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

Control4Life: A randomized controlled trial protocol examining the feasibility and efficacy of a combined pelvic health rehabilitation and exercise fitness program for individuals undergoing prostatectomy

BACKGROUND

Urinary incontinence (UI), erectile dysfunction and cardiometabolic conditions are common after prostatectomy for prostate cancer (PCa). Although physical activity could improve overall survival and quality of survivorship, fear of UI can restrict participation in exercise. Individuals with PCa could benefit from therapeutic exercise programming to support continence recovery and cardiometabolic health.

AIM

The main objective of this study is to determine the feasibility and the effects of a combined pelvic health rehabilitation and exercise fitness program on UI after prostatectomy. The combined exercise program will be delivered both in-person and virtually.

METHODS

This study follows a modified Zelen, two-arm parallel randomized controlled trial design. A total of 106 individuals with PCa will be recruited before prostatectomy surgery. Participants will be randomized between two groups: one receiving usual care and one receiving a combined exercise fitness and intensive pelvic floor muscle training program. Exercise programming will begin 6-8 weeks after prostatectomy and will last 12 weeks. Outcomes include: the 24-h pad test (primary outcome for UI); physical fitness, metabolic indicators, and patient-reported outcomes on erectile function, self-efficacy, severity of cancer symptoms and quality of life. Important timepoints for assessments include before surgery (T0), after surgery (T1), after intervention (T3) and at one-year after surgery (T4).

CONCLUSION

This study will inform the feasibility of offering comprehensive exercise programming that has the potential to positively impact urinary continence, erectile function and cardiometabolic health of individuals undergoing prostatectomy for prostate cancer.

Effect of Pilates combined with pelvic floor muscle training on continence of post-prostatectomy incontinence in patients with different body mass index

BACKGROUND

Urinary incontinence symptoms severely affect older people with different body mass index (BMI).To compare the efficacy of the pelvic floor muscle training (PFMT) in patients with post-prostatectomy incontinence with different BMI.

METHODS

Thirty-seven patients with post-prostatectomy incontinence were included. They were divided into group A (BMI ≤ 25,12), group B (26 ≤ BMI ≤ 30,14), and group C (BMI ≥ 31,11) based on difference BMI. Three groups of patients underwent the same Pilates combined with kegel training. Participants were assessed with 1-hour pad test, the number of incontinence episodes, International Consultation on Incontinence Questionnaire and Oxford Grading Scale.

RESULTS

In the 1-hour pad test, the differences before and after training were statistically significant in all three groups of participants. Group A decreased from 81.83 ± 8.79 to 31.08 ± 5.64 g (P < 0.01). Group B decreased from 80.57 ± 8.87 to 35.85 ± 5.66 g (P < 0.01). Group C decreased from 83.55 ± 10.24 to 40.18 ± 7.01 g (P < 0.01). The number of incontinent episodes in group A decreased from 9.33 ± 1.07 to 3.25 ± 0.62 (P < 0.01). Group B decreased from 8.86 ± 1.09 to 3.79 ± 0.80 (P < 0.01). Group C decreased from 9.27 ± 1.10 to 4.09 ± 0.70 (P < 0.01). The correlation between the three groups of participants and the 1-hour pad test, with an R2 of 0.51. The correlation between the three groups of participants and the number of urinary incontinence episodes with a R2 of 0.43.

CONCLUSIONS

Pelvic floor muscle training can affect the recovery of urinary continence in patients with different BMI. Maintaining a lower BMI can be beneficial for improving urinary control.

Development of Machine Learning Algorithm to Predict the Risk of Incontinence After Robot-Assisted Radical Prostatectomy

Introduction: Predicting postoperative incontinence beforehand is crucial for intensified and personalized rehabilitation after robot-assisted radical prostatectomy. Although nomograms exist, their retrospective limitations highlight artificial intelligence (AI)'s potential. This study seeks to develop a machine learning algorithm using robot-assisted radical prostatectomy (RARP) data to predict postoperative incontinence, advancing personalized care. Materials and Methods: In this propsective observational study, patients with localized prostate cancer undergoing RARP between April 2022 and January 2023 were assessed. Preoperative variables included age, body mass index, prostate-specific antigen (PSA) levels, digital rectal examination (DRE) results, Gleason score, International Society of Urological Pathology grade, and continence and potency questionnaires responses. Intraoperative factors, postoperative outcomes, and pathological variables were recorded. Urinary continence was evaluated using the Expanded Prostate cancer Index Composite questionnaire, and machine learning models (XGBoost, Random Forest, Logistic Regression) were explored to predict incontinence risk. The chosen model's SHAP values elucidated variables impacting predictions. Results: A dataset of 227 patients undergoing RARP was considered for the study. Post-RARP complications were predominantly low grade, and urinary continence rates were 74.2%, 80.7%, and 91.4% at 7, 13, and 90 days after catheter removal, respectively. Employing machine learning, XGBoost proved the most effective in predicting postoperative incontinence risk. Significant variables identified by the algorithm included nerve-sparing approach, age, DRE, and total PSA. The model's threshold of 0.67 categorized patients into high or low risk, offering personalized predictions about the risk of incontinence after surgery. Conclusions: Predicting postoperative incontinence is crucial for tailoring rehabilitation after RARP. Machine learning algorithm, particularly XGBoost, can effectively identify those variables more heavily, impacting the outcome of postoperative continence, allowing to build an AI-driven model addressing the current challenges in post-RARP rehabilitation.

Effectiveness of auricular acupuncture and pelvic floor muscle training in the management of urinary incontinence following surgical treatment for prostate cancer: A randomized clinical trial

PURPOSE

To evaluate the effectiveness of auricular acupuncture combined with pelvic floor muscle training to manage urinary incontinence following radical prostatectomy.

METHODS

This is a randomized clinical trial that was conducted between April 2019 and April 2020 with 60 participants allocated into two groups, namely: control (pelvic muscle training) and intervention (auricular acupuncture + pelvic muscle training). Interventions were carried out during eight weekly sessions. Generalized estimating equations and proportion difference tests were applied in the statistical analysis with a significance level of 0.05.

RESULTS

Urinary incontinence severity decreased between pre-test and post-test in both groups. There was a statistically significant difference of the impact of urinary incontinence on quality of life between the groups at post-test in the domain "severity measures" (p = 0.013), and only in the intervention group between pre-test and post-test in the domains "emotions" (p < 0.001) and "sleep and mood" (p = 0.008). The intervention group was 20.8% (p = 0.007) and 25.3% (p = 0.002) less likely to present nocturia and urinary urgency, respectively.

CONCLUSIONS

Auricular acupuncture combined with pelvic floor muscle training was more effective, compared to pelvic floor muscle training alone, in reducing the impact of urinary incontinence on quality of life and reducing the odds of nocturia and urinary urgency.

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.

What more comprehensive physiotherapy techniques than pelvic floor muscles training should be investigated in the context of post-prostatectomy? A narrative review

BACKGROUND

In a previous article, we have underlined the emerging level of evidence for the effectiveness of a more comprehensive functional physical therapy than solely pelvic floor muscles training (PFMT) for men after radical prostatectomy (RP). More and more authors suggest that physiotherapy programs should not focus only on the side effect of continence, but more generally on the interaction of continence disorders with all other side effects related to patient's physical and emotional functioning.

RESEARCH QUESTION

The aims of this narrative review are to highlight rehabilitation approaches unrelated to analytical PFMT that would seem relevant to consider in the future for post-RP men.

METHOD

Our narrative review sought to map the body of literature relevant to the primary objective (non-PFMT), supplementing the data from our previous review with additional recent articles that were not eligible due to not meeting the inclusion criteria for a systematic review.

RESULTS

After full text screening, 13 interventional studies have been selected. Intervention strategies were based on five major type of exercises: flexibility, synergism & co-activation, coordination & movement control, strength & endurance, aerobic & games therapy. Most of the studies of this narrative review focused on synergies, co-activations and movement control techniques that emphasized the deep abdominal muscles and PFMs reflexive activation. The wide variety of countries represented in the 13 studies with consistent results point to the potential effectiveness and replicability across various socio-cultural, ethnical, or religious contexts.

CONCLUSION

We found 13 studies from 9 different countries that provide a more complete rehabilitation approach than PFMT alone in men post-RP. Intervention strategies were built around five main types of exercises, with the majority of them emphasizing synergies, co-activations, and movement control techniques. In light of these data, we hope that future research will enable us to offer the most relevant and patient-centered physiotherapy treatment.

Urinary continence in high-risk prostate cancer after robot-assisted radical prostatectomy

PURPOSE OF REVIEW

Urinary incontinence is common postoperative complication following robot-assisted radical prostatectomy (RARP) in patients with prostate cancer (PCa). Despite the increasing adoption of RARP in the treatment of high-risk PCa (HRPC), concerns persist regarding the adequacy of reported continence outcomes in this subgroup. This review aims to illuminate the state of continence recovery in HRPC patients post-RARP.

RECENT FINDINGS

Urinary continence (UC) recovery rates in HRPC was reported to be lower than the intermediate/low-risk counterparts from 6 to 24 months post-RARP. Predictive models showed that age, obesity, race, disease status, and surgical approaches represent predictors of continence recovery. Special techniques like NeuroSAFE technique and Retzius-Sparing approach also play a role in reducing incontinence also in the high-risk scenario.

SUMMARY

RARP for HRPC appears to be associated with worse continence compared with other risk groups. A multimodality approach for prediction and prevention of incontinence after RARP is vital. Further research into this area is necessary to enhance continence recovery outcomes in HRPC patients undergoing RARP.

The added value of devices to pelvic floor muscle training in radical post-prostatectomy stress urinary incontinence: A systematic review with metanalysis

PURPOSE

To investigate the role of pelvic floor devices (e.g., biofeedback, electrical stimulation, magnetic stimulation, or their combination) as adjunctive treatments in pelvic floor muscle training (PFMT) in stress urinary incontinence (SUI) after radical prostatectomy.

MATERIALS AND METHODS

A systematic review with meta-analysis. We searched for randomised controlled trials (RCTs) and prospective non-randomised studies investigating the effectiveness of pelvic floor devices as an adjunctive treatment for SUI symptoms assessed with weight pad-test or standardised questionnaires. To assess the risk of bias (RoB) and overall certainty of evidence, the RoB 2.0 or the ROBINS-I, and the GRADE approach were used.

RESULTS

Eleven RCTs met our eligibility criteria. One was at a 'low' RoB, one had 'some concerns', while nine were at a 'high' RoB. Two meta-analyses were conducted to analyse the pooled results of six RCTs included. Specifically, two RCTs reported at week 4 with a 1h pad test a mean difference of 0.64 (95% CI = [-13.09, 14.36]), and four RCTs reported at week 12 with a 24h pad test a mean difference of -47.75 (95% CI = [-104.18, 8.69]). The heterogeneity was high in both analyses (I2 = 80.0%; I2 = 80.6%). The overall level of certainty was very low.

CONCLUSIONS

In line with our results, we cannot conclude whether pelvic floor devices add any value as adjunctive treatment in the management of SUI after radical prostatectomy. Future studies require more comprehensive and standardised approaches to understand whether these devices are effective.

Barriers and facilitators of the implementation of the application of pelvic floor muscle training in patients with prostate cancer: a scoping review

Background

Patients with prostate cancer (PCa) benefit significantly from pelvic floor exercises, but recent results indicate that these exercises have not been fully promoted in clinical settings. This scoping review aimed to identify the facilitators of and barriers to pelvic floor muscle training (PFMT) in PCa survivors.

Methods

A scoping review was conducted in November 2022. Relevant studies were identified from CINAHL, Embase, PubMed, PsycINFO, and Web of Science databases from their inception to 20 November 2022. Data were analyzed and extracted by two formally trained researchers.

Results

A total of 53 studies were included, most of which were randomized controlled trials. The Tailored Implementation for Chronic Diseases (TICD) model framework was used to identify the contents of seven barriers and promotion areas, as well as a series of sub-domains. The most common barriers to implementing pelvic floor muscle training (PFMT) included the following: the lack of a common scheme in guidelines and the measurement of common standardized outcomes, inadequate self-monitoring or feedback from healthcare professionals to improve PFMT compliance, poor patient compliance, and a lack of implementation equipment and financial support. Good treatment effects and easy operation were the facilitators of PFMT.

Conclusion

The implementation of PFMT faces several challenges and opportunities that should be understood thoroughly before implementation. In terms of guidelines and clinical practice, more work is needed, and the possibility of PFMT implementation in various hospitals and community health centers or clinics should be considered.

Research trends of acupuncture therapy on stress urinary incontinence from 1992 to 2022: A bibliometric analysis

Background

Stress urinary incontinence (SUI), the most prevalent type of urinary incontinence disorder, has aroused increasing attention among societies since it has caused much inconvenience in daily life. In addition to conventional conservative treatments like medication and pelvic floor muscle training, acupuncture is now frequently advised. However, a bibliometric analysis of the trend of SUI therapies is still lacking.

Objectives

This article was carried out using CiteSpace (6.3.1) software to research the use of acupuncture therapy on SUI worldwide over the past 30 years (since the database's inception).

Methods

All related articles included were retrieved from the Web of Science Core Collection. CiteSpace (6.3.1) software was used to analyze the number of publications, countries and institutions, authors and cited authors, and burst keywords to assess the hotspots and trends over the previous three decades. And Microsoft Office Excel 2019 was also used for sorting data and generating tables.

Results

The articles were retrieved on August 31, 2022. A total of 108 records with publication dates ranging from 1992 to 2022 were discovered. The annual number of publications generally increased. In the aspect of publication regions, the USA ranked first in centrality, but China had the largest number of publications. The China Academic of Chinese Medical Sciences, Beijing University of Chinese Medicine, and Shanghai University of Traditional Chinese Medicine were the top 3 institutions, according to the institution map. Liu Z (Liu ZS) was the most productive author, and Chen Y ranked first in the centrality. The article published by Liu Z (Liu ZS) in 2017 was the most cited reference. "Bladder neck suspension", "electrical stimulation" and "acupuncture" were popular therapies mentioned among the top ten hot topics. The keywords "therapy", "postprostatectomy incontinence", "muscle", "cell therapy", and "symptom" ranked in the top five on citation burst. The four frontier topics were "efficacy", "symptom", "cell therapy", and "medical technology".

Conclusion

This study illustrated that the application of acupuncture on SUI had an increasing acceptance worldwide. Recent research has concentrated mainly on acupuncture and electroacupuncture, however, there is still not enough literature on these topics. The valuable information was provided for acupuncture researchers to identify prospects including potential collaborators, cooperation institutions, hot themes, and research frontiers.

Efficacy and safety of acupuncture in the treatment of urinary incontinence after prostate surgery: protocol for a systematic review and meta-analysis

BACKGROUND

Urinary incontinence (UI) is a common complication after prostate surgery. Acupuncture treatment (AT) has been proposed as an alternative therapy for this condition. The purpose of this protocol aims to outline a systematic review and meta-analysis that aims to evaluate the effectiveness and safety of AT in patients with postprostate surgery UI.

METHODS

We will search for randomised controlled trials (RCTs) in eight databases including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang database, SinoMed and VIP database. Additionally, we will search two clinical trial registration platforms, namely the WHO's International Clinical Trials Registry Platform and the Chinese Clinical Trial Registry. The search will include articles from the inception of these databases until 30 September 2023. The extracted data will then be imported into the Stata V.15.0 software. Two authors will independently review the literature, collect data and use the Grades of Recommendation, Assessment, Development and Evaluation and the Cochrane Risk of Bias 2 tool to evaluate the risk of bias and the quality of the evidence. Outcomes for RCTs will include at least one of the following: International Consultation Incontinence Questionnaire-Urinary Incontinence Short Form, Individualised Care for People with long-term health conditions-Capability measure for Adults, Score of Frequency Incontinence Quality of Life Questionnaire, Patient Global Impression of Improvement, Visual Analogue Scale, Numeric Rating Scale, 1- hour pad test, Self-Rating Anxiety Scale, total efficiency and adverse event. We will use random or fixed effect models to analyse data according to heterogeneity. If significant heterogeneity exists along with sufficient data, we will perform subgroup analyses to identify the source of heterogeneity.

Pelvic Floor Muscle Training for Urinary Incontinence After Radical Prostatectomy: A Narrative Review

Rehabilitative treatment of urinary incontinence after prostatectomy has showed, on the basis of recent published evidence, encouraging results. At first, clinician applied evaluation and treatment approach suggested based on the studies and rationale of female stress urinary incontinence, but although long term literature suggested no evidence of benefits. Recent studies that have shown the real control mechanisms in male continence through the use of trans-perineal ultrasound, demonstrated that it is not appropriate to transfer the rehabilitation techniques applied in female stress incontinence to male incontinence after prostatectomy. Even that pathophysiology of urinary incontinence after prostatectomy is not fully understood, it's in part attributable to a urethral or bladder source. In particular, however, urethral sphincter dysfunction is predominant, secondary to surgical damage and to the partly organic and partly functional dysfunction of the external urethral sphincter; complementary action of all the muscles capable of contributing to the maintenance of urethral resistance is therefore important. As for rehabilitative approach to post-prostatectomy incontinence, the primary objective is to quantify the residual capacity of the muscular function that must replace the sphincter function, often compromised by surgery. Than a multimodal approach, comprising exercise and instrumental therapies, is needed. The present paper's aim was to overview current urinary dysfunction knowledge for male with radical prostatectomy, and to describe practical issue of evaluation and conservative treatment.

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.

The significance of transrectal ultrasound and urologist_dually guided pelvic floor muscle exercise in improving urinary continence after radical prostatectomy

BACKGROUND

To determine whether transrectal ultrasound and urologist_dually guided pelvic floor muscle exercise is associated with immediate, early and long-term urinary continence after radical prostatectomy.

MATERIALS AND METHODS

Data from 114 patients with localized prostate cancer (PC) who underwent RP at Henan Cancer Hospital from November 2018 to April 2021 were included in the retrospective study. Of the 114 patients, 50 patients in the observation group underwent transrectal ultrasound and urologist_dually guided PFME, and 64 patients in the control group underwent verbally_guided PFME. Contractile function of the external urinary sphincter was in the observation group was evaluated. The immediate, early and long-term urinary continence rates were assessed in both groups, and the factors affecting urinary continence were analyzed.

RESULTS

The urinary continence rate at 2 weeks and 1, 3, 6 and 12 months in the observation group after RP was significantly higher than that in the control group (52.0% vs. 29.7%, 70.0% vs. 39.1%, 82% vs. 57.8, 88% vs. 70.3%, 98.0 vs. 84.4%, p < 0.05). The contractile function of the external urinary sphincter was obviously correlated with urinary continence at multiple visits after RP, except for the 12-month visit. Transrectal ultrasound and urologist-dually guided PFME was verified to be an independent positive factor for urinary continence at 2 weeks and 1, 3, 6 and 12 months using logistic regression analysis. However, TURP was a negative factor for postoperative urinary continence at different times.

CONCLUSIONS

Transrectal ultrasound and urologist_dually guided PFME had a significant role in improving immediate, early and long-term urinary continence after RP and acted as an independent prognostic factor.

Effect of pelvic floor muscle training on urinary incontinence after radical prostatectomy: An umbrella review of meta-analysis and systematic review

OBJECTIVE

To analyse the specific exercise effects of pelvic floor muscle training (PFMT) with or without biofeedback or electrical stimulation on urinary incontinence rehabilitation after radical prostatectomy.

DATA SOURCES

We searched PubMed, Embase, Cochrane Database of Systematic Reviews, Web of Science and Scopus databases for systematic reviews and meta-analyses on PFMT for urinary incontinence after radical prostatectomy from inception to 3 October 2022.

REVIEW METHODS

Two authors independently extracted key data from the included studies. The methodological quality of the included studies was assessed using the A Measure Tool to Assess Systematic Reviews-2 checklist. Grading of Recommendations Assessment Development and Evaluation was used to evaluate the quality of the outcomes.

RESULTS

A total of 18 studies with 29,925 patients were included, all of which were of critically low methodological quality. Biofeedback therapy seemed to show additional benefits compared to PFMT alone; however, the adjunctive role of electrical stimulation remained more controversial due to the lack of strong evidence. Preoperative PFMT sometimes, but not always, showed the potential to improve urinary incontinence. PFMT with the guidance of a therapist could bring some benefits to the patient and was more acceptable to the patient, but consumed some medical resources.

CONCLUSIONS

PFMT has a good effect on improving post-radical prostatectomy incontinence in men, and biofeedback can have an additional beneficial effect on patients, especially in the short-term and medium-term. However, there is insufficient evidence to suggest that electrical stimulation is beneficial for patients with urinary incontinence.

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.

Exploring pelvic floor muscle function in men with and without pelvic floor symptoms: A population-based study

BACKGROUND

Pelvic floor symptoms (PFS), such as lower urinary tract symptoms, defecation disorders, sexual problems, and genital-pelvic pain, are prevalent in men. Thorough physical assessments of the external anal sphincter (EAS) and the puborectal muscle (PRM) are the keys to unraveling the role of muscle dysfunction.

OBJECTIVES

To explore associations within and between the EAS and PRM and between muscle (dys-) function and the number of male PFS.

METHODS

This cross-sectional study purposively enrolled men aged ≥21 years with 0-4 symptoms from a larger study. After extensive external and internal digital pelvic floor assessment, we explored (1) agreement between muscle function of the EAS versus PRM (using cross tabulation), (2) associations within and between the EAS and PRM (using heatmaps), and (3) associations between muscle function and number of PFS (using a visual presentation [heatmaps] and χ²  tests).

RESULTS

Overall, 42 out of 199 men (21%) had completely normal muscle function. Sixty-six (33.2%) had no symptoms, of which 53 (80%) had some degree of muscle dysfunction. No clear dose-response relationship existed between muscle (dys-) function and the number of symptoms. The PRM showed both more dysfunction and severer dysfunction than the EAS.

CONCLUSIONS

No clear association exists between muscle dysfunction and the number of symptoms, and the absence of PFS does not indicate normal muscle function for all men. Dysfunction levels are highest for the PRM. Further pelvic floor muscle research is warranted in men with PFS.

The relationship between pre- and postprostatectomy measures of pelvic floor muscle function and development of early incontinence after surgery

AIMS

The aim of this study is to investigate (i) whether pelvic floor muscle (PFM) shortening can be enhanced by provision of training focused on striated urethral sphincter (SUS) with feedback before prostatectomy, (ii) whether PFM shortening during voluntary efforts and coughing before and after prostatectomy differs between men who do and do not report symptoms of urinary incontinence 1 month after prostatectomy, and (iii) the relationship between severity of incontinence after prostatectomy and features of pelvic floor function (muscle shortening) and urethral length before and after prostatectomy.

METHODS

Sixty men referred for preoperative PFM training before radical prostatectomy participated. The International Continence Society Male Short Form questionnaire was used to quantify continence status. Transperineal ultrasound (US) imaging was used to record pelvic displacements related to activation of striated urethral sphincter, bulbocavernosus (BC) and puborectalis muscles during cough, "natural" voluntary contraction following pamphlet instruction, and trained voluntary contraction after formal physiotherapist instruction including US feedback.

RESULTS

Pelvic floor displacements following training differed between continent and incontinent men; continent participants demonstrated increased SUS shortening after training (compared with "natural"), but no difference was observed between trained and "natural" contractions for incontinent participants. Motion at ano-rectal junction during cough was reduced following surgery, but voluntary and involuntary activation of SUS or BC was not consistently affected by surgery.

CONCLUSIONS

Participants' capacity to improve function of the SUS with training appears related to postprostatectomy continence outcome.

Cross-cultural adaptation and validation of the Urinary Incontinence Scale After Radical Prostatectomy for the Brazilian context

OBJECTIVE

To translate, adapt, and validate the Urinary Incontinence Scale After Radical Prostatectomy for Brazil.

METHOD

Methodological study: cross-cultural adaptation (translation, synthesis, back translation, expert committee (n=25), pre-testing (n=40) and presentation to original authors) and evaluation of measurement properties (n=80). Data were collected between January 2018 and February 2019 in an oncology unit. The calculated measurement properties: structural validity, hypothesis testing, criterion validity and reliability.

RESULTS

The Brazilian version was called Escala de Incontinência Urinária Pós-Prostatectomia Radical. One item was excluded due to low factor loading (0.322). A significant correlation was identified between the total score of the scale and instruments applied (p<0.001). Incontinent men had higher scores on the total scale in relation to continents (p<0.001). Cronbach's alpha was 0.94 and composite reliability was 0.97.

CONCLUSION

The Brazilian version was considered valid and reliable for the assessment of urinary incontinence in prostatectomized patients.

The key role of levator ani thickness for early urinary continence recovery in patients undergoing robot-assisted radical prostatectomy: A multi-institutional study

BACKGROUND

Urinary continence (UC) recovery dramatically affects quality of life after robot-assisted radical prostatectomy (RARP). Membranous urethral length (MUL) has been the most studied anatomical variable associated with UC recovery.

OBJECTIVE

To investigate whether levator ani thickness (LAT), assessed with multi-parametric magnetic resonance imaging (mpMRI), correlates with UC recovery after RARP.

DESIGN, SETTING, AND PARTICIPANTS

The study included 209 patients treated with RARP by expert surgeons with extensive robotic experience from 2017 to 2019. All patients had complete, clinical, mpMRI, pathological, and postoperative data including pelvic floor muscle training (PFMT) protocols.

INTERVENTION

After a radiologist-specific training, two urologists independently examined the files, blinded to clinical and pathological findings as well as to postoperative continence status.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

On mpMRI, LAT, bladder neck (BN) shape, MUL, and apex overlapping (AO) were measured. UC recovery was defined as use of 0 or 1 safety pad at follow-up. Multivariable models were used to assess the association between variables and UC recovery.

RESULTS AND LIMITATIONS

Overall, 173 (82.8%) patients were continent after a median follow-up of 23 months (interquartile range [IQR]: 17-28). Of these, 98 (46.9%) recovered within 3 months after surgery, 42 (20.1%) from 3 to 6 months, and 33 (15.8%) from 6 months onwards. A significant higher rate of patients with LAT > 10 mm (88.1 vs.75.8%; p = 0.03) experienced UC recovery, compared to those with LAT < 10 mm. This difference was observed in the first 3 months after surgery. At multivariable analysis, LAT (odds ratio [OR]: 1.18, 95% confidence interval [CI]: 1.02-1.37; p = 0.02), Preoperative ICIQ score (OR: 0.91, 95% CI: 0.82-0.98, p = 0.03) and PFMT (OR: 1.98, 95% CI: 1.01-3.93; p = 0.04) independently predict higher UC recovery within 3 months, after accounting for age, BMI, preoperative PSA, D'Amico risk group, MUL, BN shape and AO.

CONCLUSIONS

LAT greater than 1 cm was associated with greater UC recovery. Specifically, LAT greater than 1 cm seems to be associated with higher UC rate at 3 months after RARP, compared to those with LAT < 1 cm.

PATIENT SUMMARY

Magnetic resonance features can help in predicting the risk of incontinence after robot-assisted radical prostatectomy and should be taken into account when counseling patients before surgery.

Clinical effect of micturition interruption exercise on urinary incontinence after radical prostatectomy

PURPOSE

To explore the effectiveness of micturition interruption exercise in improving the incidence of urinary incontinence after radical prostatectomy.

MATERIALS AND METHODS

With a retrospective case-control study, 96 patients admitted in the Second Affiliated Hospital of Zhejiang Chinese Medical University from August 2014 to August 2020 and underwent radical prostatectomy were collected as the subjects. Those patients who used micturition interruption exercise (n = 48) were set as the therapy group, and the control group was collected according to the ratio of 1:1; the patients used Kegel exercise (n = 48) to compare the rehabilitation of urinary incontinence in patients and the effect of training compliance on rehabilitation.

RESULTS

The recovery time of urinary incontinence in the therapy group was significantly shorter than that of the control group. In the therapy group, 83.3% of patients with training compliance reached an average or above, while the control group only accounted for 58.3%. International Consultation on Incontinence Questionnaire Short-Form score of the therapy group was lower than that of the control group after surgery. Spearman analysis suggests that there is a negative correlation between the postoperative urinary incontinence recovery time and compliance with the micturition interruption exercise.

CONCLUSIONS

Micturition interruption exercise could not only improve the compliance of patients with exercise, but also significantly shorten the recovery time of urinary incontinence after radical prostatectomy.

The influence of prostatectomy and body position on location and displacement of pelvic landmarks with pelvic floor muscle contraction

AIMS

To compare pelvic floor muscle (PFM) anatomy and function (i) between pre- and post-prostatectomy in standing, and (ii) between sitting and standing postprostatectomy.

METHODS

Thirty-two men scheduled to undergo a prostatectomy volunteered to participate. Transperineal ultrasound imaging was used to visualize five anatomical pelvic landmarks that have been validated to reflex anatomy and activity of PFMs (pubic symphysis, anorectal junction [ARJ], mid-urethra [MU], bulb of penis [BP], and urethrovesical junction [UVJ]). Both before and after prostatectomy, participants performed three submaximal PFM contractions in sitting and/or standing positions while ultrasound data were recorded.

RESULTS

Postprostatectomy the UVJ location was more caudal and dorsal, the ARJ (puborectalis) vector was longer, the BP was more ventral than preprostatectomy, and these landmarks moved less ventrally with contraction. After prostatectomy, the MU, BP, and ARJ were more ventral in standing than sitting. The UVJ was more caudal and elevated more with contraction in standing than sitting after prostatectomy.

CONCLUSION

These data demonstrate differences in the anatomy and mechanics of PFMs post- versus pre-prostatectomy, and between sitting and standing positions postprostatectomy. Findings are consistent with surgical changes to the bladder and urethral anatomy. Reduced passive support for the urethra and bladder are likely to may contribute to differences between standing and sitting postprostatectomy.

Quality Analysis of YouTube Videos Presenting Pelvic Floor Exercises after Prostatectomy Surgery

Background: Prostate cancer (PC) is a major cause of disease and mortality among men. Surgical treatment involving the removal of the prostate may result in temporary or permanent erectile dysfunction (ED) and urinary incontinence (UI), with considerable impact on quality of life. Pelvic floor muscle training (PFMT) is one of the recommended techniques for the prevention, treatment, and rehabilitation of postoperative complications. The aim of this observational study was to assess the quality of YouTube videos—accessible to any patient—related to exercises after prostatectomy surgery. Methods: A systematic search was performed on YouTube on 24 September 2020. One hundred and fifty videos were selected and analyzed. Two statistical analyses were conducted based on machine-learning techniques, and videos were classified as ‘Relevant’ or ‘Non-Relevant’ using Principal Component Analysis (PCA) models. Two reviewers conducted independent analyses. Inter-observer agreement and individual correlations of video data were evaluated with the Intraclass Correlation Coefficient (ICC). Information quality, reliability, and accuracy were measured using the DISCERN Scale and Global Quality Score (GQS), while video popularity was evaluated using the Video Power Index (VPI). Results: DISCERN scored a mean of 3.35 and GQS scored 3.38. Average number of views was 124,354, mean duration was 14:42 min, mean days online was 1777, mean view ratio was 138.30, mean Likes was 1082, mean Dislikes was 68.58, and mean VPI was 92.28. Conclusions: The quality of the videos available on YouTube regarding the recommended pelvic floor exercises in PC surgery, according to the scores obtained, is High. Educational and health institutions, health professionals, government health authorities, and policy makers need to be involved in the proper development of policies to improve the information available on the web in order to have a positive impact on the healthy behavior of the population.

State of the art on stress incontinence management after benign prostatic obstruction surgery

PURPOSE OF REVIEW

Stress urinary incontinence (SUI) is mostly seen after prostate surgery (radical prostatectomy or benign prostatic obstruction [BPO] relief). As new surgical techniques (laser, endoscopic enucleation) have been dramatically expanded in the past decade, a focus on postoperative SUI is necessary to provide the best management in this iatrogenic situation.

RECENT FINDINGS

Surgery is the main option for curative management of SUI after BPO as no oral medication is recommended. Preoperative work-up is mandatory to assess concomitant bladder dysfunction. All available surgical options (peri-urethral injections, periurethral balloons, various male slings, and artificial urinary sphincter) have been studied, but the level of evidence is very low. In this setting, SUI after BPO management is widely inspired from post-PR SUI management, mainly based on clinical experience.

SUMMARY

The available literature regarding persistent SUI after BPO relief is very scarce and further studies are warranted in this specific population.

The repeatability of measurements of male pelvic floor anatomy and function made from transperineal ultrasound images of healthy men and those before and after prostatectomy

AIMS

To investigate the inter- and intratester repeatability of measurement of the location and displacement of five pelvic landmarks related to pelvic floor muscles with transperineal ultrasound (TPUS) imaging recorded from healthy men and men before and after prostatectomy.

METHODS

TPUS images were selected from four different participant groups: healthy men, men awaiting prostatectomy, men 2 weeks after prostatectomy, and men 12 months after prostatectomy. On two separate occasions, two assessors with different levels of experience performed analysis of location and displacement of five pelvic landmarks in images made at rest and during voluntary contraction. A two-way mixed effects, single measurement, absolute agreement intraclass correlation coefficient (ICC) was used to investigate the repeatability.

RESULTS

Intertester reliability of all locations at rest for all groups was excellent (ICCs > 0.8) except for the craniocaudal coordinate of the ventral urethrovesical junction for men 2 weeks postprostatectomy and the anorectal junction for men with a cancerous prostate. Intertester reliability of the measurement of landmark displacement was acceptable (>0.5) for the dorsoventral axis of motion but not for the craniocaudal axis of motion for all landmarks across all groups. The more experienced assessor was consistently more repeatable. More deeply placed landmarks were more often excluded from analysis and had poorer reliability.

CONCLUSIONS

Analysis of TPUS images across clinical groups is repeatable for both location and displacement of pelvic landmarks related to pelvic floor muscles when measures are made twice. Analysis experience, landmark depth and optimization of ultrasound settings appear to be important factors in reliability.

Physiotherapy and pelvic floor health within a contemporary biopsychosocial model of care: From research to education and clinical practice

Background

Pelvic floor dysfunction (PFD) is a common problem in both men and women. Despite the high prevalence and negative effects on quality of life, there is still a lack of research in this area which translates into clinical practice and education.

Objectives

My study discusses how gaps and controversies in current research and evidence on PFD might be addressed by positioning PFD within a contemporary biopsychosocial model of care (BPSM).

Method

Various databases were searched for relevant studies published between 2010 and 2020 to support hypotheses and statements.

Results

My study focuses on the available evidence of PFD in both men and women as related to the themes and sub-themes of the BPSM, and how this available evidence might translate into education and clinical practice. It highlights areas of research, education and clinical practice that need to be explored and how the different components of healthcare may influence one another.

Conclusion

Biomedical aspects regarding pelvic health are mostly investigated and taught, whilst psychological, cognitive, behavioural, social and occupational factors, individualised care, communication and therapeutic alliances are still under-investigated and not integrated or translated at a sufficient level into research, education and clinical practice.

Clinical implications

Incorporating the integration of all factors of the BPSM into research is important for effective knowledge translation and enhancement of a de-compartmentalised approach to management. The interaction between the different components of the BPSM should be investigated especially in a South African population.

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.

Analysis of conventional versus advanced pelvic floor muscle training in the management of urinary incontinence after radical prostatectomy: a systematic review and meta-analysis of randomized controlled trials

Background

The underutilization of additional supportive muscles is one of the potential reasons for suboptimal efficacy of conventional pelvic floor muscle training (CPFMT). The present study concentrates on any advantage of advanced pelvic floor muscle training (APFMT) in patients with urinary incontinence (UI) after radical prostatectomy (RP).

Methods

Literature search was conducted on PubMed, Embase, Cochrane Library and Web of Science from database inception to February 2020. The data analysis was performed by the Cochrane Collaboration's software RevMan 5.3.

Results

Both APFMT and CPFMT groups indicates superiority over baseline in terms of pad number, the International Consultation on Incontinence Questionnaire—Short Form (ICIQ-SF) score, pad weight at short-term follow-up, and PFME and PFMS at intermediate-term follow-up. No adverse events were reported in all included studies. Patients receiving APFMT had a similar attrition rate to those receiving CPFMT (18/236 vs. 22/282, P=0.61). Compared to CPFMT group, APFMT group provided intermediate-term advantages in terms of pad number (MD: −0.75, 95% CI: −1.36 to −0.14; P=0.02), ICIQ-SF score (MD: −3.79, 95% CI: −5.89 to −1.69; P=0.0004), PFME (MD: 1.93, 95% CI: 0.99 to 2.87; P<0.0001) and pad weight (MD: −1.40, 95% CI: −1.70 to −1.00; P<0.00001).

Conclusions

Current evidence indicated that APFMT might facilitate the recovery of UI after RP according to intermediate-term advantages over CPFMT in terms of pad number, ICIQ-SF score, PFME and pad weight. Further standardized, physiotherapist-guided and well-designed clinical trials conducted by large multicenter and experienced multidisciplinary clinicians are still warranted.

Pelvic Floor Muscle Training in Radical Prostatectomy and Recent Understanding of the Male Continence Mechanism: A Review

OBJECTIVE

Pelvic floor muscle training (PFMT) is recommended as part of supportive care for patients with prostate cancer. It can assist in reducing treatment-related symptoms such as urinary incontinence. This literature review aims to discuss recent innovative findings on the pathophysiology of the male continence mechanism and implications for PFMT in radical prostatectomy.

DATA SOURCES

CINAHL, Embase, Web of Science, Emcare and PsycINFO were searched until January 2020.

CONCLUSION

Nurses providing supportive care for patients undergoing radical prostatectomy can engage in-clinic in the instruction and recommendation of pre- and postoperative PFMT and delivering guidance on home-based programs to promote motor learning.

IMPLICATIONS FOR NURSING PRACTICE

Optimal postoperative urinary incontinence outcomes are suggested to be promoted by preoperative PFMT. Training focused on the urethral and anterior pelvic floor muscle complex has been shown to facilitate mid urethral occlusion required for continence. Prescription of PFMT should be individualised, focusing on skill acquisition and motor learning, which is in line with recent knowledge developments in male pelvic floor anatomy.

Pelvic floor muscle exercise with biofeedback helps regain urinary continence after robot-assisted radical prostatectomy

Background

To determine the benefit of pelvic floor muscle exercise (PFME) with visual biofeedback on promoting patient recovery from incontinence, we investigated variables associated with the early restoration of continence for patients who robot-assisted radical prostatectomy (RARP).

Methods

Of the 83 patients enrolled, 41 consecutive patients completed PFME (the exercise group), and the other 42 consecutive patients just before the PFME program commenced (the control group). The primary outcome was whether PFME engagement was associated with zero pad continence restoration within 3 months of surgery.

Results

Continence restoration percentages (defined as zero pads used per day) at 1, 3, and 6 months after surgery were 49.4%, 77.1%, and 94.0%, respectively. The exercise group achieved significantly higher recovery rates at 1 month (p=0.037), 3 months (p<0.001), and 6 months (p=0.023). Cox regression analysis demonstrated that a lower Gleason score (<8; hazard ratio [HR], 2.167), lower prostate specific antigen (<20 ng/dL; HR, 2.909), and engagement in PFME (HR, 3.731) were independent predictors of early recovery from postprostatectomy incontinence. Stratification by age showed that those younger than 65 years did not benefit significantly from exercise (log-rank test, p=0.08), but that their elderly counterparts, aged 65–70 years (p=0.007) and >70 years old (p=0.002) benefited significantly.

Conclusion

This study suggests that postoperative engagement in PFME with biofeedback speeds up the recovery of continence in elderly patients (≥65 years old) that undergo RARP.

Conservative management of urinary incontinence following robot-assisted radical prostatectomy

INTRODUCTION

Robotic assisted radical prostatectomy (RARP) is getting more and more popular becoming the most common radical prostatectomy technique. Unfortunately, a not negligible proportion of patients in whom RARP is performed experience urinary incontinence. We aimed to systematically review the current literature evidence on urinary incontinence conservative treatment after RARP.

EDIDENCE AQUISITION

A systematic literature review search using PubMed (Medline), Scopus, and Web of Science databases was performed in December 2019. PRISMA guidelines have been adopted. Population consisted of patients with urinary incontinence after RARP (P), conservative intervention was considered of interest (I). No comparator was considered mandatory (C). Outcomes of interest were the recovery of continence and quality of life (O).

EVIDEDENCE SYNTHESIS

Six studies were included. Four of them investigated the use of pelvic floor muscle training (PFMT). PFMT improved pelvic muscle strength. Continence recovery was faster when guided PFMT was adopted. Moreover, two studies tested the effect of solifenacin on urinary incontinence. One of them, a randomized clinical trial, failed to show shorter time to continence in solifenacin group compared to placebo.

CONCLUSIONS

The use of pads is associated with a detrimental effect on quality of life thus active treatments for UI post-RARP are warranted. PFMT has the main advantage to shorten the time for recovery. The use of solifenacin seems to not offer striking advantages in UI following RARP. Future studies should focus on testing the efficacy of these treatments when used after robotic vs. open radical prostatectomy.

Effect of the Nurse-Led Sexual Health Discharge Program on the Sexual Function of Older Patients Undergoing Transurethral Resection of Prostate: A Randomized Controlled Trial

Background: Sexual dysfunction is a complication of transurethral resection of prostate (TURP). There is a lack of knowledge of the effect of discharge programs aiming at improving sexual function in older patients undergoing TURP. Objective: To investigate the effect of the nurse-led sexual health discharge program on the sexual function of older patients undergoing TURP. Methods: This randomized controlled clinical trial was conducted on 80 older patients undergoing TURP in an urban area of Iran. Samples were selected using a convenience method and were randomly assigned into intervention and control groups (n = 40 in each group). The sexual health discharge program was conducted by a nurse in three sessions of 30-45 min for the intervention group. Sexual function scores were measured using the International Index of Erectile Function (IIEF) Questionnaire, one and three months after the intervention. Results: The intervention significantly improved erectile function (p = 0.044), sexual desire (p = 0.01), satisfaction with sexual intercourse (p = 0.03), overall satisfaction with sexual function (p = 0.01), and the general score of sexual function (p = 0.038), three months after the program. In the first month after the intervention, except in sexual desire (p = 0.028), no statistically significant effect of the program was reported (p > 0.05). Conclusion: The nurse-led sexual health discharge program led to the improvement of the sexual function of older patients undergoing TURP over time. This program can be incorporated into routine discharge programs for the promotion of well-being in older patients.

Influence of body position on dynamics of the pelvic floor measured with transperineal ultrasound imaging in men

AIMS

This paper aims to evaluate the feasibility of transperineal ultrasound imaging (TPUS) for visualizing the motion of pelvic landmarks associated with striated pelvic floor muscle contraction in men in standing; to compare the locations of pelvic landmarks between sitting and standing; and to compare the effects of different body positions on measures of pelvic floor muscle contraction.

METHODS

Thirty-five men awaiting prostatectomy volunteered to participate. Participants performed three repetitions of submaximal pelvic floor contraction in sitting and again in standing. Movement of pelvic landmarks with contraction was recorded using an ultrasound imaging transducer placed on the perineum.

RESULTS

The feasibility of TPUS in men in standing was demonstrated through the visualization of three out of four pelvic landmarks in more than 95% of images in the standing position. Analysis of pelvic landmarks and their respective relationships with muscle shortening demonstrated that the anorectal junction and urethrovesical junction were lower and the estimated length of puborectalis was shorter in standing than sitting. The mid-urethra (striated urethral sphincter) and anorectal junction (puborectalis) landmark displaced further cranially in standing than sitting.

CONCLUSIONS

TPUS can be used to visualize three pelvic landmarks in men with cancerous prostates. Puborectalis is shorter at rest in standing than sitting, and elevation of the mid-urethra and the anorectal junction is more in standing than sitting. Together these findings indicate that feedback for pelvic floor muscle training is possible in both positions, but the position needs to be standardized for a comparative assessment.

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.
