for randomisation, and blinding of outcome measurement, and to report these adequately using the guidelines of the CONSORT statement.

Background

Description of the condition

It is not uncommon for men to have urinary incontinence (UI) after prostatectomy. UI can be divided into three groups of urgency urinary incontinence (UUI), stress urinary incontinence (SUI) and mixed urinary incontinence (MUI). UUI is described by the International Continence Society (ICS) as the complaint of involuntary leakage of urine associated with a sudden desire to void urine (Altman 2013). SUI is defined as the involuntary leakage of urine with concurrent coughing, sneezing or physical exertion, whilst MUI, as the name suggests, is a mixture of the symptoms found in both of these types (Altman 2013). The reported frequency varies depending on the type of surgery and surgical technique (Grise 2001; Peyromaure 2002), the definition and quantification of incontinence (Grise 2001; Peyromaure 2002), the timing of the evaluation relative to the surgery, and who evaluates the presence or absence of incontinence (physician or patient) (Donnellan 1997; McCammon 1999). Furthermore, the costs associated with UI can be substantial. The annual cost to the National Health Service (NHS) in the UK for treating clinically significant storage symptoms in men was estimated to be GBP 303 million (Turner 2004) and the annual direct cost of UI in the US was estimated to be USD 3.8 billion (Wilson 2001).

The prevalence of UI after radical prostatectomy is widely reported, ranging from 2% to 60%, albeit at varying times after operation (Milsom 2009). For example, in one study at three months after radical prostatectomy (Donnellan 1997) 51% were subjectively wet (self‐report) but 36% were wet on pad testing (objective reporting). By 12 months, 20% were subjectively still wet but only 16% were classed as wet using objective criteria.

UI is less common after transurethral resection of the prostate (TURP) for benign prostate disease (Omar 2014) and most cases are due to persistent incontinence pre‐dating the surgery. Early UUI affects up to 30% to 40% of men but late SUI is rare affecting less than 0.5% of men (Rassweiler 2006). This is a less invasive operation than a radical prostatectomy and usually does not involve damage to pelvic nerves. Due to these clinical differences, we have analysed data relating to TURP separately.

After both types of operation the problem tends to improve with time, so that it declines and plateaus within one to two years postoperatively (Hunskaar 2002). However, some men are left with incontinence that persists for years afterwards.

Continence mechanisms

Urinary continence depends on a complex interaction of smooth and striated muscle fibres blended together to form the continence mechanism. Considerable debate has existed in the literature as to whether incontinence after prostatectomy is due to an effect on the detrusor (bladder) muscle or on the sphincter, as commonly these abnormalities coexist (Peyromaure 2002). New detrusor overactivity and intrinsic sphincter deficiency due to sphincteric injury (Ficazzola 1998; Groutz 2000; McGuire 1990) or weakness (Majoros 2006) are cited as the most important causes of persistent incontinence after radical prostatectomy. Debate continues on whether detrusor overactivity is a primary or secondary factor. Whereas some report overactivity as the primary cause of postprostatectomy incontinence (Golubuff 1995; Leach 1995) others argue strongly that even if other factors play a role, intrinsic sphincter deficiency is the primary cause of UI after radical prostatectomy (Aboseif 1996; Chao 1995; Groutz 2000; Gudziak 1996; Kondo 2002; Majoros 2006; Winters 1997).

Risk factors for postprostatectomy UI after radical prostatectomy include pre‐existing abnormalities of detrusor contractility (Leach 1995) and older age (Kondo 2002). This is possibly because in older men there is evidence of rhabdosphincter atrophy and neural degeneration (Burnett 1998; Chao 1995). Other risk factors include previous TURP (Jacobsen 2007); pre‐operative radiotherapy (Kondo 2002; Rainwater 1988); trauma; a spinal cord lesion; new obstruction due to recurrence, bladder neck contracture, or urethral stricture (Litwiller 1997); Parkinson's disease (Kondo 2002); dementia; and medications (Khan 1991). A surgeon's inadequate skill and expertise can determine post‐operative incontinence rates (Eastham 1996). In addition, having surgery in a hospital which performs fewer than 20 radical prostatectomies a year may be a factor (Albertsen 1997).

After TURP, UI is thought most likely to be due to pre‐existing abnormalities of bladder function, such as poor compliance or detrusor overactivity, rather than direct sphincter injury (Abrams 1991), possibly because removal of the prostatic tissue removed some of the protective mechanism for continence.

Description of the intervention

Many of the treatments used in current practice for postprostatectomy UI are 'conservative', which is usually considered as not involving drugs or surgery. Treatments such as biofeedback with surface intra‐anal probes are defined as non‐invasive in this context, as opposed to surgical interventions. Five categories of conservative management are considered in this review, both singly and in combination when appropriate.

1. Pelvic floor muscle training (PFMT)

This involves any method of training the pelvic floor muscles to contract. It includes teaching performance of an accurate voluntary pelvic floor muscle contraction using biofeedback and co‐ordinating and timing the contraction against increases in intra‐abdominal pressure, often called functional PFMT.

Traditionally, biofeedback involves the use of equipment to provide visual or auditory feedback about the pelvic floor muscle function to enable one to train, strengthen and increase endurance and co‐ordination of the pelvic floor muscle contractions. Simple auditory biofeedback can also be provided by the therapist informing the patient when a contraction is felt through digital anal examination during the pelvic floor muscle contraction. Additionally, pelvic floor muscle contraction electromyography (EMG) can be used as a surrogate for biofeedback, as well as for measuring the intra‐rectal pressure.

The theoretical basis of PFMT is that repeated, volitional contractions of selected pelvic floor muscles may improve their strength and efficiency during periods of increased intra‐abdominal pressure and can inhibit detrusor activity. In a systematic review of the literature on female UI, Berghmans and colleagues noted that a pelvic floor muscle contraction may raise the urethra and press it towards the symphysis pubis, prevent urethral descent, and improve structural support of the pelvic organs (Berghmans 1998). They further pointed out that PFMT may result in hypertrophy of the peri‐urethral striated muscles thereby increasing the 'external mechanical pressure' on the urethra.

2. Electrical stimulation (non‐invasive) delivered via surface electrodes

Electrical stimulation (ES) works by activating the motor fibres of the pudendal nerve, which can result in contraction of the pelvic floor muscles or the striated peri‐urethral musculature, supporting the intrinsic part of the urethral sphincter closing mechanism (Berghmans 2013). This may be important in the management of men with SUI by stimulating the intrinsic sphincter, strengthening the pelvic muscles and raising the patient's awareness of these muscles in a similar way to biofeedback. ES can also be helpful in men with detrusor overactivity or UUI because it can stimulate afferent fibres of the pudendal nerve, decreasing the sensation of urgency and inhibiting parasympathetic activity which results in a decrease in involuntary detrusor contractions (Berghmans 2013). Two types of non‐invasive ES are detailed below. The parameters of the ES used in studies vary depending on the type of UI and ES. Parameters include pulse width and duration, current intensity, stimulus frequency, current source, pulse shape, duration of treatment and total number of sessions, and rest to work ratio.

Anal electrical stimulation (ES)

Any type of ES using a non‐invasive surface anal probe designed for the therapy. The intention of ES is to facilitate contraction of the peri‐urethral striated muscle by inserting the probe into the anal canal (Jabs 2001).

Sticky patch electrodes, also called transcutaneous electrical nerve stimulation (TENS)

TENS is a low intensity, sensory nerve stimulation used for detrusor overactivity. It is delivered at various sites using patch electrodes. Sites include the sacral dermatomes, dorsal penile nerve, hamstring and quadriceps muscle, and the posterior tibial or perineal nerves (Berghmans 2013).

3. Lifestyle adjustment

This includes fluid adjustment, healthy diet, avoiding excessive caffeine, physical exercise, weight loss and cessation of smoking.

4. Extra‐corporeal magnetic innervation

This involves the use of a magnetic chair to stimulate contraction of the pelvic floor muscles and sacral nerve roots, without the discomfort of inserting an anal probe (Galloway 2000).

5. External penile compression devices (penile clamps)

These devices use an external clamp to achieve non‐surgical compression of the urethra.

Timing of the intervention

Conservative treatment can be started before or after surgery. In general, when it is delivered to all men (whether before or after) the aim is to prevent the development or persistence of UI. We have therefore distinguished between treatment of all men who do have UI (treatment) as opposed to a mixed population of men some of whom do not have UI (prevention).

How the intervention might work

All of these interventions, apart from lifestyle adjustment and a penile clamp, work by inducing contraction of pelvic muscles to increase their strength and efficiency, whilst improving co‐ordination and bladder control by inhibiting overactive detrusor activity. Repetitive contractions can raise urethral closure pressure at rest and during an increase in intra‐abdominal pressure.

Why it is important to do this review

The uncertainty about the benefit of conservative treatment for men with UI after prostate surgery was confirmed in the initial Cochrane review, first published in 1999 (Moore 1999b) and updated in 2001 (Moore 2001). The review originally only considered post‐operative PFMT, biofeedback and electrical stimulation. In a subsequent update (Hunter 2004) the review was broadened to include trials evaluating lifestyle adjustment, external penile compression devices and extracorporeal magnetic innervation. The most recent update also included trials on men after TURP (Hunter 2007) but still did not provide reliable evidence on the effects of conservative treatment. The current update includes 13 new trials.

Objectives

To determine the effectiveness of conservative management for urinary incontinence (UI) up to 12 months after transurethral or radical retropubic prostatectomy, including any single conservative therapy or any combination of conservative therapies.

Methods

Criteria for considering studies for this review

Types of studies

Randomised controlled trials and quasi‐randomised trials of conservative management to prevent or treat UI after TURP or radical prostatectomy were included. Trials were included if they used any single conservative therapy or any combination of conservative therapies. Other forms of clinical trials were excluded. Analysis of trials in men having radical prostatectomy was done separately from those in men having a TURP.

Types of participants

Adult men with UI following prostatectomy.

Types of interventions

PFMT; biofeedback (verbal or machine‐mediated); electrical stimulation (ES) via a surface electrode (e.g. anal probe ES, sticky patch electrode, transcutaneous electrical nerve stimulation (TENS)); extra‐corporeal magnetic innervation (ExMI); lifestyle adjustment; and external penile compression devices. These interventions could be compared with no treatment or with each other, alone or in combination.

The following comparisons were made for treatment or prevention of UI after prostatectomy.

Containment of urinary incontinence (UI) from any cause

(21) External penile compression devices (penile clamps) versus no treatment or sham treatment

We have not listed all possible comparisons here. As and when new trials address new comparisons these will be added to the review.

Pharmacological agents will be considered in separate reviews. Verbal or written instructions, as well as sham therapy, were considered as 'no treatment'. The use of the term 'sham therapy' in this review meant any therapy that could not influence the pelvic floor muscles such as placing an ES probe in the anus but not turning it on.

The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach (Guyatt 2011a; Guyatt 2011b; Guyatt 2013; Guyatt 2013a). This approach divides the quality of evidence into four categories: high, moderate, low and very low. Randomised controlled trials (RCTs) start as high quality evidence and non‐randomised trials begin as low quality evidence. The quality of evidence can be rated down for RCTs and up or down for non‐RCTs depending on predefined characteristics. The factors considered when assessing the quality of evidence included:

  1. limitations in study design and implementation;

  2. indirectness of evidence;

  3. unexplained heterogeneity or inconsistency of results;

  4. imprecision of results;

  5. high probability of publication bias.

Primary and secondary outcomes were classified as critical, important or not important for decision making from the man’s perspective. The GRADE working group strongly advises a maximum of seven outcomes in a systematic review (Guyatt 2011a). The critical outcomes for assessing quality of evidence included in this review were:

  1. number of men reporting UI after 12 months;

  2. quality of life assessed using the ICIQ‐UI‐SF;

  3. number of men reporting adverse effects;

  4. cost effective analysis.

Search methods for identification of studies

We did not impose any language or other limits on the searches. Details of the search methods used for the previous versions of this review can be found in Appendix 1 and Appendix 2.

Electronic searches

This review has drawn on the search strategy developed for the Incontinence Review Group. Relevant trials were identified from the Incontinence Review Group Specialised Register of controlled trials which is described, along with the Group's search strategy, in the Incontinence Group's module in The Cochrane Library. The register contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In‐Process, and handsearching of journals and conference proceedings. The Incontinence Group Specialised Register was searched using the Group's own keyword system; the search terms used were:
({design.cct*} OR {design.rct*})
AND
({topic.urine.incon.postprost*})
(All searches were of the keyword field of Reference Manager 2012).
The date of the most recent search of the Specialised Register for this review was 5 February 2014. Most of the trials in the Incontinence Group Specialised Register are also contained in CENTRAL.

Specific searches were also performed for this update of the review.

  • CENTRAL (OvidSP) (2014, Issue 1) was searched on 26 February 2014.

  • EMBASE (OvidSP) (January 2010 to Week 3 2014) was searched on 20 January 2014.

  • CINAHL (EBSCOhost) (January 1982 to 18 January 2014) was searched on 22 January 2014.

  • ClinicalTrials.gov (via the Cochrane Register of Studies (CRS) interface) and World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (both searched on 29 January 2014).

The strategies used to search these databases can be found in Appendix 3.

Searching other resources

Reference lists of relevant articles

The reference lists of relevant articles were searched for other possibly relevant trials.

Contact with investigators in the field

We contacted investigators to ask for other possibly relevant trials, published or unpublished.

Data collection and analysis

Comparisons of the outcomes of the chosen interventions with no treatment, with each other, and in combination were planned a priori for the review update. Data were not available for all planned comparisons. There was considerable diversity in the length of time interventions were carried out for and in the timing of outcome measurements relative to randomisation. The data were therefore reported at three monthly time points.

Selection of studies

The list of abstracts for each update was reviewed independently by two review authors and results compared. The full text articles of references or abstracts identified as potentially relevant by either review author were retrieved and reviewed by both. Reference lists of relevant review articles were reviewed to identify any further trials. References were assessed based on the population, interventions, control management, outcomes and overall study design. Using the full texts of the potentially relevant published studies and abstracts, the same two review authors independently reviewed the studies for relevance and inclusion. Authors were contacted for further data or clarification of methods. Disagreements were resolved through discussion; third party arbitration was not required.

Attempts were made to contact authors of trial reports if clarification was necessary. Studies were excluded from the review if they made comparisons other than those pre‐specified or if data were unavailable. Excluded studies were listed with reasons for their exclusion.

Data extraction and management

Data for the trials were extracted independently by two review authors using a standard form developed for this purpose. The following information was included:

  • study method and characteristics (design, method of randomisation, inclusion and exclusion criteria, withdrawals and dropouts);

  • participants (type of surgery, age, timing of randomisation, baseline incontinence or not);

  • type of intervention, timing (before or after surgery, or both) and duration of therapy, co‐interventions;

  • control (no treatment or sham therapy or other active treatment);

  • outcomes (types of outcome measures, reported outcomes, adverse events).

Extracted data were compared by two review authors for completeness and accuracy, and cross‐checked by another review author if necessary. Disagreements were resolved through discussion and review of the trial report. New data were entered using RevMan5 software.

Assessment of risk of bias in included studies

The risk of bias of the trials was assessed using the Cochrane 'risk of bias' tool.

The following methodological parameters were recorded:
1) identification of study as randomised or quasi‐randomised;
2) description of inclusion and exclusion criteria;
3) potential for selection bias (method of sequence generation, adequacy of random allocation concealment) rating;
4) potential for bias around the time of treatment or during outcome assessment (blinding of participants, personnel, outcome assessors);
5) potential for selection bias in the analysis (description of withdrawals, dropouts, participants lost to follow up, analysis based on intention to treat).

Measures of treatment effect

Analyses were based on available data from all included trials that were relevant to the comparisons and outcomes of interest. Meta‐analysis was undertaken where data were available from more than one study assessing the same outcome. A fixed‐effect model was used for calculations of pooled estimates and their 95% confidence intervals (CIs), or a random‐effects model if there was heterogeneity. For categorical outcomes we related the numbers reporting an outcome to the numbers at risk in each group to calculate a risk ratio (RR) with 95% CI. For continuous variables we used means and standard deviations to calculate a mean difference (MD) with 95% CI. If similar outcomes were reported on different scales, we calculated the standardised mean difference (SMD). We reversed the direction of effect if needed to ensure consistency across trials. If data to calculate RRs or MDs were not given, we utilised the most detailed numerical data available to calculate the actual numbers or means and standard deviations (for example test statistics, P values).

Unit of analysis issues

The primary analysis was per man randomised.

Dealing with missing data

Analysis of the data was on an intention‐to‐treat basis to the furthest possible extent. This meant all participants were analysed in the groups to which they were randomised. If this was not the case, we considered whether to exclude the trial. Attempts were made to obtain missing data from the original trialists. However, if this was not possible data were reported as given in the studies, except if there was evidence of differential loss to follow up from the randomised groups. In that case, the use of imputation of missing data was considered. If trials reported sufficient detail to calculate MDs but gave no information on the associated standard deviation (SD), the outcome was assumed to have a SD equal to the highest SD from other trials within the same analysis.

Assessment of heterogeneity

Trials were only combined if they were thought to be clinically similar. We assessed heterogeneity between studies by visual inspection of plots of the data, the Chi2 test for heterogeneity and I2statistic (Higgins 2011). We used the thresholds for interpretation of the I2 statistic in accordance with the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2003).

Assessment of reporting biases

Due to the difficulty of detecting and correcting for publication bias and other reporting biases, the authors aimed to minimise their potential impact by ensuring a comprehensive search for eligible studies and by being careful to watch for duplication of data. Funnel plots could not be utilised because there were fewer than 10 trials in each meta‐analysis.

Data synthesis

Included trial data were processed as described in the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2011).

For dichotomous outcomes, data were summarised (for example number of people for whom an outcome is present or not) and risk ratios (RR) calculated with their 95% CIs. For continuous outcomes, each trial was summarised using the mean value for each group and SD, and combined as mean difference (MD) if the same scale (for example pad test in grams of urine) was used for the outcome measurement in more than one trial. A fixed‐effect model was used to calculate the summary statistic and the 95% CI. Heterogeneity was assessed visually and using the Chi2 test for heterogeneity and the I2 statistic (Higgins 2003). Forest plots were examined and potential sources influencing heterogeneity identified. Possible sources of heterogeneity were explored statistically through subgroup analysis. Where synthesis was deemed not appropriate, a narrative overview was planned.

Trials were combined if interventions were based on similar clinical criteria. To combine trial data, a meta‐analysis was conducted and a fixed‐effect model approach to the analysis was utilised unless there was evidence of heterogeneity across studies, in which case a random‐effects model was used.

Subgroup analysis and investigation of heterogeneity

We planned to perform subgroup analysis based on cancer stage but there were not enough data.

Sensitivity analysis

We planned to perform sensitivity analysis to investigate the effect of including or excluding trials at high risk of bias, however not enough trials were in the meta‐analysis.

Description of studies

Results of the search

For the current update (2014) of the review 764 possibly relevant articles and abstracts were identified. Sources and numbers of potentially eligible titles were:

  • Incontinence Review Group Specialised Register (193);

  • CENTRAL (37);

  • updated search of EMBASE (354);

  • CINAHL (23);

  • ClinicalTrials.gov (125);

  • WHO ICTRP (32).

Overall 96 reports of 50 studies were included in the qualitative synthesis. Fifty‐nine reports of 27 studies were included in the quantitative synthesis. Four trials are awaiting further information from the authors (Crivellaro 2011;Delmastro 2010; Lilli 2006 NEW; Zhang 2007) and eight trials are ongoing (Burnett 2012; Burnett 2013;Fode 2012 NEW;Goode 2014;Mina 2013; Ng 2011;Terrone 2007; Zopf 2012).

Forty‐one reports of 36 studies were excluded and reasons are given in the 'Characteristics of excluded studies' table. The flow of the literature through the assessment process is shown in the PRISMA study flow chart (Figure 1).

New included trials

After abstract and full text screening 13 relevant new trials (Ahmed 2012;Dijkstra‐Eshuis 2013; Fader 2013; Fode 2014; Geraerts 2013;Ghanem 2013; Hou 2013; Laurienzo 2013; Marchiori 2010; Martini 2011; Morihiro 2011; Park 2012; Tienforti 2012) were identified. We also identified 12 new reports of the trials which were already identified in the previous update (Campbell 2012). The trialists were contacted for additional information and data.

One previously included trial published as an abstract was updated with data from a full publication (Centemero 2009).

Included studies

Types of populations

The trials included 4717 men, of whom 2736 had an active conservative intervention.

Surgery

Forty‐five trials involved patients undergoing radical prostatectomy (Ahmed 2012;Bales 2000;Burgio 2006;Centemero 2009;Dijkstra‐Eshuis 2013;Dubbelman 2004;Fader 2013;Filocamo 2005;Floratos 2002;Fode 2014;Franke 1998;Geraerts 2013;Ghanem 2013;Glazener RP 2011;Goode 2009;Hoffman 2005;Koo 2009;Laurienzo 2013;Liu 2008;Manassero 2007;Marchiori 2010;Mariotti 2009;Martini 2011;Mathewson‐Chapman 97;Moore 1999;Moore 2004;Moore 2008;Morihiro 2011;Nowak 2007;Opsomer 1994;Overgard 2008;Park 2012;Parekh 2003;Perissinotto 2008;Ribeiro 2008;Robinson 2008;Robinson 2009;Seleme 2008;Tienforti 2012;Tobia 2008;van Kampen 1998;Wille 2003;Yamanishi 2006;Yokoyama 2004;Zhang 2007).

One very small trial included one patient having a TURP while the rest were radical prostatectomy patients (Joseph 2000) but this was included in the radical prostatectomy group for analysis. Also, as all the men in this trial were incontinent for some time after surgery, they may have represented a group with persistent (longer than one to two years) UI. There were many potentially confounding variables in this trial, acknowledged by the author.

Four trials involved patients after TURP (Glazener TURP 2011;Hou 2013;Porru 2001;Tibaek 2007).

The trials involving post‐TURP patients only (Glazener TURP 2011; Hou 2013; Porru 2001; Tibaek 2007) were analysed separately from the trials amongst men having radical prostatectomy.

Continence status of populations

There was variation in continence status, which led to different populations being studied separately: those with persistent UI and those with all men undergoing surgery (many of whom were likely to recover continence spontaneously). The comparisons were therefore structured to reflect this: trials which included only men with post‐operative incontinence were deemed to be trials of treatment, while trials in which all men were treated (irrespective of continence status) were deemed to be trials of prevention.

Timing of recruitment

As the populations and the type and timing of interventions varied so greatly among the trials, the decision was made by the authors to also identify the timing of the recruitment to the trials and the timing of the intervention (before or after surgery):

Time of recruitment of participants to the trial relative to the time of their surgery also varied:

Types of interventions

In the included trials, there was considerable variation in the type and intensity of interventions. Table 1 gives the exact details of the interventions used in each trial. The duration of the treatment varied from four weeks up to one year. The interventions included:

Types of comparators

There was considerable variation in the types of comparators. Table 1 provides the details of the comparators used in each trial. The comparators included:

Types of outcome measures

There was a lack of consistency in the reporting of outcome measures. In terms of the primary outcomes of interest in this review these included:

Excluded studies

In total 36 studies were excluded. The majority of the studies that did not meet the inclusion criteria were excluded because the study design was not appropriate or the intervention was not relevant for the population of interest. See the Excluded studies table for a more detailed description.

Risk of bias in included studies

The assessment criteria of The Cochrane Collaboration assume that the avoidance of bias is best achieved by: a randomised trial with an adequate method of random sequence generation; secure concealment of allocation prior to formal entry; adequate blinding of patients, healthcare providers and outcome assessors; description of reasons and numbers of withdrawals and dropouts; and analysis on an intention‐to‐treat basis. None of the early trials fulfilled all these criteria. However recent trials have fared much better in terms of secure concealment of allocation and blinding but overall this continues to be problematic in many trials (Figure 2; Figure 3).

Allocation

Sequence generation

Although all trials were identified as RCTs only 24 trials (Ahmed 2012; Burgio 2006; Centemero 2009; Dijkstra‐Eshuis 2013; Dubbelman 2004; Filocamo 2005; Fode 2014; Glazener RP 2011; Glazener TURP 2011; Goode 2009; Laurienzo 2013; Manassero 2007; Mathewson‐Chapman 97; Moore 1999; Moore 2004; Moore 2008; Overgard 2008; Park 2012; Robinson 2008; Robinson 2009; Tibaek 2007; Tienforti 2012; van Kampen 1998; Yamanishi 2006) described a method of adequate sequence generation (for example computer generated random numbers) and were assessed as low risk of bias. The remainder did not provide enough information to make a judgement and were assessed as unclear.

Allocation concealment

Only 20 trials (Ahmed 2012; Burgio 2006; Centemero 2009; Dijkstra‐Eshuis 2013; Dubbelman 2004; Fode 2014; Geraerts 2013; Glazener RP 2011; Glazener TURP 2011; Goode 2009; Manassero 2007; Moore 1999; Moore 2004; Moore 2008; Overgard 2008; Park 2012; Robinson 2008; Tibaek 2007; van Kampen 1998; Yamanishi 2006) adequately described a technique of allocation concealment (for example sealed envelopes or computerised randomisation) and were assessed as low risk of bias. The remainder did not provide enough information to make a judgement and were assessed as unclear.

Blinding

Blinding was not described in most trials. In complex interventions such as physical therapy it is not possible to blind either the clinicians or the participants from the intervention, however, if blinding did not take place in trials they were judged to be at high risk of bias. This may have an impact on the outcome of interest and was considered while assessing the quality of evidence. Yamanishi 2006 used a sham device for the control group and this was the only trial that was deemed to be at low risk of bias in terms of blinding of participants.

In terms of blinding of personnel:

Burgio 2006; Moore 1999 and Moore 2008 indicated that a single therapist, blinded to control group outcomes, provided all treatment. Dijkstra‐Eshuis 2013 and Geraerts 2013 reported that the post‐operative physiotherapist was blinded to allocation and physical therapy provided by the pre‐operative therapist.

In terms of blinding of outcome assessment:

Yamanishi 2006 used a sham device for the control group but there was no statement of whether assessors were aware of this or not.

Incomplete outcome data

Several trials gave no description or did not report dropouts (Centemero 2009; Ghanem 2013; Koo 2009; Marchiori 2010; Morihiro 2011; Perissinotto 2008; Ribeiro 2008; Robinson 2009; Seleme 2008; Yamanishi 2006; Yokoyama 2004), or did not have withdrawals or dropouts (Bales 2000; Liu 2008; Moore 2004; Tobia 2008).

All others reported the number of withdrawals or dropouts, although the reasons were not consistently reported and few, except Moore 2008 and Robinson 2008, discussed how this was dealt with in the analysis. In one trial, outcomes beyond eight weeks were not available for the control group because all the men were treated, and data were not available for over a third of the men in the other two intervention groups (Goode 2009). Two trials were thought to be at risk of bias because of differential dropout from the randomised groups (Dubbelman 2004; Manassero 2007). One trial (Marchiori 2010) that was judged to be at high risk of bias reported that the survey questionnaire used for one of their outcomes was completed correctly but returned by fewer than 10% of the men.

Six trials (Fader 2013; Martini 2011; Nowak 2007; Perissinotto 2008; Robinson 2008; Robinson 2009) did not provide any usable data. Three of these trials (Nowak 2007; Perissinotto 2008; Robinson 2009) did not report how many men were randomised to each group.

Selective reporting

There was significant difficulty in assessing selective outcome reporting because the protocols for most of the included trials were not available for assessment or could not be found. For a few of the trials, data were not available for some of the outcomes stated in the methods section.

Other potential sources of bias

Information about funding was available for 27 of the included studies (Burgio 2006; Centemero 2009; Dijkstra‐Eshuis 2013; Fader 2013; Fode 2014; Franke 1998; Geraerts 2013; Ghanem 2013; Glazener RP 2011; Glazener TURP 2011; Goode 2009; Laurienzo 2013; Moore 1999; Moore 2004; Moore 2008; Morihiro 2011; Overgard 2008; Park 2012; Perissinotto 2008; Ribeiro 2008; Robinson 2008; Robinson 2009; Seleme 2008; Tibaek 2007; van Kampen 1998; Yamanishi 2006; Zhang 2007) and the studies were judged to be at low risk of bias. The rest of the trials were judged to be at unclear risk of bias because there was a lack of information even after contacting the authors.

Thirty‐two trials reported obtaining approval from a medical ethics committee (Ahmed 2012; Burgio 2006; Centemero 2009; Dijkstra‐Eshuis 2013; Dubbelman 2004; Fader 2013; Filocamo 2005; Fode 2014; Geraerts 2013; Ghanem 2013; Glazener RP 2011; Glazener TURP 2011; Goode 2009; Laurienzo 2013; Liu 2008; Manassero 2007; Mathewson‐Chapman 97; Moore 1999; Moore 2004; Moore 2008; Morihiro 2011; Overgard 2008; Park 2012; Perissinotto 2008; Ribeiro 2008; Robinson 2008; Robinson 2009; Seleme 2008; Tibaek 2007; Tienforti 2012; Yamanishi 2006; Yokoyama 2004) and were judged to be at low risk of bias. The remaining 18 trials did not report their source of medical ethical approval and were judged to be at unclear risk of bias after no further information was provided by the authors.

Fourteen trials were deemed to be at unclear risk of bias in terms of obtaining informed consent (Bales 2000; Burgio 2006; Hoffman 2005; Hou 2013; Joseph 2000; Koo 2009; Liu 2008; Marchiori 2010; Martini 2011; Nowak 2007; Opsomer 1994; Parekh 2003; Tobia 2008; Zhang 2007). These authors were contacted but no further information on this matter was provided. The other trials did report obtaining informed consent from patients and therefore were deemed to be at low risk of bias for this domain.

Radical prostatectomy: treatment of incontinent men after surgery

1. Treatment of UI after radical prostatectomy: post‐operative PFMT with or without biofeedback versus no treatment or sham therapy or verbal instruction (Comparison 1)

Nine trials (Dubbelman 2004; Floratos 2002; Franke 1998; Manassero 2007; Glazener RP 2011; Goode 2009; Moore 1999; Moore 2008; van Kampen 1998) compared PFMT with or without biofeedback to no treatment (sham or verbal instruction) amongst men who had UI after radical prostatectomy. The quality of the evidence is given in summary of findings Table for the main comparison.

Differences between trials

All the men were incontinent at baseline.

In one trial (Manassero 2007) there was evidence of unexplained differential dropout from the control group (13 of 53 men, while there were no dropouts from the 54 in the intervention group). The missing men have therefore been assumed to be dry for the purpose of an intention‐to‐treat analysis. The other trials have been analysed as reported since dropouts (if any) were balanced between the groups.

Sources of heterogeneity

(1) Definition of incontinence varied with each trial:

(2) The type of PFMT regimens differed between the trials:

Formal PFMT post‐operative sessions directed by a therapist ranged from: twice a week for 12 weeks (Moore 1999); three times a week for three weeks (Floratos 2002); in up to nine sessions (Dubbelman 2004); weekly for 24 weeks (Moore 2008); four sessions over eight weeks (Goode 2009); five sessions over 16 weeks (Franke 1998); to as long as the UI persisted (van Kampen 1998). Men received only four therapy sessions in three months in one of these trials (Glazener RP 2011) and men in another trial were seen weekly for up to six months (Moore 2008).

(3) Control interventions differed between the trials and included:

(4) The participants differed between the trials.

Two trials (Goode 2009; Moore 1999) recruited participants with persistent incontinence (some longer than one year) post‐operatively, and these participants may have differed from those enrolled pre‐operatively (Moore 2008) but still incontinent at four weeks after surgery) or from those recruited within a week or two of catheter removal (Dubbelman 2004;Floratos 2002;Glazener RP 2011; Manassero 2007; van Kampen 1998) or up to six weeks after radical prostatectomy (Franke 1998).

Incontinence in men and incontinence episodes

Because there was evidence of significant statistical heterogeneity between the trials included in this comparison (see below), meta‐analysis was carried out using a random‐effects model, therefore widening the CI. There were no significant differences at any time period in the UI rates, and the CIs were wide (for example RR for UI up to 12 months 0.91, 95% CI 0.73 to 1.14, Analysis 1.1.3; and after 12 months 57% with UI versus 62% in the control group, RR 0.85, 95% CI 0.60 to 1.22, Analysis 1.1.4). Only two trials (Manassero 2007; van Kampen 1998) favoured the treatment and of these, only one (van Kampen 1998) used biofeedback. The estimates from the other trials had CIs that did not rule out clinically important effects. Overall, as one of the pre‐defined GRADE‐specific outcomes, the quality of evidence for the outcome 'number of incontinent men after 12 months' was found to be moderate.

The meta‐analysis was dominated by the Glazener RP 2011 trial, which was a large pragmatic multi‐centre trial conducted in a context where information on PFMT was widely available. This showed no good evidence to support one‐to‐one training by a therapist (for example RR for UI after 12 months 0.98, 95% CI 0.87 to 1.09, Analysis 1.1.4) (Glazener RP 2011). This one large trial had narrow CIs which did not include a clinically significant difference, pre‐specified to be 15%. One other trial (Moore 2008) was in line with the Glazener RP 2011 findings but had wider CIs (RR 1.02, 95% CI 0.70 to 1.48, Analysis 1.1.4) (Moore 2008).

In one large trial (Glazener RP 2011), men did not report differences in UI episodes at any time period, based on urinary diary data (for example after 12 months MD 0.1, 95% CI ‐0.82 to 1.02, Analysis 1.2.4). Alternatively, one trial (Goode 2009) did report a significant difference, however this measurement was obtained at less than 3 months (MD ‐1.14, 95% CI ‐1.46 to ‐0.82, Analysis 1.2.1).

Use of pads

Use of pads could be considered to be a measure of more severe incontinence. There was no statistically significant difference in the number of men using pads in one large trial (40% in intervention group versus 42% in control group after 12 months, RR 0.94, 95% CI 0.72 to 1.22, Analysis 1.3) (Glazener RP 2011). Floratos 2002 used number of pad changes over 24 hours as the outcome measure, with no statistically significant difference in the MD between treatment and control groups at any time period (Analysis 1.4).

Urinary incontinence score and effect on quality of life

In one large trial (Glazener RP 2011), there was no evidence of a difference in the ICIQ‐SF (a composite score of frequency, amount and effect of UI on quality of life) at any time period after the intervention up to or beyond one year (MD after 12 months ‐0.5, 95% CI ‐1.35 to 0.35, Analysis 1.5) or quality of life as a single score from 0 to 10 (MD ‐0.30, 95% CI ‐0.73 to 0.13, Analysis 1.6), however the quality of evidence for this outcome was found to be low.

Pad tests

Two trials (Moore 1999; Moore 2008) reported 24 hour pad test results and one (Floratos 2002) reported a one hour pad test. Dubbelman 2004 and van Kampen 1998 also measured urine loss on a 24 hour pad test, but did not report SDs and therefore these data could not be included in the meta‐analysis. Amongst the two trials which gave 24 hour pad test data, there were no statistically significant differences between the groups at 3, 6 or 12 months, or after 12 months (Analysis 1.8). Similarly, using a one hour pad test (Floratos 2002), there were no statistically significant differences between the groups up to six months (Analysis 1.9). In the smaller trials (Floratos 2002; Moore 1999; Moore 2008) the SDs were often larger than the means, suggesting highly skewed data.

2. Treatment of UI after radical prostatectomy: post‐operative interventions using electric or magnetic energy (for example post‐operative anal ES, perineal ES, TENS, extra‐corporeal magnetic innervation (ExMI) versus no treatment or sham treatment (Comparison 2)

Four trials were identified which addressed this comparison (Marchiori 2010; Moore 1999; Morihiro 2011; Yamanishi 2006). These trials compared anal ES with oral (verbal) PFMT. The control group in Moore's trial received oral information about PFMT only, whereas in Yamanishi's trial the control group also received sham ES. The quality of the evidence is given in summary of findings Table 2.

Number of incontinent men

In the short term (less than three months), there were fewer incontinent men in the intervention groups in two trials (64% versus 84% in the control groups, RR 0.77, 95% CI 0.60 to 0.98, Analysis 2.1.1) (Moore 1999; Yamanishi 2006) and the quality of the evidence for this outcome was deemed to be moderate. This remained the same at 6 to 12 months (19% versus 53% in the control groups, RR 0.37, 95% CI 0.18 to 0.73, Analysis 2.1.3) and after 12 months (7% versus 33% in the control groups of three trials, RR 0.26, 95% CI 0.09 to 0.74). However, the data were too few to be reliable in the longer term.

Adverse effects

One small trial (Yamanishi 2006) reported adverse effects, with two men in the active ES group and four men in the group receiving sham treatment reporting anal pain or discomfort. No statistically significant differences were found between the groups (RR 0.58, 95% CI 0.11 to 2.90, Analysis 2.2).

Pad test

There were no statistically significant differences between the groups on grams of urine lost (24 hour pad test) at any of the time points (Analysis 2.3). SSs were large, indicating skewed distribution of data, and the CIs were wide with evidence of significant statistical heterogeneity.

UI score

Men in the intervention group in one trial (Yamanishi 2006) had lower (better) UI scores using a quality of life outcome combined with amount and frequency of urine lost (for example MD ‐3.9, 95% CI ‐7.15 to ‐0.65, Analysis 2.4.3, at one year) though this did not quite reach statistical significance when quality of life was analysed on its own (MD ‐0.40, 95% CI ‐2.02 to 1.22, Analysis 2.5).

Time until continence achieved

Men achieved continence on average about 5 months sooner in the intervention group of one trial (MD ‐4.11 months, 95% CI ‐6 to ‐2.23, Analysis 2.6) (Yamanishi 2006).

3. Treatment of UI after radical prostatectomy: post‐operative lifestyle adjustment versus no treatment or sham treatment (Comparison 3)

No trials were identified.

4. Treatment of UI after radical prostatectomy: post‐operative combinations of treatments versus no treatment or sham treatment (Comparison 4)

Two trials reported using PFMT with anal ES as well as biofeedback (Goode 2009; Opsomer 1994) versus control management. Goode 2009 compared behavioural therapy comprising biofeedback and ES for eight weeks with a control group. Opsomer 1994 treated incontinent men in the intervention group with two sessions of ES with biofeedback as well as continuing the PFMT taught to both groups at six weeks after radical prostatectomy. The quality of the evidence is given in summary of findings Table 3.

Number of incontinent men

Goode 2009 reported fewer incontinent men in the intervention group compared with the control group (83% versus 94% in the control group at less than 3 months, RR 0.88, 95% CI 0.78 to 0.99, Analysis 4.1.1). In the other trial (Opsomer 1994), four men in total had incontinence at 3 to 6 months, with 3/20 in the intervention group and 1/19 in the control group, but this was not statistically significant (RR 2.85, 95% CI 0.32 to 25.07, Analysis 4.2). Overall, the quality of evidence for this outcome was very low.

Adverse events

There were two adverse events (haemorrhoidal irritation) reported by men receiving ES in one trial (Goode 2009), and the quality of evidence for this outcome was deemed to be of low quality with wide CIs indicating uncertainty (RR 4.86, 95% CI 0.24 to 99.39, Analysis 4.4.1).

5. Treatment of UI after radical prostatectomy: post‐operative use of one treatment versus another active treatment (Comparison 5)

Nine trials comparing one active treatment to another were identified (Floratos 2002; Goode 2009; Hoffman 2005; Joseph 2000; Koo 2009; Moore 1999; Seleme 2008; Yokoyama 2004; Zhang 2007).

The quality of the evidence is given in summary of findings Table 4.

Number of incontinent men

Four small trials provided data for this outcome (Goode 2009; Moore 1999; Yokoyama 2004; Zhang 2007). The definition of incontinence varied with each trial:

There was no difference in the incontinence rates in the trials at any time period, but CIs were wide, up to 3 months (RR 0.96, 95% CI 0.83 to 1.12, Analysis 5.1); 3 to 6 months (RR 0.59, 95% CI 0.33 to 1.05, Analysis 5.2); 6 to 12 months (RR 2, 95% CI 0.21 to 18.23, Analysis 5.3) and the quality of evidence was deemed to be of very low quality.

Pad tests

For the majority of the comparisons there were no statistically significant differences between the groups, SDs were large, indicating skewed distribution of data, and the CIs were wide.

However, men having extra‐corporeal magnetic innervation (ExMI) compared to PFMT alone had less urine loss on the 24 hour pad test at 3 to 6 months in one small trial (Koo 2009) (compared to PFMT alone, MD ‐36 g, 95% CI ‐55 to ‐17, Analysis 5.12.3) and used fewer pads per day (MD ‐0.5, 95% CI ‐0.79 to ‐0.21, Analysis 5.13.1) (Koo 2009).

Quality of life

In another small trial (Seleme 2008) men receiving PFMT plus biofeedback plus ES reported better quality of life using the Incontinence Quality of life score than those receiving PFMT alone (MD ‐28.63, 95% CI ‐34.60 to ‐22.66, Analysis 5.6.1).

In a third trial (Liu 2008), PFMT supplemented by extra‐corporeal magnetic innervation (ExMI) seemed to be better than PFMT alone in terms of quality of life assessed using the ICIQ‐SF score (MD ‐1.60, 95% CI ‐2.73 to ‐0.47, Analysis 5.7.1) but the quality of the evidence for this outcome was judged to be of low quality.

Adverse events

Two men in one trial (Goode 2009) had an adverse event with ES (haemorrhoidal irritation, RR 5, 95% CI 0.24 to 102.30, Analysis 5.8.1) but the evidence for this outcome was judged to be of low quality.

Radical prostatectomy: prevention of UI in all men having surgery, intervention before or after prostatectomy or both

6. Prevention of UI after radical prostatectomy: PFMT ± biofeedback versus no treatment or sham therapy or verbal instruction (Comparison 6)

Ten trials addressed this comparison (Bales 2000; Burgio 2006; Filocamo 2005; Laurienzo 2013; Mathewson‐Chapman 97; Overgard 2008; Parekh 2003; Ribeiro 2008; Tienforti 2012; Tobia 2008). The quality of the evidence is given in summary of findings Table 5.

Differences between trials

The participants were not selected because they were incontinent so included a mixed population of men with and without incontinence after surgery.

Sources of heterogeneity

(1) The type of PFMT regimens differed between the trials:

Biofeedback was delivered via surface electrodes (Bales 2000) or via a digital or anal probe (Burgio 2006; Mathewson‐Chapman 97; Parekh 2003; Tienforti 2012). In one trial (Ribeiro 2008) the type of biofeedback was not described.

(2) Control interventions differed between the trials and included:

(3) The timing of the interventions relative to surgery also varied:

Number of men with UI

Data describing UI were reported by 8 of the 10 trials. While there was no statistically significant difference at 3 months (Analysis 6.1.1), there was evidence from the findings of this systematic review of an overall benefit from PFMT in the number of men with UI within 6 to 12 months (24% versus 52%, RR 0.51, 95% CI 0.35 to 0.75, Analysis 6.1.3) and after 1 year (10% versus 32%, RR 0.32, 95% CI 0.20 to 0.51, Analysis 6.1.4), but the quality of evidence was judged to be moderate. The data were driven mainly by two trials (Filocamo 2005; Overgard 2008), neither of which included biofeedback. One of these trials did not disclose details of allocation concealment (Filocamo 2005) and the other was small (Overgard 2008). The remaining trials showed conflicting results and there was statistically significant heterogeneity, hence the use of a random‐effects model.

Pad changes and pad tests

In the four trials which reported these outcomes (Filocamo 2005; Mathewson‐Chapman 97; Overgard 2008; Ribeiro 2008) there was statistical heterogeneity. One small trial favoured PFMT (Ribeiro 2008) but using a random‐effects model there was only a significant difference at 6 to 12 months (MD ‐15 g less urine loss on 24 hour pad test with treatment, 95% CI ‐18 to ‐11, Analysis 6.4.3). Men in the intervention group in this trial received PFMT plus biofeedback weekly for three months until they were continent or until three months. The findings from the Filocamo 2005 and Overgard 2008 trials (no significant difference in pad weights) was in contrast to their report of fewer incontinent men with active treatment (RR 0.32, 95% CI0.20 to 0.51, Analysis 6.1.4). However, the SDs were large and the CIs were wide. Laurienzo 2013 did not find a significant difference up to 12 months when using a 1 hour pad test (MD 19.80, 95% CI ‐9.15 to 48.75, Analysis 6.3) and comparing PFMT with no standard treatment.

Mean number of incontinence episodes per day

Tienforti 2012 favoured PFMT at all time points (MD ‐1.43, 95% CI ‐2.35 to ‐0.51, Analysis 6.5) when quantifying episodes of UI in men each day, with men in the intervention group suffering fewer mean numbers of episodes.

Quality of life

Quality of life was assessed using the ICIQ‐SF by two trials (Laurienzo 2013; Ribeiro 2008) but the quality of the evidence was found to be very low. No significant difference was found within 6 to 12 months (MD ‐0.69, 95% CI ‐3.19 to 1.81, Analysis 6.6).

Ribeiro 2008 also assessed quality of life using the IIQ, favouring the intervention at 3 to 6 months (MD ‐2.70, 95% CI ‐4.88 to ‐0.52, Analysis 6.7).

7. Prevention of UI after radical prostatectomy: electric or magnetic energy (for example anal ES (EStim), perineal ES, TENS, extra‐corporeal magnetic innervation (ExMI)) versus no treatment or sham treatment (Comparison 7)

One small trial that delivered the intervention pre‐operatively only was identified (Laurienzo 2013). There was no significant difference using a 1 hour pad test at 6 to 12 months (MD ‐1.15, 95% CI ‐9.11 to 6.81, Analysis 7.1) or when assessing quality of life using the ICIQ‐SF (MD 1.60, 95% CI ‐2.15 to 5.35, Analysis 7.2), but the quality of evidence for this outcome was judged to be very low (summary of findings Table 6).

8. Prevention of UI after radical prostatectomy: lifestyle interventions versus no treatment or sham treatment (Comparison 8)

No trials were identified.

9. Prevention of UI after radical prostatectomy: combinations of treatments versus no treatment or sham treatment (Comparison 9)

Only one small trial (Mariotti 2009) looked at this comparison. Men in the intervention group received PFMT plus ES with biofeedback post‐operatively and men in the control group received verbal and written instructions on PFMT. There was a statistical difference with regards to:

  • number of incontinent men within 6 to 12 months (RR 0.10, 95% CI 0.01 to 0.73, Analysis 9.2);

  • using a 24 hour pad test (MD ‐24.30, 95% CI ‐45.02 to ‐3.58, Analysis 9.4); and

  • time until UI was regained (MD ‐1.50, 95% CI ‐2.44 to ‐0.56, Analysis 9.5).

However, the quality of evidence for the primary outcome (number of incontinent men) was found to be low (summary of findings Table 7).

Adverse events

Adverse events were not reported.

10. Prevention of UI after radical prostatectomy: one treatment versus another active treatment (Comparison 10)

Eight trials were identified (Ahmed 2012; Centemero 2009; Dijkstra‐Eshuis 2013; Fode 2014; Geraerts 2013Nowak 2007; Park 2012; Wille 2003). Five of these were new in this update (Ahmed 2012; Dijkstra‐Eshuis 2013; Fode 2014; Geraerts 2013; Park 2012) and one was updated with new information (Centemero 2009).

  • Ahmed 2012 was a three‐armed trial, with patients receiving PFMT plus TENS with biofeedback or TENS only or guided PFMT only.

  • Centemero 2009 compared PFMT before and after surgery with PFMT delivered after surgery only.

  • Dijkstra‐Eshuis 2013 compared pre‐operative guided PFMT with biofeedback versus post‐operative written instructions on PFMT; however all men received PFMT plus biofeedback plus ES if they were still incontinent after six weeks.

  • Fode 2014 compared PFMT + penile vibration before and after surgery with PFMT alone before and after surgery: all men received a phosphodiesterase type 5 (PDE5) inhibitor after the first month.

  • Geraerts 2013 compared PFMT plus biofeedback versus active PFMT.

  • Nowak 2007 compared extra‐corporeal magnetic innervation (ExMI) versus PFMT alone but did not provide any useable data.

  • Park 2012 compared post‐operative PFMT plus general exercise versus post‐operative PFMT alone.

  • Wille 2003, a three‐arm trial, compared PFMT plus ES versus PFMT plus ES plus anal probe biofeedback versus PFMT alone.

The trials were generally small and few were similar enough to combine in a meta‐analysis. The quality of the evidence is illustrated in summary of findings Table 8.

Number of incontinent men

This outcome was reported by six trials (Ahmed 2012; Centemero 2009; Dijkstra‐Eshuis 2013; Fode 2014; Ghanem 2013; Park 2012).

In one trial, Centemero 2009 reported fewer incontinent men at less than 3 months and within 3 to 6 months when PFMT was delivered pre and post‐operatively, compared with post‐operatively only, and this correlated with a statistically significant better quality of life score (MD ‐3.70, 95% CI ‐6.00 to ‐1.40, Analysis 10.15.1; MD ‐4.10, 95% CI ‐6.64 to ‐1.56, Analysis 10.16.1). However, when combined with the data from Geraerts 2013, who used the same interventions, there was no statistically significant difference between the interventions at 3 months (RR 0.86, 0.69 to 1.06, Analysis 10.1.1) or 3 to 6 months (RR 0.75, 95% CI 0.54 to 1.04, Analysis 10.2.1). It should be noted that the CIs were very wide.

Ahmed 2012 compared three different treatments (PFMT plus transcutaneous electrical stimulation with biofeedback; TENS only; and guided PFMT only) and found no statistically significant differences between the interventions in terms of number of men with UI (Analysis 10.1, Analysis 10.2; Analysis 10.3) except that at 6 to 12 months PFMT plus ES plus biofeedback proved to be significantly better than PFMT only (RR 0.10, 95% CI 0.01 to 0.76, Analysis 10.3.3).

One small trial (Park 2012) found that general exercise added to PFMT was statistically significantly better than PFMT alone within 3 to 6 months (RR 0.48, 95% CI 0.23 to 0.99, Analysis 10.2.3).

Four trials reported the number of incontinent men after 12 months (Dijkstra‐Eshuis 2013;Fode 2014;Geraerts 2013;Ghanem 2013). The quality of the evidence was moderate (summary of findings Table 8). Three of these trials, comparing pre and post‐operative PFMT to post‐operative PFMT only, found that more men were incontinent after 12 months when PFMT began before surgery (15.3% versus 10.7% with post‐operative training alone) but this did not reach statistical significance (RR 1.32, 95% CI 0.78 to 2.25, Analysis 10.4.1). The Fode 2014 study was too small to identify a difference between PFMT plus penile vibratory stimulation pre and post‐operatively compared with pre and post‐operative PFMT (Analysis 10.4.2).

Pad tests

In general, the short‐duration pad tests did not distinguish between the various interventions being compared, apart from in one trial. At 6 months (but not at 3 months), Wille 2003 found that PFMT plus anal ES both with and without extra biofeedback were both better than PFMT alone using a 20 minute pad test (MD urine lost ‐3 g, 95% CI ‐6 to ‐0.5 in both comparisons, Analysis 10.8.1 and Analysis 10.8.2), while there was little to choose between the two more intensive interventions (Analysis 10.8.3). However, the trial was small, the SDs large and the CIs wide.

Using a longer‐duration 24 hour pad test, the groups receiving ES were generally better than those only having PFMT or only having ES (Analysis 10.12; Analysis 10.13; Analysis 10.14) but the interventions were to dissimilar to combine. At three to six months, one small trial (Park 2012) did not find significant benefit when comparing PFMT plus general exercise with PFMT alone (Analysis 10.13.4).

Quality of life
ICIQ‐SF

The ICIQ‐SF score is a mixed measure of both incontinence severity and effect on quality of life. One small trial (Park 2012) found that there was a significant benefit in terms of the ICIQ‐SF and the intervention PFMT plus general exercise versus PFMT alone, but the evidence for this outcome was found to be very low (MD in scores ‐4.00, 95% CI ‐5.41 to ‐2.59, Analysis 10.16.2).

King’s Health Questionnaire

For all domains of the King’s Health Questionnaire, Dijkstra‐Eshuis 2013 did not find a statistically significant difference between PFMT given pre and post‐operatively and PFMT given post‐operatively only (Analysis 10.18).

SF‐36

In contrast, one trial (Park 2012) found that the intervention PFMT with general exercise was favoured at 3 to 6 months when using the health status measure SF‐36 (MD ‐9.00, 95% CI ‐11.17 to ‐6.83, Analysis 10.19.1) compared with PFMT alone. This may have been more of a measure of an effect of exercise on general health than on incontinence itself.

Adverse events

One trial (Fode 2014) was in the meta‐analysis and the authors stated that 5/30 men reported adverse effects in the intervention group using the group with a penile vibratory stimulation device. The quality of evidence for this outcome was deemed to be low. Adverse effects included:

  • red spots on the glans penis;

  • small laceration with some bleeding;

  • soreness;

  • frank pain.

TURP: treatment of incontinent men, after surgery

11. Treatment of UI after TURP: PFMT ± biofeedback versus no treatment or sham therapy or verbal instruction (Comparison 11)

One large trial compared PFMT with or without biofeedback to no treatment (sham or verbal instruction) amongst men who had UI after TURP (Glazener TURP 2011). All the men were incontinent at randomisation, six weeks after surgery, and received four one‐to‐one sessions with a trained therapist over a three month period. The quality of the evidence is illustrated in summary of findings Table 11.

Incontinence in men and incontinence episodes

There were no significant differences at any time period in the incontinence rates (for example RR for incontinence up to 12 months 1.04, 95% CI 0.90 to 1.20, Analysis 11.1.3; and after 12 months, 65% with UI versus 62% in the control group, RR 1.05, 95% CI 0.91 to 1.23, Analysis 11.1.4). The evidence was judged to be moderate.

In one large trial (Glazener TURP 2011) men did not report differences in incontinence episodes at any time period, based on urinary diary data (for example after 12 months MD 0.2, 95% CI ‐0.27 to 0.67, Analysis 11.2).

Use of pads

Use of pads could be considered to be a measure of more severe incontinence. There was no statistically significant difference in the number of men using pads in one large trial (16% in intervention group versus 18% in control group after 12 months, RR 0.93, 95% CI 0.56 to 1.56, Analysis 11.3) (Glazener TURP 2011).

Urinary incontinence score and effect on quality of life

In one large trial (Glazener TURP 2011), there was no evidence of a difference in the ICIQ‐SF (a composite score of frequency, amount and effect of UI on quality of life) at any time period after the intervention up to or beyond one year (for example MD after 12 months ‐0.1, 95% CI ‐0.89 to 0.69, Analysis 11.4) or quality of life as a single score from 0 to 10 (MD ‐0.1, 95% CI ‐0.51 to 0.31, Analysis 11.5). The quality of evidence for this outcome was deemed to be low.

Adverse events

No adverse events were reported.

TURP: prevention of UI in all men having surgery, intervention before or after prostatectomy, or both

16. Prevention of UI after TURP: pre or post‐operative PFMT ± biofeedback versus no treatment or sham therapy or verbal instruction (Comparison 16)

Three small trials enrolled men before TURP for benign prostatic hyperplasia (Hou 2013; Porru 2001; Tibaek 2007). Men in the intervention groups in both trials received one session with a therapist before surgery to teach them the correct contractions (using verbal biofeedback) and they were expected to practice PFMT afterwards. In the second trial (Tibaek 2007), men also attended three group teaching sessions. The control groups received information only. The quality of the evidence is illustrated in summary of findings Table 12.

There were no statistically significant differences between the groups in the number of men with incontinence at less than 3 months or 3 to 6 months, but the CIs were wide and the quality of evidence was very low (< 3 months RR 0.60, 95% CI 0.21 to 1.77, Analysis 16.1.1; 3 to 6 months RR 0.51, 95% CI 0.14 to 1.89, Analysis 16.1.2).

Quality of life

One trial (Hou 2013) measured quality of life using a health status measure Short‐Form 36 (SF‐36) questionnaire at three to six months. No statistically significant differences were found on any of the domains apart from those associated with mental health (Analysis 16.2).

Containment of UI (all men with residual UI)

21. External penile compression devices (penile clamps) versus no treatment or sham treatment (Comparison 21)

One trial compared three different penile compression devices (Cunningham clamp, U‐Tex Male Adjustable Tension Band, and C3 penile compression device) with a control period of no device (Moore 2004). A randomised block assignment was used with a multiple period cross‐over design, so that each of the 12 participants had a control period of no device and three periods in which the different devices were used.

All external compression devices reduced the weight of urine lost on a four hour pad test compared to the control period (P < 0.05, Analysis 21.2), but none completely eliminated urine loss. Satisfaction was based on ease of application, comfort and efficacy. The device preferred by the largest number of men (Analysis 21.1) was also that with the lowest urine loss (the Cunningham clamp) (Analysis 21.2).

Adverse events

The Cunningham clamp was also the device with the greatest reduction in systolic blood flow velocity (P < 0.05 versus control period, Analysis 21.3; Analysis 21.4), raising the possibility of safety issues if applied too tightly. In the trial, men were able to judge when to release the device. The authors recommended that its use should therefore be limited to men who were cognitively intact, aware of bladder filling, had normal genital sensation and intact penile skin, and had sufficient manual dexterity to open and close the device (Moore 2004).

In another trial with no useable data (Fader 2013), men provided qualitative information which suggested that pads were most highly rated compared with sheath catheters (P = 0.31), clamps (P < 0.01) and the body‐worn urinal (P < 0.001). The clamp was rated as more secure, less leaky and less restrictive on clothing choice than the others (P < 0.05) but was more painful than the rest (P < 0.002).

Discussion

This review incorporates a broad array of possible interventions under the umbrella term of conservative management of postprostatectomy UI. The populations studied included men undergoing prostatectomy for both benign (TURP) and malignant (radical prostatectomy) disease. The interventions were delivered pre‐operatively, post‐operatively or both. In some trials all the men were incontinent at baseline, while at least some were dry in other trials which recruited all men having surgery (these were classed as prevention of incontinence trials). Seven trials (Goode 2009; Joseph 2000; Moore 1999; Moore 2004; Opsomer 1994; Seleme 2008; Zhang 2007) included men who had been incontinent for a considerable time after surgery while the rest recruited men around the time of surgery. More recent trials have focused on the pre‐operative or post‐operative period immediately after catheter removal. It is acknowledged that UI after prostatectomy will resolve over time in many men.

Conservative interventions tend to be resource‐intensive strategies that require people, equipment and clinic space, so administrators will look for evidence of efficacy. Funding has been an issue given the inconclusive nature of the evidence to date. For example, in the United States, the centres for both Medicare and Medicaid services have considered whether to withdraw funding for biofeedback and pelvic floor electrical stimulation (ES) in the treatment of UI of any etiology based on a lack of evidence regarding effectiveness. Through a lobbying effort from service providers and manufacturers, these modalities continued to be covered in the United States (Thompson 2002). However, as controversy about funding is likely to continue, there is a need for continued research in the area to determine which groups of patients are most likely to benefit from conservative interventions.

The findings of this review should continue to be treated with caution. The effectiveness of conservative measures in the longer term or in men with persistent UI remain inconclusive.

Summary of main results

Fifty trials met the inclusion criteria, 45 trials amongst men after radical prostatectomy, four trials after TURP, and one small trial which included one man with benign disease but was classed as a radical prostatectomy trial. There was considerable variation in the interventions, populations and outcome measures. Given this clinical heterogeneity it was decided to differentiate the trials and the comparisons, by type of surgery (TURP or radical prostatectomy) and by whether the intervention was partly preventative (in that not all men were incontinent, for example if all men before or after surgery were recruited, N = 27 trials), for treatment only (when all included men were incontinent at baseline, N = 23 trials) or for containment (external penile compression devices, N = 2 trials). Although the International Prostate Score (IPSS) was used in many of the trials, the authors felt that this questionnaire did not assess UI and therefore was not included in the outcome of quality of life.

Treatment trials for urinary incontinence after radical prostatectomy

Twenty‐one trials investigated the effects of PFMT versus no treatment or a variety of other means of stimulating the pelvic floor muscles. There was considerable clinical and statistical heterogeneity in the populations and the timing and frequency of the interventions, hence a random‐effects model was chosen for most of the comparisons where meta‐analysis was possible. Only two trials (Manassero 2007; van Kampen 1998) showed a statistically significant benefit from active treatment versus no treatment control groups (at 12 months and within 6 to 12 months respectively), and the other trials showed conflicting results. There was differential dropout from the control group in the Manassero 2007 trial (these men were assumed to be dry for analysis purposes). Additionally, men in the experimental group in the van Kampen 1998 trial received one session of PFMT in hospital before discharge and were then seen by a physiotherapist for one to two weeks, whereas those in the Manassero 2007 trial were taught PFMT by two urologists using verbal feedback and instructed to perform contractions at home. Because of the heterogeneity a random‐effects model was used, which led to wider confidence intervals (CIs).

Overall, there was not enough evidence to say whether or not PFMT with or without biofeedback was effective as the CIs were wide (for example number of men with incontinence in the intervention groups 193/339 (57%) versus 203/326 (62%) in the control groups, RR for incontinence after 12 months 0.85, 95% CI 0.60 to 1.22, Analysis 1.1.4).

The meta‐analysis was dominated by the Glazener RP 2011 trial, which was a large pragmatic multi‐centre trial conducted in a context where information on PFMT was widely available. This showed no good evidence to support one‐to‐one training by a therapist (for example RR for UI after 12 months 0.98, 95% CI 0.87 to 1.09, Analysis 1.1.4) (Glazener RP 2011). This one large trial had narrow CIswhich did not include a clinically significant difference, pre‐specified to be 15%. The only other large trial (Moore 2008) was in line with the Glazener RP 2011 findings but with wider CIs (RR 1.02, 95% CI 0.70 to 1.48, Analysis 1.1.4) (Moore 2008) despite a more intensive intervention. While men in the Glazener RP 2011 trial had four therapy sessions over three months, in the Moore 2008 trial men were seen weekly for up to six months. The findings in these two trials concurred despite different intensities of intervention, and the quality of evidence for this GRADE‐specific outcome was moderate. Data from quality of life measures and use of pads and pad tests supported the finding of no differences between intervention and control groups.

Three small trials provided data and the meta‐analysis suggested that ES was better than control interventions in terms of less incontinence, regaining continence more quickly and better quality of life, at least in the short term up to six months. The quality of evidence was deemed to be moderate, however less information was available for the longer term.

Individual small trials provided data to suggest that extra‐corporeal magnetic innervation (ExMI) or combinations of treatments might be beneficial but the evidence was limited.

Prevention trials for urinary incontinence after radical prostatectomy

Nineteen trials, some of which enrolled men before surgery and others all men as soon as the catheter was removed, included a mixed population of men with and without incontinence after surgery. Again a random‐effects model was chosen to compensate for the considerable clinical and statistical heterogeneity between the trials. Including the information from the quasi‐randomised trial (Filocamo 2005), the chance of incontinence appeared to be lower in the intervention groups in two trials with data after 12 months. The quality of evidence was judged to be moderate (number of men with UI after one year 10.2% versus 32.1% in the control groups, RR 0.32, 95% 0.20 to 0.51, Analysis 6.1.4).

The meta‐analysis of prevention trials included a number of small trials with wide CIs apart from Filocamo 2005, which was out of line with the others. This was the only large trial to favour the intervention group. The worry is that this trial may have been biased due to a lack of reporting on concealment of allocation.

One small trial (Ribeiro 2008) suggested that men were more likely to be carrying out PFMT, at least soon after the intervention (Analysis 6.9), though this was not reflected in significant differences in higher anal squeeze pressures (Analysis 6.8). Another trial of anal ES was too small to be conclusive (Laurienzo 2013). One small trial (Mariotti 2009) reported that adding anal ES and biofeedback to PFMT was beneficial. One further small trial (Wille 2003) found that PFMT plus anal ES with and without extra biofeedback were both better than PFMT alone at six months, but there was little to choose between the two more intensive interventions (Analysis 10.8). Tienforti 2012 found that pre‐operative PFMT was associated with a reduction in number of incontinence episodes per day, but this was a small trial and larger sample sizes would be needed to draw reliable conclusions.

Nine trials compared one active treatment with another active treatment. Overall there did not seem to be one intervention that proved to be statistically significantly better than another.

Treatment trials for urinary incontinence after TURP

One large trial addressed this comparison (Glazener TURP 2011), comparing four sessions of one‐to‐one therapy with standard management in a context where information about PFMT was widely available. The quality of evidence for the number of incontinent men was moderate but there were no differences between the groups in any of the outcome measures except for performance of PFMT, suggesting that the intervention had changed behaviour but not incontinence or other clinical outcomes.

Prevention trials for urinary incontinence after TURP

Three small trials enrolled men before TURP to receive a minimal PFMT intervention before and after surgery. There were no statistically significant differences in terms of number of incontinent men between the groups but the quality of evidence was deemed to be very low (Analysis 16.1).

Containment of urinary incontinence

One alternative intervention, a clamp fitted to the shaft of the penis, can be used to control unwanted leakage. Men in one trial reported a preference for one type of external compression device compared to two others or no treatment; a Cunningham clamp proved satisfactory to 10 of 12 men with intractable UI (Moore 2004). This may be a viable alternative for some cognitively capable men providing they take into account safety issues such as adequate sensation and the ability to remove the device when it feels too tight or the bladder is full. Another trial which compared pads, sheath catheters, body‐worn urinals and clamps also reported that men found the clamps most effective but painful (Fader 2013).

Men whose incontinence cannot be otherwise controlled can use absorbent pads (Fader 2007; Fader 2008) or a variety of external sheath devices with leg bags. An alternative is an indwelling urinary catheter (Jahn 2007; Moore 2007; Niël‐Weise 2005).

Lifestyle changes

The effect of other conservative interventions such as lifestyle changes remains undetermined as no trials involving these interventions were identified.

Overall completeness and applicability of evidence

Few trials used the primary outcomes of interest, patient reported symptoms and the standardised pad test. Most used a variety of subjective outcomes derived from patient reported symptoms to define continence. There were no trials which examined lifestyle adjustments in alleviating UI after prostatectomy.

Attrition bias may have played a role in the results of some of the included trials and therefore affected the outcome of this review. One of the smaller trials (Franke 1998) lost half of the randomised participants by the end of the data collection period. Although most of those trials that lost participants provided an explanation of these losses, none accounted for the missing data in their primary analyses. The intention‐to‐treat principle mandates, at minimum, that patients stay in the group to which they are randomised (Juni 2001), which the included trials appeared to do. It is also suggested that primary outcomes for all patients randomised to groups should be recorded or estimated if not available. Three of the included trials (Filocamo 2005; Moore 2008; Parekh 2003) reported an analysis using the intention‐to‐treat principle, and one trial (Burgio 2006) used survivor analysis in the original trial analysis. In one trial where there was clear evidence of differential dropout (Manassero 2007), the review authors elected to assume that the men whose data were missing were continent. However, attrition bias may have affected a number of the other trials which did not present relevant data or discuss the issue.

In 21 trials in this review, men who were all incontinent were analysed together. However, in seven of these trials (Goode 2009; Joseph 2000; Moore 1999; Moore 2004; Opsomer 1994; Seleme 2008; Zhang 2007) men had longstanding or persistent incontinence. It is possible that they might respond differently to the interventions compared to men recruited around the time of prostate surgery.

Quality of the evidence

Trial quality and methodological assessment

The quality of the estimated treatment effect of any intervention is determined partly by methodological assessment. Methodological flaws within the included trials of this review were assessed using the reports of the trials and therefore were reliant on the quality of reporting. Data were not available in all the trials for many of the pre‐stated outcomes. CIs tended to be wide except for the more recent large trials, and it was difficult to reliably identify or rule out a useful effect.

All trials claimed to be randomised, but only 24 out of 50 trials provided details of adequate sequence generation (Ahmed 2012; Burgio 2006; Centemero 2009; Dijkstra‐Eshuis 2013; Dubbelman 2004; Filocamo 2005; Fode 2014; Glazener RP 2011; Glazener TURP 2011; Goode 2009; Laurienzo 2013; Manassero 2007; Mathewson‐Chapman 97; Moore 1999; Moore 2004; Moore 2008; Overgard 2008; Park 2012; Robinson 2008; Robinson 2009; Tibaek 2007; Tienforti 2012; van Kampen 1998; Yamanishi 2006). Only 20 of the 50 trials provided details of adequate concealment of randomisation (Ahmed 2012; Burgio 2006; Centemero 2009; Dijkstra‐Eshuis 2013; Dubbelman 2004; Fode 2014; Geraerts 2013; Glazener RP 2011; Glazener TURP 2011; Goode 2009; Manassero 2007; Moore 1999; Moore 2004; Moore 2008; Overgard 2008; Park 2012; Robinson 2008; Tibaek 2007; van Kampen 1998; Yamanishi 2006) and were subsequently judged to be at low risk of selection bias. Additionally, blinding to PFMT was not possible, and blinding of outcome assessment appeared to be absent in many trials as it was not discussed. Therefore, many trials were judged to be at high risk of performance and detection bias.

The quality of the evidence was downgraded for the following.

  • Study design i.e. there was evidence of methodological flaws in the study design.

  • Indirectness i.e. a surrogate outcome was selected when a GRADE‐specific outcome was not reported.

  • Inconsistency, when there was evidence of statistical (either clinical or methodological) heterogeneity.

  • Imprecision, when the CIwas wide and crossed the line of no effect.

  • Publication bias. We planned to use funnel plot for publication bias, however, there were fewer than 10 trials in the meta‐analysis and the funnel plot could not be used.

The quality of the evidence for the critical outcomes ranged from moderate to very low, as evident in the summary of findings tables.

Potential biases in the review process

All relevant databases were searched and no language restriction was imposed during the search process, which enabled as many potentially eligible trials as possible to be included. Some reports of trials may not be published and therefore the full extent of the data may not have been obtained. One of the review authors was involved in four of the included trials and another review author was involved in two of the included trials. In order to account for this potential bias in the review process, data extraction and risk of bias assessment were performed by two independent review authors, one of whom was not involved in any of the included trials.

Agreements and disagreements with other studies or reviews

A systematic review conducted by Macdonald et al (MacDonald 2007) was identified which addressed conservative management of post‐prostatectomy urinary incontinence. Macdonald and colleagues included 11 trials (Bales 2000; Burgio 2006; Filocamo 2005; Floratos 2002; Franke 1998; Mathewson‐Chapman 97; Moore 1999; Parekh 2003; van Kampen 1998; Wille 2003; Yokoyama 2004), all of which were included in this review. They did not distinguish between treatment and prevention trials. Macdonald and colleagues' review analysed PFMT and PFMT with biofeedback, focusing on any additional benefit from biofeedback. The authors concluded that the use of guided PFMT was associated with superior patient outcomes compared with no treatment, which differs from the findings of this review. The Macdonald and colleagues review did not include more recent trials because the MEDLINE search only included trials up to 2006. Additionally, the conclusions made in Macdonald's review may have differed because the authors did not utilise the GRADE approach, suggesting the quality of the evidence was not assessed.

Intervention

Control

Ahmed 2012

A: At catheter removal received standard care of verbal and written instructions, instructed by physiotherapist to perform 3 sets of 15‐20 contractions daily, for a duration of 3‐5 seconds with a 6‐10 second rest period, encouraged to perform exercises before functional activities such as sneezing, coughing, or lifting weight, also in the supine position, sitting, squatting and going up and down stairs

 

B: ES, treatment started one week after catheter removal, patients received 15 minutes of twice weekly electrical stimulation for 12 weeks

 

C: PFMT + BFB + ES: Treatment started one week after catheter removal, patients received twice weekly treatment with 15 minutes of electrical stimulation and 15 minutes of biofeedback for 12 weeks, instructed to perform 3 series of 10 rapid contractions, 3 sustained contractions of 5, 7 or 10 seconds and then 10 contractions during prolonged expiration in the supine position

 

All patients were given a logbook to complete daily regarding self‐report of exercises   

Bales 2000

PFMT + biofeedback

45 minute session with nurse trained in biofeedback. Patients were instructed to perform graded PFMT. Contractions of 5‐10 seconds, 10‐15 repetitions were performed with biofeedback (surface electrodes used to measure muscle strength). Advised to practice the exercises 4 times per day until surgery

No biofeedback training

Written and brief verbal instructions from a nurse on how to perform PFMT (isolate muscle that stops urine flow, practice 4 times per day, 10‐15 repetitions).

Burgio 2006

PFMT + biofeedback

Single session of biofeedback (rectal probe to measure intra‐abdominal rectal pressure and external anal sphincter contraction) assisted behavioural training. Feedback and verbal instruction used to teach control of pelvic muscles. Taught to contract sphincter during 2‐10 seconds periods separated by 2‐10 seconds of relaxation, dependent on ability.

Written instructions for daily at home practice of 45 PFM exercises daily (3 sessions of 15 exercises each time). Additionally instructed to slow or interrupt voiding once daily. Encouraged to exercise daily preoperatively, then resume when catheter removed post‐operatively

Usual care of brief verbal instructions post operatively to interrupt the voiding stream plus any instruction from physician.

Centemero 2009

Intervention A: PFMT both pre and post‐operatively. A structured PFMT program 30 and 15 days before surgery, previous physiotherapist evaluation to provide the patients with feedback about the quality of pelvic floor muscle function, PC teste (endurance and contraction quality), breathing coordination, typify muscle contraction as tonic and modify incorrect physical attitudes. This was also repeated after the procedure

Intervention B: PFMT post‐operatively only

Dijkstra‐Eshuis 2013

30 mins of guided PFMT + biofeedback weekly for 4 weeks before surgery, received written instructions to: carry out two sets of 30 contractions during abdominal breathing, one breath between each contraction; restart PFMT after catheter removal (7‐10 days after surgery)

All men were seen before surgery by a physiotherapist, who explained relevant anatomy, anal visual inspection and digital palpation, biofeedback registration with rectal probe, All patients received PFMT + biofeedback or electrical stimulation, or both, if still incontinent after 6 weeks

Received written instructions on PFMT after catheter removal (7‐10 days after surgery)

Dubbelman 2004

Nine or less sessions of physiotherapy guided pelvic floor exercises after surgery

Exercise instruction through information folder

Filocamo 2005

Formal instruction (3 treatment sessions plus at home exercises) in PFMT using verbal explanation, palpation and visualization of the base of the penis with a mirror, in different positions and prior to sneezing, coughing or lifting

No formal instruction

Floratos 2002

Initiated after catheter removal, 15 treatment sessions (3 times per week for 30 minutes) of PFMT with EMG (surface) biofeedback in clinic

Instruction with verbal feedback and an information pamphlet with instructions to perform PFMT 50‐100 times daily at home

Fode 2014

Pre‐operative session guided PFMT + instruction on how to use penile vibratory stimulation device. Instructed to stimulate frenulum once daily, 10 seconds of stimulation then 10 second pause, repeated 10 times for 1 week pre‐operatively, instructed to restart stimulation after catheter removal for 6 weeks

All men were offered a PDE5 inhibitor after 1 month post‐operatively and also received telephone contact to ensure compliance with treatment 

Preoperative session guided PFMT

Franke 1998

Biofeedback (perineal patch EMG) enhanced PFMT; exercise treatment sessions at 6, 7, 9, 11, and 16 weeks post‐operatively

No treatment.

Geraerts 2013

Intervention A: PFMT + biofeedback

30 mins of guided PFMT + biofeedback weekly for 3 weeks before surgery. Patients were instructed to carry out 60 contractions a day at home; contract their pelvic floor while coughing, and sitting down or getting up from a chair. Patients were also instructed to restart PFMT on day 4 after surgery while catheter was in situ

Intervention B: Instructed to start PFMT on the day after catheter removal (e.g. 2‐3 weeks after surgery)

All men: Received weekly individual guided exercise programme with digital or EMG biofeedback after surgery. Advice was given on how to contract pelvic floor muscles to prevent leakage during functional activities. When patients carried out the instructed 60 contractions, they were asked to colour in three squares in their diary to assess compliance

Ghanem 2013

Pre‐operative PFMT for 2 weeks + postoperative PFMT programme      

Postoperative PFMT programme only

Goode 2009

Intervention A: Behavioural therapy with PFMT for 8 weeks

Intervention B: Behavioural therapy with biofeedback and electrical stimulation for 8 weeks

Behavioural therapy consisted of pelvic floor muscle exercises and bladder control strategies in both groups

No treatment

Hoffman 2005

Intervention A: perineal EStim plus physiotherapy (PFMT)

Intervention B: anal EStim plus physiotherapy (PFMT)

PFMT alone

Hou 2013

Guided PFMT + biofeedback after catheter removal (2 days post‐operatively), instructed to: contract pelvic muscles for 5 seconds and relax for 10 seconds. After discharge, patients were instructed to carry out 5 mins of each PFE three times daily. Patients also received motivational telephone interviews once weekly

No description

Joseph 2000

Intervention A: Instruction in PFMT including biofeedback with visual feedback as well as verbal to assist in identifying and discriminating muscles

Intervention B: Instruction in PFMT, squeezing of finger during digital rectal examination

Koo 2009

Manassero 2007

PFMT re‐education program, verbal feedback

The training program involved active PFE. verbal feedback of the contraction was used to instruct the patients to correctly and selectively contract their pelvic muscles while relaxing the abdominal muscles. the strength of the pelvic floor muscles was measured by digital anal control using a score of 0 to 5 ( 0 = no contraction, 5 = good contraction against strong resistance)

Initially home practice comprised 45 contractions (3 sessions of 15) per day at home, progressively increasing the number until 90 per day. This was taught by two experienced urologists

No treatment.
