Urinary incontinence in men after formal one-to-one pelvic-floor muscle training following radical prostatectomy or transurethral resection of the prostate (MAPS): two parallel randomised controlled trials

Exploring the Hidden Struggles: A Qualitative Insight into Urinary Incontinence Among Prostate Cancer Survivors Post-Surgery

Objective

This study aimed to explore the experiences and challenges of prostate cancer patients suffering from urinary incontinence following radical prostatectomy.

Methods

A descriptive qualitative research design was employed. Purposeful sampling was used to select 22 prostate cancer patients who underwent radical prostatectomy and experienced urinary incontinence after surgery. These patients were interviewed between August to October 2023 at a tertiary B-grade hospital's pelvic floor center in Shanghai. The data were collected through semi-structured in-depth interviews and analyzed using content analysis to identify and refine themes.

Results

The experiences of urinary incontinence in patients can be categorized into four main themes: (1) Daily life disturbances (including 4 sub-themes: sleep disorders, fluid intake restriction, travel inconvenience, loss of sexual life); (2) Negative emotional experiences (including 4 sub-themes: perceived discrimination, concerns about recovery, loss of confidence in life, doubts about the surgical decision); (3) Social withdrawal (including 2 sub-themes: reduced desire for social interaction, decreased ability to socialize); (4) Limited support obtained (including 4 sub-themes: reliance on personal experience, seeking help from relatives and friends, difficulty discerning online information, lack of professional guidance).

Conclusion

Postoperative urinary incontinence in prostate cancer patients presents a multidimensional experience. Healthcare professionals need to pay attention to these patients' daily life, psychological state, and social interactions. Integrating various resources to provide professional support and rehabilitation guidance is crucial.

Urinary incontinence rehabilitation of after radical prostatectomy: a systematic review and network meta-analysis

Purpose

The aim of this study is to provide treatment for patients with urinary incontinence at different periods after radical prostatectomy.

Methods

The PubMed, Embase, Cochrane, and Web of Science were searched for all literature on the effectiveness on urinary control after radical prostate cancer between the date of database creation and 15 November 2023 and performed a quality assessment. A network meta-analysis was performed using RevMan 5.3 and Stata 17.0 software and evaluated using the surface under the cumulative ranking curve.

Results

The results of the network meta-analysis showed that pelvic floor muscle therapy including biofeedback with professional therapist-guided treatment demonstrated better results at 1 month to 6 months; electrical stimulation, biofeedback, and professional therapist guidance may be more effective at 3 months of treatment; professional therapist-guided recovery may be less effective at 6 months of treatment; and combined therapy demonstrated better results at 1 year of treatment. During the course of treatment, biofeedback with professional therapist-guided treatment may have significant therapeutic effects in the short term after surgery, but, in the long term, the combination of multiple treatments (pelvic floor muscle training+ routine care + biofeedback + professional therapist-guided treatment + electrical nerve stimulation therapy) may address cases of urinary incontinence that remain unrecovered long after surgery.

Conclusion

In general, all treatment methods improve the different stages of functional recovery of the pelvic floor muscles. However, in the long term, there are no significant differences between the treatments. Given the cost-effectiveness, pelvic floor muscle training + routine care + biofeedback + professional therapist-guided treatment + electrical nerve stimulation therapy within 3 months and pelvic floor muscle + routine care after 3 months may be a more economical option to treat urinary incontinence.

Assessing the efficacy of pelvic floor muscle training and duloxetine on urinary continence recovery following radical prostatectomy: A randomized clinical trial

BACKGROUND

Urinary incontinence (UI) can negatively impact quality of life (QoL) after robot-assisted radical prostatectomy (RARP). Pelvic floor muscle training (PFMT) and duloxetine are used to manage post-RARP UI, but their efficacy remains uncertain. We aimed to investigate the efficacy of PFMT and duloxetine in promoting urinary continence recovery (UCR) after RARP.

METHODS

A randomized controlled trial involving patients with urine leakage after RARP from May 2015 to February 2018. Patients were randomized into 1 of 4 arms: (1) PFMT-biofeedback, (2) duloxetine, (3) combined PFMT-biofeedback and duloxetine, (4) control arm. PFMT consisted of pelvic muscle exercises conducted with electromyographic feedback weekly, for 3 months. Oral duloxetine was administered at bedtime for 3 months. The primary outcome was prevalence of continence at 6 months, defined as using ≤1 security pad. Urinary symptoms and QoL were assessed by using a visual analogue scale, and validated questionnaires.

RESULTS

From the 240 patients included in the trial, 89% of patients completed 1 year of follow-up. Treatment compliance was observed in 88% (92/105) of patients receiving duloxetine, and in 97% (104/107) of patients scheduled to PFMT-biofeedback sessions. In the control group 96% of patients had achieved continence at 6 months, compared with 90% (p = 0.3) in the PMFT-biofeedback, 73% (p = 0.008) in the duloxetine, and 69% (p = 0.003) in the combined treatment arm. At 6 months, QoL was classified as uncomfortable or worse in 17% of patients in the control group, compared with 44% (p = 0.01), 45% (p = 0.008), and 34% (p = 0.07), respectively. Complete preservation of neurovascular bundles (NVB) (OR: 2.95; p = 0.048) was the only perioperative intervention found to improve early UCR.

CONCLUSIONS

PFMT-biofeedback and duloxetine demonstrated limited impact in improving UCR after RP. Diligent NVB preservation, along with preoperative patient and disease characteristics, are the primary determinants for early UCR.

Non-pharmacological and nonsurgical interventions in male urinary incontinence: A scoping review

AIMS

To describe and synthesize non-pharmacological and nonsurgical interventions for male urinary incontinence from the existing literature.

METHODS

A scoping review was conducted following the methodology suggested by Arksey and O'Malley: (1) identification of the research questions; (2) identification of relevant studies using a three-step search recommended by JBI: an initial search within PubMed and CINAHL, a comprehensive literature search within PubMed, CINAHL, EMBASE, PsycINFO, Cochrane Library, and literature search of references lists; (3) study selection; (4) data extraction and charting; (5) collation, summarization, and reporting of the results. The PRISMA-ScR Checklist was used to report.

RESULTS

A total of 4602 studies were identified, of which 87 studies were included. Approximately 78% were randomized controlled trials. More than 88% of the participants were men with prostate cancer. Exercising pelvic floor muscles 30 times per day for 12 weeks was the most frequently reported. Parameters of electrical stimulation were typically set up to 50 Hz and 300 μs for frequency and width of pulse, respectively, and lasted for 15 min. Pure pelvic floor muscle training, Pilates, Yoga, whole body vibration, diaphragm/abdominal muscle training, micturition interruption exercise, acupuncture, and auriculotherapy showed positive effects on reducing urinary incontinence.

CONCLUSION

The findings suggested implementing pelvic floor muscle training alone before or after surgery can both prompt the recovery of continence in men after prostate cancer surgery. The decision to use biofeedback or electrical stimulation to enhance the therapeutic effect of pelvic floor muscle training should be approached with caution. More rigorous designed studies are needed to validate the effectiveness of Traditional Chinese Medicine techniques and diverse novel methods.

RELEVANCE TO CLINICAL PRACTICE

Physicians and nurses need to be up to date on the latest evidence-based non-pharmacological and nonsurgical interventions in male urinary incontinence and select appropriate interventions based on available medical resources and patient preferences.

Pelvic floor muscle exercise with or without duloxetine for postprostatectomy urinary incontinence: A retrospective single-center study

This study aimed to evaluate the effectiveness of combined pelvic floor muscle exercise (PFME) and duloxetine treatment in the recovery from postprostatectomy urinary incontinence (PPUI). Participants were patients who underwent radical prostatectomy (RP) between 2018 and 2021 and who were able to attend follow-up appointments every 3 months for at least 12 months. Continence was defined as the use of ≤1 pad per day. PPUI was compared at each follow-up period by dividing the participants into the PFME group (PFME only after RP) and the PFME + DUL group (PFME and 30 mg duloxetine daily after RP). A total of 197 patients were included. No significant differences were observed in the baseline characteristics between the 2 groups. In the PFME group (n = 127), the PPUI was 77.17%, 27.56%, 17.32%, 12.60%, and 9.45% at 2 weeks, 3 months, 6 months, 9 months, and 12 months, respectively. In the PFME + DUL group (n = 70), the PPUI was 62.50%, 17.86%, 12.50%, 8.93%, and 5.36%, respectively, at the same follow-up period. At 2 weeks, the PFME + DUL group demonstrated a better incontinence rate than the PFME group (P = .019). However, no significant differences were found in the incontinence rates between the 2 groups at each follow-up period after 3 months. Compared to PFME monotherapy, the combination therapy of PFME and duloxetine has short-term effectiveness in improving PPUI, but it does not have a significant long-term impact. Therefore, for early recovery from PPUI, duloxetine should be administered for a short period during PFME.

The effect of perioperative pelvic floor muscle exercise on urinary incontinence after radical prostatectomy: a meta-analysis

BACKGROUND

Pelvic floor muscle exercise (PFME) is the most common conservative management for urinary incontinence (UI) after radical prostatectomy (RP). We performed this meta-analysis to investigate whether PFME during the entire perioperative period, including before and after RP, can significantly improve the recovery of postoperative UI.

METHODS

We systematically reviewed randomized controlled trials (RCT) from PubMed, Medline, web of science, Cochrane library, and clinicalitrials.com prior to October 2022. Efficacy data were pooled and analyzed using Review Manager Version 5.3. Pooled analyses of urinary incontinence rates 1, 3, 6, and 12 months postoperatively were conducted, using odds ratio (OR) and 95% confidence intervals (CIs).

RESULTS

We included a total of 15 RCT studies involving 2178 patients received RP. Postoperative UI could be improved after 1 month, 3 months and 6 months, and the OR were 0.26 (95%CI:0.15-0.46) 0.30 (95%CI: 0.11-0.80) 0.20 (95%CI: 0.07- 0.56) in postoperative PFME group compared to no PFME group. However, there was no significant difference between the two groups in 12 months after surgery, and the OR was 0.85(95%CI: 0.48,1.51). There were similar results in perioperative PFME group compared to no PFME group with the OR of 0.35 (95%CI: 0.12, 0.98) and 0.40 (95%CI: 0.21, 0.75) in 1 and 3 months after surgery. Our results indicated no significant difference between perioperative PFME group and postoperative PFME group. The OR was 0.58 (95%CI: 0.20-1.71) 0.58 (95%CI:0.20-0.71) and 0.66 (95%CI: 0.32-1.38) in 1, 3 and 6 months after surgery.

CONCLUSION

Application of PFME after RP significantly reduced the incidence of early postoperative UI, and additional preoperative PFME had no significant improvement on the recovery of UI.

Conservative interventions for managing urinary incontinence after prostate surgery

BACKGROUND

Men may need to undergo prostate surgery to treat prostate cancer or benign prostatic hyperplasia. After these surgeries, men may experience urinary incontinence (UI). Conservative treatments such as pelvic floor muscle training (PFMT), electrical stimulation and lifestyle changes can be undertaken to help manage the symptoms of UI.

OBJECTIVES

To assess the effects of conservative interventions for managing urinary incontinence after prostate surgery.

SEARCH METHODS

We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP and handsearched journals and conference proceedings (searched 22 April 2022). We also searched the reference lists of relevant articles.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs of adult men (aged 18 or over) with UI following prostate surgery for treating prostate cancer or LUTS/BPO. We excluded cross-over and cluster-RCTs. We investigated the following key comparisons: PFMT plus biofeedback versus no treatment; sham treatment or verbal/written instructions; combinations of conservative treatments versus no treatment, sham treatment or verbal/written instructions; and electrical or magnetic stimulation versus no treatment, sham treatment or verbal/written instructions.

DATA COLLECTION AND ANALYSIS

We extracted data using a pre-piloted form and assessed risk of bias using the Cochrane risk of bias tool. We used the GRADE approach to assess the certainty of outcomes and comparisons included in the summary of findings tables. We used an adapted version of GRADE to assess certainty in results where there was no single effect measurement available.

MAIN RESULTS

We identified 25 studies including a total of 3079 participants. Twenty-three studies assessed men who had previously undergone radical prostatectomy or radical retropubic prostatectomy, while only one study assessed men who had undergone transurethral resection of the prostate. One study did not report on previous surgery. Most studies were at high risk of bias for at least one domain. The certainty of evidence assessed using GRADE was mixed. PFMT plus biofeedback versus no treatment, sham treatment or verbal/written instructions Four studies reported on this comparison. PFMT plus biofeedback may result in greater subjective cure of incontinence from 6 to 12 months (1 study; n = 102; low-certainty evidence). However, men undertaking PFMT and biofeedback may be less likely to be objectively cured at from 6 to 12 months (2 studies; n = 269; low-certainty evidence). It is uncertain whether undertaking PFMT and biofeedback has an effect on surface or skin-related adverse events (1 study; n = 205; very low-certainty evidence) or muscle-related adverse events (1 study; n = 205; very low-certainty evidence). Condition-specific quality of life, participant adherence to the intervention and general quality of life were not reported by any study for this comparison. Combinations of conservative treatments versus no treatment, sham treatment or verbal/written instructions Eleven studies assessed this comparison. Combinations of conservative treatments may lead to little difference in the number of men being subjectively cured or improved of incontinence between 6 and 12 months (RR 0.97, 95% CI 0.79 to 1.19; 2 studies; n = 788; low-certainty evidence; in absolute terms: no treatment or sham arm: 307 per 1000 and intervention arm: 297 per 1000). Combinations of conservative treatments probably lead to little difference in condition-specific quality of life (MD -0.28, 95% CI -0.86 to 0.29; 2 studies; n = 788; moderate-certainty evidence) and probably little difference in general quality of life between 6 and 12 months (MD -0.01, 95% CI -0.04 to 0.02; 2 studies; n = 742; moderate-certainty evidence). There is little difference between combinations of conservative treatments and control in terms of objective cure or improvement of incontinence between 6 and 12 months (MD 0.18, 95% CI -0.24 to 0.60; 2 studies; n = 565; high-certainty evidence). However, it is uncertain whether participant adherence to the intervention between 6 and 12 months is increased for those undertaking combinations of conservative treatments (RR 2.08, 95% CI 0.78 to 5.56; 2 studies; n = 763; very low-certainty evidence; in absolute terms: no intervention or sham arm: 172 per 1000 and intervention arm: 358 per 1000). There is probably no difference between combinations and control in terms of the number of men experiencing surface or skin-related adverse events (2 studies; n = 853; moderate-certainty evidence), but it is uncertain whether combinations of treatments lead to more men experiencing muscle-related adverse events (RR 2.92, 95% CI 0.31 to 27.41; 2 studies; n = 136; very low-certainty evidence; in absolute terms: 0 per 1000 for both arms). Electrical or magnetic stimulation versus no treatment, sham treatment or verbal/written instructions We did not identify any studies for this comparison that reported on our key outcomes of interest.

AUTHORS' CONCLUSIONS

Despite a total of 25 trials, the value of conservative interventions for urinary incontinence following prostate surgery alone, or in combination, remains uncertain. Existing trials are typically small with methodological flaws. These issues are compounded by a lack of standardisation of the PFMT technique and marked variations in protocol concerning combinations of conservative treatments. Adverse events following conservative treatment are often poorly documented and incompletely described. Hence, there is a need for large, high-quality, adequately powered, randomised control trials with robust methodology to address this subject.

Effect of different postures of Pilates combined with Kegel training on pelvic floor muscle strength in post-prostatectomy incontinence

PURPOSE

Urinary incontinence seriously affects the daily ability of older males. This study compared the effect of different postures of Pilates combined with Kegel training on pelvic floor muscle strength in post-prostatectomy incontinence.

METHODS

We included 38 valid samples [group A = 13 (less than 3 months after surgery), group B = 15 (4-6 months after surgery), group C = 10 (more than 6 months after surgery)] and surface electromyography (EMG) was used to record the maximum, and root mean square values of participants in the three groups under four postures.

RESULTS

There were significant differences in the maximum and mean values among the three groups. In group A, the mean values were 13.04 ± 1.56, 16.98 ± 1.76, 41.58 ± 4.17, and 24.53 ± 2.45 (P < 0.01), respectively. In group B, the mean values were 13.85 ± 1.55, 18.63 ± 1.44, 45.87 ± 3.31, and 28.63 ± 2.02 (P < 0.01), respectively. In group C, the mean values were 14.80 ± 1.32, 19.59 ± 1.55, 47.85 ± 5.05, and 30.11 ± 2.26 (P < 0.01), respectively. The mean and peak values of surface EMG in the three groups correlated with the four basic movements. R² values were 0.76 and 0.85, 0.77 and 0.88, 0.77 and 0.91, respectively.

CONCLUSIONS

Pilates with Kegel training was superior to Kegel training alone in unit recruitment ability of the pelvic floor muscles. Pilates training in different positions is recommended according to the patient's condition.

Management of Urinary Incontinence Following Radical Prostatectomy: Challenges and Solutions

Urinary incontinence is a common and debilitating problem in patients undergoing radical prostatectomy. Current methods developed to treat urinary incontinence include conservative treatments, such as lifestyle education, pelvic muscle floor training, pharmacotherapy, and surgical treatments, such as bulking agents use, artificial urinary sphincter implants, retrourethral transobturator slings, and adjustable male sling system. Pelvic floor muscle exercise is the most common management to improve the strength of striated muscles of the pelvic floor to try to recover the sphincter weakness. Antimuscarinic drugs, phosphodiesterase inhibitors, duloxetine, and a-adrenergic drugs have been proposed as medical treatments for urinary incontinence after radical prostatectomy. Development of new surgical techniques, new surgical tools and materials, such as male slings, has provided an improvement of outcomes after UI surgery. Such improvement is still ongoing, and the uptake of new devices might lead to even better outcomes after UI surgery.

Efficacy of pelvic floor muscle exercise or therapy with or without duloxetine: a systematic review and network Meta-analysis

OBJECTIVES

Postprostatectomy urinary incontinence (PPUI) is a serious complication despite surgical advances. Treatment options for PPUI include conservative care like Pelvic floor muscle exercise (PFME), which is a physiotherapy performed by the patients themselves; Pelvic floor muscle therapy (PFMT), a physiotherapy performed under the guidance of a therapist, and duloxetine treatment; and surgical interventions. In this study, network meta-analysis (NMA) was performed for direct comparison of these treatment options.

MATERIALS AND METHODS

The NMA pooled the odds ratios and 95% credible intervals using the number of patients achieving urinary continence and the total number of patients in an intention-to-treat population. The treatments were ranked based on the surface under the cumulative ranking curve (SUCRA) probabilities and the rankograms.

RESULTS

The pooled overall ORs of patients achieving urinary continence compared with no treatment was 1.73 (95% CrI: 0.657, 4.71) in PFME, 2.62 (95% CrI: 0.553, 13.5) in PFME plus Duloxetine, and 4.05 (95% CrI: 1.70, 10.2) in PFMT. The SUCRA values of ranking probabilities for each treatment showed high rates of continence in the order of PFMT, PFME plus Duloxetine, and PFME.

CONCLUSION

The results suggest that patients with PPUI should undergo PFMT and consider duloxetine as an additional treatment option.

Comparison of abdominal muscle activity with various verbal instructions and onset activity analysis during draw-in maneuver

Draw-in is a promising intervention for regaining isolated control of the transverse abdominis (TrA). Exercises to stimulate isolated contractions are needed; however, the appropriate methods are unclear. The objectives of this study were to examine how the muscle activity and muscle activity ratio of abdominal muscles change with various verbal instructions and to determine the onset of the abdominal muscles during draw-in. The participants were 21 healthy men. TrA electromyography was performed using fine-wire electrodes, and the internal oblique (IO), external oblique (EO), and rectus abdominis (RA) were determined using surface electrodes. The participants performed seven abdominal exercises according to verbal instructions and isolated voluntary contraction of the TrA for more than 5 sec. The TrA showed higher activity in bracing. IO and EO activities were highest in bracing, whereas RA showed the highest activity in maximum bracing. TrA/IO and TrA/EO were not significantly different between conditions. The results of the onset activity analysis of the abdominal muscles during the draw-in maneuver showed that the TrA was significantly earlier than the other muscles. The activity ratios of TrA to IO and EO were highly individualized and did not differ according to the verbal instruction. Maximum draw-in showed more significant IO activity, and bracing showed co-contraction of the superficial and deep abdominal muscles. During draw-in, the TrA initiated the earliest activity among the abdominal muscles and then isolated activity for 1.1 sec.

Synthetic sling or artificial urinary sphincter for men with urodynamic stress incontinence after prostate surgery: the MASTER non-inferiority RCT

BACKGROUND

Stress urinary incontinence is common in men after prostate surgery and can be difficult to improve. Implantation of an artificial urinary sphincter is the most common surgical procedure for persistent stress urinary incontinence, but it requires specialist surgical skills, and revisions may be necessary. In addition, the sphincter is relatively expensive and its operation requires adequate patient dexterity. New surgical approaches include the male synthetic sling, which is emerging as a possible alternative. However, robust comparable data, derived from randomised controlled trials, on the relative safety and efficacy of the male synthetic sling and the artificial urinary sphincter are lacking.

OBJECTIVE

We aimed to compare the clinical effectiveness and cost-effectiveness of the male synthetic sling with those of the artificial urinary sphincter surgery in men with persistent stress urinary incontinence after prostate surgery.

DESIGN

This was a multicentre, non-inferiority randomised controlled trial, with a parallel non-randomised cohort and embedded qualitative component. Randomised controlled trial allocation was carried out by remote web-based randomisation (1 : 1), minimised on previous prostate surgery (radical prostatectomy or transurethral resection of the prostate), radiotherapy (or not, in relation to prostate surgery) and centre. Surgeons and participants were not blind to the treatment received. Non-randomised cohort allocation was participant and/or surgeon preference.

SETTING

The trial was set in 28 UK urological centres in the NHS.

PARTICIPANTS

Participants were men with urodynamic stress incontinence after prostate surgery for whom surgery was deemed appropriate. Exclusion criteria included previous sling or artificial urinary sphincter surgery, unresolved bladder neck contracture or urethral stricture after prostate surgery, and an inability to give informed consent or complete trial documentation.

INTERVENTIONS

We compared male synthetic sling with artificial urinary sphincter.

MAIN OUTCOME MEASURES

The clinical primary outcome measure was men's reports of continence (assessed from questions 3 and 4 of the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form) at 12 months post randomisation (with a non-inferiority margin of 15%). The primary economic outcome was cost-effectiveness (assessed as the incremental cost per quality-adjusted life-year at 24 months post randomisation).

RESULTS

In total, 380 men were included in the randomised controlled trial (n = 190 in each group), and 99 out of 100 men were included in the non-randomised cohort. In terms of continence, the male sling was non-inferior to the artificial urinary sphincter (intention-to-treat estimated absolute risk difference -0.034, 95% confidence interval -0.117 to 0.048; non-inferiority p = 0.003), indicating a lower success rate in those randomised to receive a sling, but with a confidence interval excluding the non-inferiority margin of -15%. In both groups, treatment resulted in a reduction in incontinence symptoms (as measured by the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form). Between baseline and 12 months' follow-up, the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form score fell from 16.1 to 8.7 in the male sling group and from 16.4 to 7.5 in the artificial urinary sphincter group (mean difference for the time point at 12 months 1.30, 95% confidence interval 0.11 to 2.49; p = 0.032). The number of serious adverse events was small (male sling group, n = 8; artificial urinary sphincter group, n = 15; one man in the artificial urinary sphincter group experienced three serious adverse events). Quality-of-life scores improved and satisfaction was high in both groups. Secondary outcomes that showed statistically significant differences favoured the artificial urinary sphincter over the male sling. Outcomes of the non-randomised cohort were similar. The male sling cost less than the artificial sphincter but was associated with a smaller quality-adjusted life-year gain. The incremental cost-effectiveness ratio for male slings compared with an artificial urinary sphincter suggests that there is a cost saving of £425,870 for each quality-adjusted life-year lost. The probability that slings would be cost-effective at a £30,000 willingness-to-pay threshold for a quality-adjusted life-year was 99%.

LIMITATIONS

Follow-up beyond 24 months is not available. More specific surgical/device-related pain outcomes were not included.

CONCLUSIONS

Continence rates improved from baseline, with the male sling non-inferior to the artificial urinary sphincter. Symptoms and quality of life significantly improved in both groups. Men were generally satisfied with both procedures. Overall, secondary and post hoc analyses favoured the artificial urinary sphincter over the male sling.

FUTURE WORK

Participant reports of any further surgery, satisfaction and quality of life at 5-year follow-up will inform longer-term outcomes. Administration of an additional pain questionnaire would provide further information on pain levels after both surgeries.

European Association of Urology Guidelines on Male Urinary Incontinence

CONTEXT

Urinary incontinence (UI) is a common condition in elderly men causing a severe worsening of quality of life, and a significant cost for both patients and health systems.

OBJECTIVE

To report a practical, evidence-based, guideline on definitions, pathophysiology, diagnostic workup, and treatment options for men with different forms of UI.

EVIDENCE ACQUISITION

A comprehensive literature search, limited to studies representing high levels of evidence and published in the English language, was performed. Databases searched included Medline, EMBASE, and the Cochrane Libraries. A level of evidence and a grade of recommendation were assigned.

EVIDENCE SYNTHESIS

UI can be classified into stress urinary incontinence (SUI), urge urinary incontinence (UUI), and mixed urinary incontinence. A detailed description of the pathophysiology and diagnostic workup has been reported. Simple clinical interventions, behavioural and physical modifications, and pharmacological treatments comprise the initial management for all kinds of UI. Surgery for SUI includes bulking agents, male sling, and compression devices. Surgery for UUI includes bladder wall injection of botulinum toxin A, sacral nerve stimulation, and cystoplasty/urinary diversion.

CONCLUSIONS

This 2022 European Association of Urology guideline summary provides updated information on definition, pathophysiology, diagnosis, and treatment of male UI.

PATIENT SUMMARY

Male urinary incontinence comprises a broad subject area, much of which has been covered for the first time in the literature in a single manuscript. The European Association of Urology Non-neurogenic Male Lower Urinary Tract Symptoms Guideline Panel has released this new guidance, with the aim to provide updated information for urologists to be able to follow diagnostic and therapeutic indications for optimising patient care.

The Effectiveness of Pelvic Floor Muscle Training in Men after Radical Prostatectomy Measured with the Insert Test

A commonly used physiotherapeutic method for the treatment of urinary incontinence (UI) after radical prostatectomy (RP) is pelvic floor muscle training (PFMT). The aim of this study was to evaluate the effectiveness of PFMT by enhanced biofeedback using the 1h pad-weighing test. The following factors were taken into consideration in the analysis of PFMT effectiveness: the relevance of the patients’ age, time from RP, BMI, mental health, functional state, and depression. A total of 60 post-RP patients who underwent 10-week PFMT were studied. They were divided into groups: A (n = 20) and B (n = 20) (random division, time from RP: 2−6 weeks) and group C (time from RP > 6 weeks). Group B had enhanced training using EMG biofeedback. UI improved in all groups: A, p = 0.0000; B, p = 0.0000; and C, p = 0.0001. After the completion of PFMT, complete control over miction was achieved by 60% of the patients in group A, 85% in group B, and 45% in group C. There was no correlation between the results of PFMT efficacy and patients’ age, BMI, time from RP, mental health, functional state, and depression. PFMT is highly effective in UI treatment. The enhancement of PFMT by EMG biofeedback seems to increase the effectiveness of the therapy.

A systematic review of treatment options for post-prostatectomy incontinence

PURPOSE

Urinary incontinence remains common in men after prostatectomy. Current guidance suggests early corrective surgery to those that are still incontinent after trying Pelvic Floor Muscle Therapy, however, other treatments are now available. This review aims to evaluate all currently available treatment options for men with post-prostatectomy incontinence (PPI).

METHODS

A search of MEDLINE and CENTRAL databases on 2/2/2021 produced 879 articles. Any study evaluating incontinence before and after a treatment protocol was eligible for inclusion. After screening, 17 randomized control trials were included, and pre-defined data points were collected. Due to heterogeneity, pooled analysis was not possible, and a descriptive synthesis was produced in accordance with PRISMA guidelines. Cochrane Risk of Bias (RoB) tool was used to evaluate all studies. The search protocol and methods for this study was registered on the PROSPERO database before the search began, ID:(CRD42021229749).

RESULTS

3/17(18%) of studies focussed on pharmacotherapy, 2/17(12%) on vibration therapies, 8/17(47%) on pelvic floor muscle therapy (PFMT), 3/17(18%) on electrical stimulation (ES), and 1/17 (6%) on extracorporeal magnetic innervation (ExMI) as their main intervention. The use of Duloxetine, Solifenacin, PFMT, ES, and ExMI all show effective reduction in incontinence in men suffering from PPI. No study in this review evaluated surgical managements for PPI.

CONCLUSION

A large number of treatments are available for PPI using an array of different methods. For this reason, a variety of treatments could be considered before early invasive procedures, to prevent unnecessary surgery and its associated negative complications.

How to Predict Outcomes from a Biofeedback and Pelvic Floor Muscle Electric Stimulation Program in Patients with Urinary Incontinence after Radical Prostatectomy

OBJECTIVES

The objective of this study was to analyze the pre-operative and intra-operative variables that can condition urinary incontinence (UI) after radical prostatectomy (RP), as well as continence rate recovery during a pelvic floor rehabilitation program.

MATERIALS AND METHODS

A total of 72 cases with UI after RP were prospectively examined. All cases were homogeneously treated by the same surgeon, using the same RP technique. A combination of biofeedback (BF) and pelvic floor electric stimulation (PFES) performed by the same clinician and using the same protocol was used. Clinical, pathologic and surgical variables were analyzed in terms of 24 h pad test results (pad weight and pad-free status).

RESULTS

Prostate volume (PV) strongly varied from 24 to 127 cc (mean ± SD 46.39 ± 18.65 cc), and the baseline pad weight varied from 10 to 1500 cc (mean ± SD 354.29 ± 404.15 cc). PV strongly and positively correlated with the baseline pad weight (r = 0.4215; p = 0.0269) and inversely with the three-month pad weight (r = - 0.4763; p = 0.0213) and pad-free status (r =- 0.3010; p = 0.0429). The risk of a residual pad weight >10 g after the rehabilitative program significantly increased according to PV (p = 0.001) and the baseline pad weight (p = 0.002 and < 0.0001). In particular, PV > 40 cc and a baseline pad weight >400 g significantly (p = 0.010 and p < 0.0001, respectively) and independently predicted a 5.7 and a 35.4 times increase in the risk of a residual pad weight at the three-month follow-up, respectively.

CONCLUSION

This is the first prospective trial whose primary objective is to verify the possible predictors, such as PV, that are able to condition the response to a pelvic floor rehabilitation program for UI after RP.

Effects of Exercise on Sexual Dysfunction in Patients With Prostate Cancer - A Systematic Review

BACKGROUND

Emerging evidence suggests that exercise interventions may improve sexual dysfunction, one of the most common and distressing long-term adverse effects of cancer treatment.

AIM

The aim of this systematic review is to provide an overview of the effects of exercise on sexual dysfunction in prostate cancer patients.

METHODS

A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The systematic literature search was performed on 13th July 2021 using CINAHL, Cochrane Central Register of Controlled Trials, Embase, Medline and Web of Science. Studies were included if they were randomized controlled trials (RCTs) assessing sexual function in prostate cancer patients conducting an exercise intervention alone or in combination with other supportive interventions. The methodological quality was assessed using the Physiotherapy Education Database Score and Jadad scale. Outcomes were reported as between-group differences. Intragroup differences were also reported if significant.

OUTCOMES

Positive intervention effects on sexual function were primarily observed in patients following prostatectomy and undergoing anti-hormone treatment and for pelvic floor muscle exercises as well as aerobic and resistance exercise.

RESULTS

22 RCTs (n = 1.752 patients) met the eligibility criteria, conducting either an exercise-only intervention (n = 10), a multimodal (exercise plus other supportive therapy) intervention (n = 4), or pelvic floor muscle exercises (n = 8). 6 RCTs assessed sexual dysfunction as a primary endpoint and 8 RCTs used dedicated assessment methods. 9 of the 22 RCTs found significant between-group differences in favor of the intervention group.

CLINICAL IMPLICATIONS

The multifaceted etiology of sexual dysfunction provides a strong rationale to further investigate the effects of exercise on sexual dysfunction in prostate cancer patients and also to consider a multidisciplinary approach.

STRENGTHS AND LIMITATIONS

A strength is the comprehensive literature search to identify RCTs involving different exercise interventions and a wide range of sexual function assessments. Further, this is the first systematic review on this topic. The main limitations include the difficulty to compare studies due to the heterogeneity of exercise interventions and low questionnaire completion rates in some studies.

CONCLUSION

Preliminary data from a small number of studies suggest that certain exercise interventions may improve sexual dysfunction in prostate cancer patients, however further trials involving sexual dyfunction as a primary outcome and more comprehensive assessment tools are needed to confirm the rehabilitative and preventive effects of exercise on sexual dysfunction in prostate cancer patients.

A biofeedback-guided programme or pelvic floor muscle electric stimulation can improve early recovery of urinary continence after radical prostatectomy: A meta-analysis and systematic review

PURPOSE

Urinary incontinence (UI) after radical prostatectomy (RP) is an early side effect after catheter removal. This systematic review and meta-analysis were conducted to compare different forms of non-invasive treatments for post-RP UI and to analyse whether the addition of biofeedback (BF) and/or pelvic floor muscle electric stimulation (PFES) to PF muscle exercise (PFME) alone can improve results in terms of continence recovery rate.

MATERIALS AND METHODS

A literature search was performed following the PRISMA guidelines. We performed a cumulative meta-analysis to explore the trend in the effect sizes across subgroups during a 12-months follow-up.

RESULTS

Twenty-six articles were selected. At baseline after RP and catheter removal, mean pad weight varied extremely. At 1- and 3-months intervals, mean difference in pad weight recovery from baseline was significantly higher using guided programs (BF, PFES or both) than using PFME alone (3-months: PFME 111.09 g (95%CI 77.59-144.59), BF 213.81 g (95%CI -80.51-508-13), PFES 306.88 g (95%CI 158.11-455.66), BF + PFES 266.31 g (95%CI 22.69-302.93); P < .01), while at 6- and 12-months differences were similar (P > .04). At 1- and 3-months intervals, event rate (ER) of continence recovery was significantly higher using guided programs than using PFME alone (3-months: PFME 0.40 (95%CI 0.30-0.49), BF 0.49 (95%CI 0.31-0.67), PFES 0.57 (95%CI 0.46-0.69), BF + PFES 0.75 (95%CI 0.60-0.91); P < .01), while at 6- and 12-months ERs were similar.

CONCLUSIONS

Regarding non-invasive treatment of UI secondary to RP, the addition of guided programs using BF or/and PFES demonstrated to improve continence recovery rate, particularly in the first 3-month interval, when compared with the use of PFME alone.

Empowerment-Based Education in Urological Patients: A Scoping Review

Prostate, kidney, and bladder cancer are the three most frequently diagnosed urological cancers. Educational programs could teach patients to become experts in disease management. The aim of this scoping review was to explore the literature to identify the educational requirements and strategies for improving and implementing educational processes for urological patients undergoing surgery. We searched several databases, including PubMed, CINAHL, Embase, Scopus, PsycINFO, and Cochrane Library. All adult patients undergoing urological educational interventions were included in the review. Of 3,197 initially identified articles, 42 were retained. Urological patients undergoing prostatectomy, cystectomy, and nephrectomy require cognitive, psychological, and functional support. For each level of support, several methods exist to provide support, including informational brochures, preoperative counseling, telephone support, online content, educational videos, support groups, individual stress management interventions, peer support, online interventions, partner support, and various educational programs that help the patient manage negative effects associated with the urological intervention.

Focusing on sexual rehabilitation besides penile rehabilitation following radical prostatectomy is important

Erectile dysfunction is commonly reported after radical prostatectomy. Besides the loss of erections, sexual life after prostatectomy is impacted by urinary incontinence, orgasmic dysfunction, and psychological stress. In this review, we describe classical medical therapies used for erectile function rehabilitation such as PDE5 inhibitors and injection therapy. A vast amount of data support the idea of focusing on restoration of sexual function on top of erectile function after prostatectomy. The important strategies described to rehabilitate sexual function include pelvic floor muscle therapy, couple therapy, appropriate preoperative counseling, and focusing on non-penetrative alternatives. A multidisciplinary approach and including the partner is important. Erectile function alone is not sufficient for satisfactory sexual experience and may not be used as a proxy for sexual quality of life. Adding full-spectrum sexual rehabilitation to a standard penile rehabilitation regimen has the highest chances of obtaining satisfactory sexual outcomes in men and their partners after radical prostatectomy.

Climacturia: a comprehensive review assessing pathophysiology, prevalence, impact, and treatment options regarding the "leak of pleasure"

Aim of this review is to summarize and evaluate the current literature on the pathophysiology, prevalence, sociosexual impact, and potential treatment options of climacturia. Climacturia, defined as orgasm-associated urinary incontinence and characterized by great prevalence variability, ranging between 15.7 and 93% was, so far, a relatively neglected post-radical prostatectomy functional side-effect. Recent studies have shown that it can significantly impact the quality of life of couples after prostate cancer treatment. A knowledge gap characterizes the pathophysiologic pathways while treatment is based on empirically chosen treatment options (condom use, presexual intercourse urination) or on therapeutic modalities proposed by low-quality studies (pelvic floor muscle training, penile applied devices). Evidence regarding efficacy of surgical techniques (artificial urinary sphincter, male sling, or dual implantation of penile prosthesis with a sling) for climacturia treatment are limited but with an increasing trend of relevant published data in the last 5 years. The mini-jupette sling plus inflatable penile prosthesis placement is a promising surgical technique that has been studied in a multi-institutional cohort with encouraging results regarding climacturia, erectile dysfunction, and mild-incontinence control. However, future studies with longer follow-up and larger sample sizes are certainly needed to confirm the long-term safety and benefits of this intervention.

Comprehensive reporting of pelvic floor muscle training for urinary incontinence: CERT-PFMT

AIM

To produce a pelvic floor muscle training variation of the Consensus on Exercise Reporting Template (CERT-PFMT).

METHODS

Qualitative methods were used to explore the perspectives of physiotherapists who have postgraduate continence and pelvic floor rehabilitation qualifications on using research evidence to implement pelvic floor muscle training for urinary incontinence. The same experienced facilitator guided the discussions with questions derived from systematic reviews and content experts. The face-to-face focus groups were audio-recorded and verbatim transcripts were thematically analysed. For each CERT item the authors collated participant quotations that identified required explanation or elaboration for the CERT-PFMT. Systematic reviews of pelvic floor muscle training for urinary incontinence were searched by the research team for examples of good reporting.

RESULTS

Twenty- nine continence physiotherapists participated in one of seven focus groups. Participants agreed that all key elements they needed for replicating pelvic floor muscle training interventions from a research report were provided in the published CERT checklist. CERT items 2 (qualifications), 6 (motivation), 7 (progression rules), 8 (exercise description), 13 (intervention description) and 15 (starting level) required additional explanations for pelvic floor muscle training. Clinicians reported that original CERT explanations for items 1, 3-5, 8-12, 14 and 16 could be used without modification.

CONCLUSIONS

The CERT-PFMT reporting guideline has been designed with clinician input to inform how to document pelvic floor muscle training to enable replication in clinical practice. It can be used for research protocols, to construct manuscripts reporting pelvic floor muscle training for urinary incontinence and by journal editors and reviewers.

Preoperative exercise interventions to optimize continence outcomes following radical prostatectomy

Urinary incontinence is a common and predictable consequence among men with localized prostate cancer who have undergone radical prostatectomy. Despite advances in the surgical technique, urinary continence recovery time remains variable. A range of surgical and patient-related risk factors contributing to urinary incontinence after radical prostatectomy have been described, including age, BMI, membranous urethral length and urethral sphincter insufficiency. Physical activity interventions incorporating aerobic exercise, resistance training and pelvic floor muscle training programmes can positively influence the return to continence in men after radical prostatectomy. Traditional approaches to improving urinary continence after radical prostatectomy have typically focused on interventions delivered during the postoperative period (rehabilitation). However, the limited efficacy of these postoperative approaches has led to a shift from the traditional reactive model of care to more comprehensive interventions incorporating exercise-based programmes that begin in the preoperative period (prehabilitation) and continue after surgery. Comprehensive prehabilitation interventions include appropriately prescribed aerobic exercise, resistance training and specific pelvic floor muscle instruction and exercise training programmes. Transperineal ultrasonography is a non-invasive and validated method for the visualization of the action of the pelvic floor musculature, providing real-time visual biofeedback to the patient during specific pelvic floor muscle instruction and training. Importantly, the waiting time before surgery can be used for the delivery of comprehensive prehabilitation exercise-based interventions to increase patient preparedness in the lead-up to surgery and optimize continence and health-related quality-of-life outcomes following radical prostatectomy.

Generating comprehensive comparative evidence on various interventions for penile rehabilitation in patients with erectile dysfunction after radical prostatectomy: a systematic review and network meta-analysis

Background

We aim to present a comprehensive comparison of various treatments in the management of penile recovery after radical prostatectomy (RP) and provide recommendations for future research.

Methods

Literature search of electronic databases including PubMed, the Cochrane Library, Embase, PsycInfo, and Web of Science, and manual retrieval were conducted from inception through March 2020. “Erectile dysfunction” and “prostatectomy” were used as the Mesh terms. The patients, intervention, comparison, outcome, and study design (PICOS) approach were used to define study eligibility. Two authors independently selected studies, evaluated the methodological quality, and extracted data using Cochrane Collaboration’s tools. The data analysis was completed by STATA version 14.2.

Results

A total of 24 studies with 3,500 patients were incorporated in the final analysis after screening 6,131 records. Our findings indicated that vacuum constriction devices (VCD) ranked 1st which meant that patients in VCD group had the best effect regarding mean IIEF scores within 3 months after RP, and no significant difference was observed between VCD and VCD with 20 mg/day tadalafil (V20DT) (MD: 5.44; 95% CI: −0.81 to 11.69). VCD and 50 mg/day sildenafil (VC50DS) showed superiority over 50 mg/day sildenafil (50DS) (MD: 3.75; 95% CI: 2.74–4.76) and intraurethral alprostadil 125–250 µg (MD: 3.05; 95% CI: 0.38 to 5.72), respectively. Moreover, V20DT showed significant superiority over the other interventions for ≥6 months mean International Index Erectile of Function (IIEF) scores after RP. Monotherapy appeared to have similar efficacy in terms of mean IIEF scores and proportion of patients return to baseline, and the effect of phosphodiesterase type 5 inhibitors (PDE5is) did not seem to be affected by the patterns of administration (regular or on demand).

Conclusions

The combination therapy showed certain advantages over monotherapy, and we recommended the combination of VCD and PDE5is to be considered in the clinical management of penile rehabilitation after RP.

Regenerated Cell Therapy for Stress Urinary Incontinence: A Meta-Analysis

PURPOSE

To evaluate the efficacy and safety of regenerated cell therapy for stress urinary incontinence (UI) in humans.

METHODS

We searched articles from PubMed, Embase, and the Cochrane Library database published before February 24, 2020. Of 396 records identified, 23 articles on human clinical research met our criteria, including a total of 890 patients. Stata/SE12.0 software was used to analyze cure, efficiency (cure rate plus improvement rate), and complication rates.

RESULTS

No significant differences in cure rates and effective rates were observed for any cell type in males. However, in females, the myocytes with fibroblasts subgroup (82%) and nucleated cells with platelets subgroup (89%) exhibited significantly higher cure rates compared with the other two subgroups (25% and 36%). Pooled effective rates of myocytes and fibroblasts (92%) and nucleated cells with platelets (97%) were also higher compared with the other two subgroups (72% and 60%). Pooled complication rates were 23% and 26% in males and females, respectively, and there were some differences among subgroups. Although some studies reported postoperative complications, no serious complications were reported and most recovered within 1-2 weeks.

CONCLUSIONS

Limited studies have indicated the safety and effectiveness of regenerated cells for treating stress UI in the follow-up period, which may be an ideal method to treat stress UI in the future. Moreover, nucleated cells with platelets and myocytes with fibroblasts were markedly effective, but whether cell injection therapies elicit superior effects need further confirmation.

Current management strategy of treating patients with erectile dysfunction after radical prostatectomy: a systematic review and meta-analysis

The aim of this study is to present a summary of current evidence concerning the various treatments in the management of penile rehabilitation after radical prostatectomy (RP) and provide recommendations for future research. Randomized controlled trials (RCTs) were identified from electronic databases including PubMed, the Cochrane Library, Embase, and Web of Science from inception through March 2020 with no limitation to language. Comparable data from each study were combined in a meta-analysis where possible, otherwise data were synthesized narratively. The data analysis was completed by Review Manager version 5.3. A total of 39 RCTs were included in this study. At present, phosphodiesterase type 5 inhibitors (PDE5is) remain the first-line treatment for patients with erectile dysfunction (ED) after RP. Compared with the placebo group, patients in regular PDE5is group (mean difference (MD): 0.76; 95% confidence interval (CI): 1.69-4.44; p < 0.0001) and on demand group (MD: 3.92; 95% CI: 2.95-4.88; p < 0.00001) had a significantly higher mean Erectile Function domain of the International Index of Erectile Function (IIEF-EF) scores within 3 months after RP. As for the proportion of IIEF-EF ≥ 22, patients in regular PDE5is group and on demand PDE5is group had significantly higher proportion than those in placebo group 6 months after RP, and the odds ratios were 1.87 (95% CI: 1.32-2.66; p = 0.0005) and 2.17 (95% CI: 1.20-3.93; p = 0.01), respectively. No significant difference was observed between regular PDE5is group and on demand group regardless of mean IIEF-EF score or the proportion of IIEF-EF ≥ 22. Intracorporeal injection therapy seemed to have similar efficacy to PDE5is. The International Index of Erectile Function-5 items (IIEF-5) scores were significantly higher in vacuum constriction devices group than control group at 6-9 months after RP (MD: 6.70, 95% CI: 2.30-11.10, p = 0.003) with great between-study heterogeneity (p = 0.06, I² = 72%). The other therapeutics including low-intensity extracorporeal shockwave therapy, statin therapy, psychotherapy interventions, and pelvic floor muscle training plus electrical stimulation showed certain improvement on erectile function. We found that the combination therapy showed certain advantages over monotherapy. Currently, PDE5is-based combination therapy remains the mainstream treatment for ED after RP. Intracorporeal injection therapy and vacuum therapy could be served as alternative treatments if PDE5is are ineffective and contraindicated.

The therapeutic effect of pelvic floor muscle exercise on urinary incontinence after radical prostatectomy: a meta-analysis

Pelvic floor muscle exercise (PFME) is the most common conservative management for urinary incontinence (UI) after radical prostatectomy (RP). However, whether the PFME guided by a therapist (G-PFME) can contribute to the recovery of urinary continence for patients after RP is still controversial. We performed this meta-analysis to investigate the effectiveness of G-PFME on UI after RP and to explore whether the additional preoperative G-PFME is superior to postoperative G-PFME alone. Literature search was conducted on Cochrane Library, Embase, Web of Science, and PubMed, to obtain all relevant randomized controlled trials published before March 1, 2018. Outcome data were pooled and analyzed with Review Manager 5.3 to compare the continence rates of G-PFME with control and to compare additional preoperative G-PFME with postoperative G-PFME. Twenty-two articles with 2647 patients were included. The continence rates of G-PFME were all superior to control at different follow-up time points, with the odds ratio (OR) (95% confidence interval [CI]) of 2.79 (1.53–5.07), 2.80 (1.87–4.19), 2.93 (1.19–7.22), 4.11 (2.24–7.55), and 2.41 (1.33–4.36) at 1 month, 3 months, 4 months, 6 months, and 12 months after surgery, respectively. However, there was no difference between additional preoperative G-PFME and postoperative G-PFME, with the OR (95% CI) of 1.70 (0.56–5.11) and 1.35 (0.41–4.40) at 1 month and 3 months after RP, respectively. G-PFME could improve the recovery of urinary continence at both early and long-term stages. Starting the PFME preoperatively might not produce extra benefits for patients at early stage, compared with postoperative PFME.

Do features of randomized controlled trials of pelvic floor muscle training for postprostatectomy urinary incontinence differentiate successful from unsuccessful patient outcomes? A systematic review with a series of meta-analyses

AIMS

Efficacy of pelvic floor muscle training (PFMT) for postprostatectomy incontinence (PPI) differs between randomized clinical trials (RCT). This might be explained by variation in content/delivery of PFMT (eg, biofeedback, muscles targeted, and time of commencement of training). This review investigated whether outcome of meta-analysis differs based on presence or not of specific RCT features.

METHODS

PubMed, CINAHL, EMBASE, Physiotherapy Evidence Database (PEDro), and Cochrane were searched for RCTs that investigated efficacy of PFMT on PPI. PFMT details and outcomes were extracted. Methodological quality and comprehensiveness of PFMT reporting was assessed using the PEDro scale and Consensus on Reporting Template, respectively. Effect size and 95% confidence intervals were calculated for incontinence rate at 3 months. To identify features that influenced efficacy, separate meta-analyses were performed for studies with and without specific features.

RESULTS

Twenty-two trials were included, and 15 were used for meta-analysis of 3-month outcomes. Overall, meta-analysis showed reduced incontinence with PFMT (risk ratio [RR] = 0.85; I² = 55%; P = .005). Meta-analyses showed better outcomes for PFMT than control groups when the study included preoperative PFMT (RR = 0.76; I² = 30%; P = .006), biofeedback (RR = 0.73; I² = 58%; P = .006), instruction to contract around the urethra (RR = 0.9; I² = 43%; P = .009), a control group without PFMT instruction (RR = 0.85; I² = 69%; P = .05), inclusion of all men irrespective of continence status (RR = 0.84; I² = 30%; P = .003) and continence defined as no leakage (RR = 0.85; I² = 48%; P = .05).

CONCLUSIONS

Preoperative PFMT, biofeedback, urethral instructions, no PFMT instruction for controls, inclusion of all men, and continence defined as no leakage are features associated with successful patient outcomes. Future studies should consider these features in design of interventions and pooling data for meta-analysis.

Preoperative pelvic floor muscle exercise for early continence after holmium laser enucleation of the prostate: a randomized controlled study

Background

Transient postoperative urinary incontinence is a bothersome complication of holmium laser enucleation of the prostate (HoLEP). The effects of preoperative pelvic floor muscle exercise (PFME) for early recovery of continence after HoLEP have never been elucidated. The aim of this study was to determine the benefit of preoperatively started PFME for early recovery of continence after HoLEP.

Methods

We randomly assigned patients to start PFME preoperatively and continue postoperatively (group A) or start PFME no earlier than the postoperative period (group B). The primary outcome was time to complete urinary control, defined as no pad usage. The secondary outcome was measured using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) score. Univariate and multivariate analyses were performed to identify parameters associated with recovery of continence after HoLEP.

Results

Seventy patients were randomized across groups A (n = 35) and B (n = 35). Patients’ characteristics were not different between groups A and B. The postoperative urinary incontinence rate significantly decreased in group A compared with that in group B at 3 months postoperatively [3% vs. 26% (P = 0.01)]. However, there were no significant differences between groups A and B at 3 days [40% vs. 54% (P = 0.34)], 1 month [37% vs. 51% (P = 0.34)], and 6 months [0% vs. 3% (P = 1.00)] postoperatively, respectively. The postoperative ICIQ-SF score was not significantly different between groups A and B at any time point postoperatively. In univariate analysis, patients who performed preoperative PFME had a 0.56-fold lower risk of urinary incontinence 1 month after HoLEP and a 0.08-fold lower risk of urinary incontinence 3 months after HoLEP.

Conclusions

Preoperatively started PFME appears to facilitate improvement of early urinary continence after HoLEP.

Reconsideration of pelvic floor muscle training to prevent and treat incontinence after radical prostatectomy

Urinary incontinence is common after radical prostatectomy. Pelvic floor muscle training provides a plausible solution. Although early trials provided promising results, systematic reviews have questioned the efficacy of this intervention. A major consideration is that most clinical trials in men have applied principles developed for pelvic floor muscle training for stress urinary incontinence in women, despite differences in anatomy between sexes and differences in the mechanisms for continence/incontinence. Literature regarding continence control in men has been conflicting and often based on erroneous anatomy. New understanding of continence mechanisms in men, including the complex contribution of multiple layers of striated pelvic floor muscles, and detailed consideration of the impact of radical prostatectomy on continence anatomy and physiology, have provided foundations for a new approach to pelvic floor muscle training to prevent and treat incontinence after prostatectomy. An approach to training can be designed to target the pathophysiology of incontinence. This approach relies on principles of motor learning and exercise physiology, in a manner that is tailored to the individual patient. The aims of this review are to consider new understanding of continence control in men, the mechanisms for incontinence after radical prostatectomy, and to review the characteristics of a pelvic floor muscle training program designed to specifically target recovery of continence after prostatectomy.

New concept for treating urinary incontinence after radical prostatectomy with radiofrequency: phase 1 clinical trial

To describe the clinical response and side effects of radiofrequency treatment in patients with urinary incontinence after radical prostatectomy. This is a phase 1 clinical trial with 10 men up to 65 years of age who had urinary incontinence after radical prostatectomy, post void residual volume < 50 ml verified by ultrasonography, pad test ≥ 1 g, and PSA < 0.2 ng/ml. pad test and self-administered questionnaires were used to assess clinical response. Scales were used to measure treatment satisfaction and improvement in symptoms. Participants underwent five sessions of 2 min of non-ablative endoanal radiofrequency (41 °C). The evaluated co-primary endpoints were urinary incontinence volume and urinary symptoms, analyzed by the Wilcoxon nonparametric test; residual volume, and self-reports to assess safety. The participants' mean age was 57.5 ± 4.9. The initial pad test score was 6.5 g (1.7-50.0) with a final score of 2.0 g (0.0-9.0) (p < 0.01). Ultrasonography showed no alteration of residual volume. A decrease of urinary loss was found in nine patients, three of them showed a complete resolution of urinary loss. A decrease in irritative micturition symptoms was found as well, but no improvement in the quality of life was shown. Regarding treatment satisfaction, two patients were neutral, six satisfied, and two very satisfied. Limitations included pain while the endoanal electrode was inserted. Four patients indicated pain during treatment, but overall results were positive. The reduction of urinary loss and irritative micturition symptoms increased patients' satisfaction scores, without improving their perception of quality of life.

Practical help for specifying the target difference in sample size calculations for RCTs: the DELTA2 five-stage study, including a workshop

BACKGROUND

The randomised controlled trial is widely considered to be the gold standard study for comparing the effectiveness of health interventions. Central to its design is a calculation of the number of participants needed (the sample size) for the trial. The sample size is typically calculated by specifying the magnitude of the difference in the primary outcome between the intervention effects for the population of interest. This difference is called the 'target difference' and should be appropriate for the principal estimand of interest and determined by the primary aim of the study. The target difference between treatments should be considered realistic and/or important by one or more key stakeholder groups.

OBJECTIVE

The objective of the report is to provide practical help on the choice of target difference used in the sample size calculation for a randomised controlled trial for researchers and funder representatives.

METHODS

The Difference ELicitation in TriAls2 (DELTA2) recommendations and advice were developed through a five-stage process, which included two literature reviews of existing funder guidance and recent methodological literature; a Delphi process to engage with a wider group of stakeholders; a 2-day workshop; and finalising the core document.

RESULTS

Advice is provided for definitive trials (Phase III/IV studies). Methods for choosing the target difference are reviewed. To aid those new to the topic, and to encourage better practice, 10 recommendations are made regarding choosing the target difference and undertaking a sample size calculation. Recommended reporting items for trial proposal, protocols and results papers under the conventional approach are also provided. Case studies reflecting different trial designs and covering different conditions are provided. Alternative trial designs and methods for choosing the sample size are also briefly considered.

CONCLUSIONS

Choosing an appropriate sample size is crucial if a study is to inform clinical practice. The number of patients recruited into the trial needs to be sufficient to answer the objectives; however, the number should not be higher than necessary to avoid unnecessary burden on patients and wasting precious resources. The choice of the target difference is a key part of this process under the conventional approach to sample size calculations. This document provides advice and recommendations to improve practice and reporting regarding this aspect of trial design. Future work could extend the work to address other less common approaches to the sample size calculations, particularly in terms of appropriate reporting items.

Efficacy of a personalised pelvic floor muscle training programme on urinary incontinence after radical prostatectomy (MaTchUP): protocol for a randomised controlled trial

INTRODUCTION

Prostate cancer is the most common cancer in men. Prostatectomy is the most common treatment. Morbidity from prostatectomy is high-80% of men experience urinary incontinence which negatively impacts the quality of life. Postsurgical pelvic floor muscle training is commonly prescribed but recent systematic reviews found no evidence of efficacy. We propose a new treatment that commences preoperatively and targets functional training of specific pelvic floor muscles that contribute to urinary continence. Assessment and biofeedback using transperineal ultrasound imaging assists in training. This will be compared against conventional training (maximal pelvic floor muscle contraction assessed by digital rectal examination) and no training. Embedded physiological studies will allow the investigation of moderation and mediation of the treatment effect on the outcomes.

METHODS AND ANALYSIS

This randomised clinical trial will include 363 men scheduled to undergo radical prostatectomy for prostate cancer. Participants will be randomised into urethral training, conventional training and no training groups. Clinical data will be collected at baseline (1-2 weeks presurgery) and postsurgery after catheter removal, weekly to 3 months (primary endpoint) and monthly to 12 months. Outcomes include 24-hour pad weight test (primary), incontinence, quality of life and cost-effectiveness data. Neuromuscular control measures of pelvic floor muscles will be measured at baseline, postsurgery, 6 weeks, 3 and 12 months. Study assessors and statisticians will be blinded to the group allocation.

ETHICS AND DISSEMINATION

This study is registered with the Australian New Zealand Clinical Trials Registry and has ethical approval from the university and host hospital ethics committees. Trial outcomes will be shared via national/international conference presentations and peer-reviewed journal publications.

Effectiveness of physiotherapy interventions for improving erectile function and climacturia in men after prostatectomy: a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

To determine the effectiveness of physiotherapy interventions for postprostatectomy erectile dysfunction and climacturia.

DATA SOURCES

Multiple databases were searched from database inception to February 2019.

REVIEW METHODS

Randomized controlled trials comparing physiotherapy interventions to control were included.

RESULTS

The search yielded 127 potentially relevant articles; seven met the inclusion criteria and were included in the review. Meta-analysis of two studies revealed a statistically significant effect of pelvic floor muscle training (PFMT) plus biofeedback compared to the no treatment control group for erectile function at the12-month follow-up period (risk ratio (RR) = 3.65, 95% confidence interval (CI) = 1.02-13.05; P = 0.05). Data from one small study (n = 31) identified a greater number of men reporting improved climacturia in the PFMT plus electrical stimulation group compared to the no treatment control group, and the overall effect was significant (RR = 15.60, 95% CI = 0.95-254.91; P = 0.05). Meta-analyses of two studies found no statistically significant differences between groups receiving PFMT and no treatment control for erectile function or climacturia at long-term follow-up.

CONCLUSIONS

PFMT augmented with biofeedback improves erectile function after prostatectomy. Data from a single study found PFMT combined with electrical stimulation to be beneficial for postprostatectomy climacturia. However, electrical stimulation is recommended for terminally ill people only. The effect of PFMT alone on postprostatectomy erectile dysfunction and climacturia remains inconclusive. However, this is likely to be affected by the participant adherence and physiotherapy supervision. High-quality trials providing intensive supervision and due consideration of adherence factors are recommended.

Effectiveness of Pelvic Floor Muscle Training Alone and in Combination With Biofeedback, Electrical Stimulation, or Both Compared to Control for Urinary Incontinence in Men Following Prostatectomy: Systematic Review and Meta-Analysis

BACKGROUND

The efficacy of pelvic floor muscle training (PFMT) alone and in combination with biofeedback (BFB), electrical stimulation (ES), or both for urinary incontinence in men following prostatectomy is inconclusive.

PURPOSE

The purpose of this study was to determine whether PFMT works well alone or in combination with BFB, ES, or both in comparison with a control.

DATA SOURCES

The databases Ovid Medline, EMBASE, CENTRAL, Scopus, and Web of Science, and the specialized register of the Citroen Incontinence Review Group were searched from study inception to August 2017. Abstract proceedings from urological meetings, including the European Association of Urology and the American Urological Association, were also searched.

STUDY SELECTION

Randomized controlled trials that compared PFMT alone and PFMT with ES, BFB, or both and no treatment, placebo, or sham were included in the review.

DATA EXTRACTION, SYNTHESIS, AND QUALITY

Two independent reviewers completed data extraction and quality appraisal. The Grading of Recommendations, Assessment, Development, and Evaluation tool was used for quality appraisal. Meta-analysis was done with software used for preparing and maintaining Cochrane reviews.

LIMITATIONS

Methodological flaws in the included studies limited internal validity.

CONCLUSIONS

PFMT alone, PFMT plus BFB and ES, and PFMT plus ES were more effective than the control for urinary incontinence following prostatectomy. The effect of PFMT plus BFB on postprostatectomy incontinence remains uncertain.

Optimal search strategies for identifying moderators and predictors of treatment effects in PubMed

BACKGROUND

Treatment effects differ across patients. To guide selection of treatments for patients, it is essential to acknowledge these differences and identify moderators or predictors. Our aim was to generate optimal search strategies (commonly known as filters) for PubMed to retrieve papers identifying moderators and predictors of treatment effects.

METHODS

Six journals were hand-searched for articles on moderators or predictors. Selected articles were randomly allocated to a development and validation set. Search terms were extracted from the development set and tested for their performance. Search filters were created from combinations of these terms and tested in the validation set.

RESULTS

Of 4407 articles, 198 were considered to be relevant. The most sensitive filter in the development set '("Epidemiologic Methods" [MeSH] OR assign* OR control*[tiab] OR trial*[tiab]) AND therapy*[sh]' yielded in the validation set a sensitivity of 89% [88%-90%] and a specificity of 80% [79%-82%].

CONCLUSIONS

The search filters created in this study can help to efficiently retrieve evidence on moderators and predictors of treatment effect. Testing of the filters in multiple domains should reveal robustness across disciplines. These filters can facilitate the retrieval of evidence on moderators and predictors of treatment effects, helping the implementation of stratified or personalised health care.

The Role of Preoperative Puborectal Muscle Function Assessed by Transperineal Ultrasound in Urinary Continence Outcomes at 3, 6, and 12 Months After Robotic-Assisted Radical Prostatectomy

PURPOSE

The efficacy of pelvic floor muscle training (PFMT) for men with postprostatectomy incontinence (PPI) after robotic-assisted radical prostatectomy (RARP) is controversial and the mechanism for its possible effect remains unclear. The aim of this study was to investigate the relationship between bladder neck (BN) displacement, as a proxy for puborectal muscle activation, and continence outcomes after RARP.

METHODS

Data were extracted from the South Australian Prostate Cancer Clinical Outcomes Collaborative database for men undergoing RARP by high volume surgeons who attended preoperative pelvic floor physiotherapy for pelvic floor muscle (PFM) training between 2012 and 2015. Instructions were to contract the PFM as if stopping the flow of urine. BN displacement was measured with 2-dimensional transperineal ultrasound, without digital rectal examination. Urinary continence status was assessed preoperatively and at 3, 6, and 12 months using the Expanded Prostate Cancer Index Composite 26. Data were analysed using logistic regression and mixed effects linear modelling. Confounding variables considered were baseline continence, age at diagnosis, margin status, nerve sparing procedures and pathological stage.

RESULTS

Of 671 eligible men, 358 met the inclusion criteria and were available for analysis, with 136 complete datasets at 12-month follow-up. While BN movement was associated with preoperative continence, there was no significant effect of BN displacement on the change in urinary continence at 12 months postprostatectomy (P=0.81) or on the influence of time on continence over 3-12 months.

Conclusions

Continence outcomes were not associated with BN displacement, produced by activity of the puborectal portion of the levator ani muscle, at 3, 6, or 12 months after RARP. These results suggest that the puborectal muscle does not play a role in the recovery of continence after RARP and may help to explain the negative findings of many studies of PFMT for PPI.

Design of programs to train pelvic floor muscles in men with urinary dysfunction: Systematic review

AIMS

Pelvic floor muscle training (PFMT) is a first line conservative treatment for men with urinary dysfunction, but reports of its efficacy are variable. This study aimed to systematically review the content of PFMT programs used for urinary dysfunction in men.

METHODS

Electronic databases (PubMed, CINAHL, EMBASE, Cochrane, PEDro) were searched for studies that used PFMT in the treatment of adult men with urinary dysfunction. Details of PFMT treatment sessions and home exercise protocols were extracted. Criteria specific to PFMT were developed, based on the Consensus on Exercise Reporting Template, and applied to all studies to measure the comprehensiveness of the PFMT description in the manuscript.

RESULTS

Results from the 108 included studies indicate substantial heterogeneity in both the content of PFMT and the quality of reporting of the components of the exercise regimes. There was notable disparity in the muscles targeted by the interventions (and few focused on urethral control despite the use in management of urinary conditions) and the intensity of the programs (eg, 18-240 contractions per day). Most studies were missing key details of description of the PFMT programs (eg, the position in which the pelvic floor muscle [PFM] contraction was taught and how it was assessed, methods used to ensure exercise adherence).

CONCLUSIONS

Variation in content of PFMT programs is likely to contribute to variation in the reported efficacy for management of urinary dysfunction in men, and unclear description of the details of the evaluated programs makes it difficult to identify the effective/ineffective components.

Evaluation of urodynamic parameters after sling surgery in men with post-prostatectomy urinary incontinence

Objective:

To evaluate urodynamic alterations after sub-urethral sling surgery (SSU) in patients with post-prostatectomy urinary incontinence (PPUI).

Materials and Methods:

We evaluated data of 22 patients submitted to radical prosta- tectomy (RP) or transurethral resection of prostate (TURP) that presented post-surgical urinary incontinence and were treated with SSU implant in a pilot study previously performed in our institution.

Methods:

Those patients with PPUI were evaluated by urodynamic exam (UD) before and after surgery, and the parameters were compared, including uroflow, cystometry and micturition study. Exclusion criteria included patients without pre-operatory urodynamic study, those with urethral stenosis, those not healed of prostate cancer, pa- tients without clinical conditions to be submitted to urodynamic study and those with severe neurological diseases or that refused to sign the consent form. Results were analyzed statistically by Fisher, Wilcoxon or Mann-Whitney tests.

Results:

During free uroflow, none parameters showed any statistical significant differ- ences. During cystometry, there were also no statistical differences and the same was observed at pressure versus flow study; the exception was at maximal flow detrusor pressure (PdetQmax), that was lower at post-operatory (p=0.028). In relation to the presence of urinary dysfunctions associated to PPUI, we observed a significant reduc- tion of detrusor overactivity (p=0.035) in relation to pre-operatory period.

Conclusion:

SSU surgery significantly reduced detrusor overactivity and PdetQMax; however, there were no alterations of other evaluated urodynamic parameters.

The use of Mechanical Diagnosis and Therapy (MDT) in patients with lower urinary tract symptoms (LUTS): case series

Lower urinary tract symptoms (LUTS) are highly prevalent among men over the age of 40. Even though associations between lumbar spine conditions and LUTS have been documented in the literature, no studies have detailed a specific lumbar assessment and classification process, and the related treatment effects in patients with LUTS. In this case series, we present three male patients with LUTS as primary complaints, who were evaluated and treated with Mechanical Diagnosis and Therapy (MDT) for the lumbar spine. The duration of their symptoms was between 4 months and 7 years. Urogenital pathologies were ruled out for all patients. The Chronic Prostatitis Symptom Index was used as a functional outcome measure. All patients were classified as having lumbar derangements. Treatment of derangements with directional preference exercises resulted in the improvement of their LUTS, with clinically significant improvements (56.0%-77.4%) in functional outcome measures over an average of six sessions. Preliminary indications suggest that these LUTS cases may possibly have had a lumbar spine origin and "mechanical" nature. Therefore, they may be within the scope of MDT assessments and interventions. With careful monitoring of symptoms, MDT may serve as a screening tool and conservative treatment option.

Male synthetic sling versus artificial urinary sphincter trial for men with urodynamic stress incontinence after prostate surgery (MASTER): study protocol for a randomised controlled trial

Background

Stress urinary incontinence (SUI) is a frequent adverse effect for men undergoing prostate surgery. A large proportion (around 8% after radical prostatectomy and 2% after transurethral resection of prostate (TURP)) are left with severe disabling incontinence which adversely effects their quality of life and many are reliant on containment measures such as pads (27% and 6% respectively). Surgery is currently the only option for active management of the problem.

The overwhelming majority of surgeries for persistent bothersome SUI involve artificial urinary sphincter (AUS) insertion. However, this is expensive, and necessitates manipulation of a pump to enable voiding. More recently, an alternative to AUS has been developed – a synthetic sling for men which elevates the urethra, thus treating SUI. This is thought, by some, to be less invasive, more acceptable and less expensive than AUS but clear evidence for this is lacking.

The MASTER trial aims to determine whether the male synthetic sling is non-inferior to implantation of the AUS for men who have SUI after prostate surgery (for cancer or benign disease), judged primarily on clinical effectiveness but also considering relative harms and cost-effectiveness.

Methods/design

Men with urodynamic stress incontinence (USI) after prostate surgery, for whom surgery is judged appropriate, are the target population. We aim to recruit men from secondary care urological centres in the UK NHS who carry out surgery for post-prostatectomy incontinence. Outcomes will be assessed by participant-completed questionnaires and 3-day urinary bladder diaries at baseline, 6, 12 and 24 months. The 24-h urinary pad test will be used at baseline as an objective assessment of urine loss. Clinical data will be completed at the time of surgery to provide details of the operative procedures, complications and resource use in hospital. At 12 months, men will also have a clinical review to evaluate the results of surgery (including another 24-h pad test) and to identify problems or need for further treatment.

Discussion

A robust examination of the comparative effectiveness of the male synthetic sling will provide high-quality evidence to determine whether or not it should be adopted widely in the NHS.

Argus T® versus Advance® Sling for postprostatectomy urinary incontinence: A randomized clinical trial

Objective

To compare the results of two slings, Argus T® and Advance®, for the treatment of postprostatectomy urinary incontinence (PPUI). Material and Methods: From December 2010 to December 2011, 22 patients with PPUI were randomized as follows: 11 (mean age 62.09(±5.30)) underwent treatment with Advance® and 11 (mean age 62.55(±8.54)) with Argus T®. All patients were evaluated preoperatively with urodynamic testing, quality of life questionnaire (ICIQ-SF), voiding diary and 24-hour pad test. Exclusion criteria were: neurological diseases, severe detrusor overactivity and urethral stenosis. Evaluation was performed at 6, 12 and 18 months after the surgery. After implantation of the Argus T® sling, patients who experienced urine leakage equal to or greater than the initial volume underwent adjustment of the sling tension. Results were statistically analyzed using the Fisher’s test, Kolmogorov-Smirnov test, Friedman’s non-parametric test or the Mann-Whitney test.

Results

Significant improvement of the 24-hour pad test was observed with the Argus T® sling (p=0.038) , With regard to the other parameters, there was no significant difference between the two groups. Removal of the Argus T® device due to perineal pain was performed in one patient (9%). Despite non uniform results, both devices were considered useful to improve quality of life (ICIQ-SF): Argus T® (p=0.018) and Advance® (p=0.017).

Conclusions

Better results were observed in the 24h pad test and in levels of satisfaction with the Argus T® device. Both slings contributed to improve quality of life (ICIQ-SF), with acceptable side effects.

Can incontinence be cured? A systematic review of cure rates

BACKGROUND

Incontinence constitutes a major health problem affecting millions of people worldwide. The present study aims to assess cure rates from treating urinary (UI) or fecal incontinence (FI) and the number of people who may remain dependent on containment strategies.

METHODS

Medline, Embase, PsycINFO, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, and PEDro were searched from January 2005 to June 2015. Supplementary searches included conference abstracts and trials registers (2013-2015). Included studies had patients ≥ 18 years with UI or FI, reported treatment cure or success rates, had ≥ 50 patients treated with any intervention recognized in international guideline algorithms, a follow-up ≥ 3 months, and were published from 2005 onwards. Title and abstract screening, full paper screening, data extraction and risk-of-bias assessment were performed independently by two reviewers. Disagreements were resolved through discussion or referral to a third reviewer where necessary. A narrative summary of included studies is presented.

RESULTS

Most evidence was found for UI: Surgical interventions for stress UI showed a median cure rate of 82.3% (interquartile range (IQR), 72-89.5%); people with urgency UI were mostly treated using medications (median cure rate for antimuscarinics = 49%; IQR, 35.6-58%). Pelvic floor muscle training and bulking agents showed lower cure rates for UI. Sacral neuromodulation for FI had a median cure rate of 38.6% (IQR, 35.6-40.6%).

CONCLUSIONS

Many individuals were not cured and hence may continue to rely on containment. No studies were found assessing success of containment strategies. There was a lack of data in the disabled and in those with neurological diseases, in the elderly and those with cognitive impairment. Surgical interventions were effective for stress UI. Other interventions for UI and FI showed lower cure rates. Many individuals are likely to be reliant on containment strategies.

Recovery of urinary continence after radical prostatectomy

INTRODUCTION

In the era of minimally-invasive surgery, urinary incontinence (UI) after radical prostatectomy (RP) still represents a troublesome issue for a considerable rate of patients. Factors associated with the risk of post-RP UI, need to be carefully assessed throughout the overall clinical management process thus including the pre-operative, intra-operative and post-operative setting.

AREAS COVERED

This review analyses current published evidences regarding clinical and surgical aspects associated with urinary continence (UC) recovery after RP. A careful evaluation of patient's clinical characteristics should be carried out before surgery in order to properly counsel the patients regarding the risk of UI. In the last two decades, the advent of robotic surgery has led to an overall improvement of functional outcomes after RP, thanks to the development of different surgical strategies based on either the 'preservation' or the 'reconstruction' of the anatomical elements responsible for urinary continence. Finally, several therapeutic strategies including either a conservative approach, or pharmacological and surgical treatments, should be carefully considered for the post-operative management of UI. Expert commentary: A comprehensive pre-operative patient's clinical assessment, along with a proper and well-conducted surgical procedure and an effective post-operative care management are essential element to achieve a high probability of UC recovery.
