Early Continence Recovery after Robot-Assisted Radical Prostatectomy: A Multicenter Analysis on the Role of Prostatic Shape

Aim: The aim of the study was to investigate the relationship between prostatic apical shape and continence recovery after robot-assisted radical prostatectomy (RARP) in a large multicentric cohort. Materials and Methods: Data of patients who underwent transperitoneal RARP at 10 referral robotic centers between January 2017 and December 2022 were retrospectively analyzed. Patients were stratified into four groups based on the multiparametric magnetic resonance imaging (mpMRI) prostatic apex shape. Pre-, intra-, and postoperative variables were compared. Continence recovery was defined as no pad or 1 safety pad/day. Results: A total of 822 patients were retrieved and classified as Group A (n = 206), Group B (n = 221), Group C (n = 143), and Group D (n = 252) based on the mpMRI. At baseline, statistically significant differences were found in Charlson's comorbidity index (CCI) (p < 0.001), body mass index (BMI) (p = 0.01), prostatic urethral length (p = 0.008), and membranous urethral length (p = 0.03). In terms of bladder neck-sparing technique, a statistically significant difference was found among groups (p = 0.005). Group D achieved continence significantly earlier than the other groups after RARP, with a median recovery time of 3 months (95% confidence interval [CI]: 3-3), compared with 4 months for all other groups (95% CI: 4-4). Group D showed an earlier continence recovery after RARP with respect to all the other shapes (hazard ratio [HR] = 1.23, 95% CI: 1.05-1.43, p = 0.005). The estimated HR remained unchanged after adjusting by age, BMI, CCI, bladder neck-sparing, nerve-sparing, and presence of median lobe (HR = 1.17, 95% CI: 1.00-1.38, p = 0.046). Cox model showed an association with BMI (HR = 0.97, 95% CI: 0.95-0.99, p = 0.03), bladder neck-sparing (HR = 1.45, 95% CI: 1.24-1.70, p < 0.001), and nerve-sparing (HR = 1.27, 95% CI: 1.11-1.46, p = 0.001). Conclusions: Our multi-institutional study confirmed that prostatic apical shape has a significant impact on time-to-continence after RARP.

Surgical experience overcomes the impact of prostatic-urethral anatomy on continence recovery after robotic prostatectomy: comprehensive analysis on 366 cases

PURPOSE

To investigate the relationship between a set of prostate-urethral complex (PUC) measurements and incontinence after robot-assisted radical prostatectomy (RARP).

METHODS

The study included data from patients undergoing RARP performed by 2 expert surgeons between 2019 and 2022, with data about preoperative magnetic resonance imaging (MRI) and functional follow-up. Continence status was assessed according to a stringent definition (no PADS used). MRIs were evaluated to calculate prostatic urethral length, membranous urethral length, membranous urethral width, levator ani thickness, and prostate shape. The association of PUC measurements with continence after RARP was studied. Secondarily, we evaluated whether pre-determined cut-off values of PUC measurements could be associated with time to continence. Cumulative hazard incidence analysis was performed by the Nelson-Aalen hazard function. Cumulative incidence hazard curves were built; the Peto-Peto test was used to evaluate the difference among the curves.

RESULTS

366 patients were included. At the 12-month follow-up, 333 patients (90.1%) were continent. Classification of PUC measurements overlapped between continent and noncontinent patients. However, a statistically significant difference was observed for levator ani thickness, greater in continent patients (12.8 mm vs. 11.7; p = 0.02). Multivariable models found BMI as independent predictor of incontinence (HR 1.04, 95% C.I 1.00-1.07, p = 0.04). None of PUC measurements associated with incontinence. Also, cumulative hazard incidence analysis at 3 / 6 / 12-months found no statistically significant difference in PUC measurements.

CONCLUSION

No association was found between anatomical characteristics of PUC and continence or time to continence after RARP performed by proficient surgeons. Our data would suggest that once the surgeon has surpassed the learning curve, anatomical variations do not significantly affect the appropriate and proficient execution of the prostate apex dissection during RARP.

Factors Contributing to Early Recovery of Urinary Continence Following Radical Prostatectomy: A Narrative Review

Stress urinary incontinence (SUI) is a common condition in patients following radical prostatectomy (RP), which has a significant impact on all aspects of quality of life and is associated with significant social stigma. The factors that improve urinary incontinence in patients following surgery remain controversial. The aim of our narrative review was to identify and synthesise the latest evidence on pre-, intra- and post-operative factors and predictors that contribute to early continence recovery after RP. In this narrative review, primary resources were identified by searching PubMed, EMBASE and Medline, and secondary resources were collected by cross-referencing citations in the relevant articles. We started our review by searching for systematic reviews of factors and predictors that contribute to early recovery of urinary continence after RP. We then reviewed societal guidelines such as the American Urological Association and European Urological Association guidelines on male urinary incontinence. This review focuses on the pre-, intra and postoperative factors that influence postoperative SUI after RP, as well as highlighting modifications in surgical techniques that lead to early continence recovery. Increasing age, higher BMI, shorter membranous urethral length (MUL), and larger PV are independent prognostic factors for SUI within 3 months after RP. Factors such as modified surgical technique preservation of anatomical structure lead to influence postoperative early continence recovery. SUI after RP is influenced by various factors. These factors include not only anatomical landmarks and patient-related factors such as age, BMI, length of MUL and prostate volume, but also prior transurethral resection or laser enucleation of the prostate, the surgeon's expertise, the surgical approach and NS technique.

Impact of Intraoperative Prognostic Factors on Urinary Continence Recovery Following Open and Laparoscopic Radical Prostatectomy

Background and Objectives: Radical prostatectomy (RP) stands as the predominant instigator of postoperative stress urinary incontinence. Techniques such as the preservation of the neurovascular bundles, bladder neck preservation, and ensuring longer postoperative urethral length have shown positive impacts on continence. The posterior reconstruction is another method that aids in early continence recovery. Anterior suspension as simulator of puboprostatic ligaments is another factor. Materials and Methods: This study was conducted in the Clinic of Urology, University Clinical Center of Serbia, between December 2014 and January 2020, employing a prospective, non-randomized comparative design. Data were meticulously gathered from 192 consecutive patients. The process of regaining continence was monitored at intervals of 1, 3, 6, 12, and 24 months after surgery. The main criterion for assessing the level of urinary continence was the number of pads used daily. Results: The distribution of overall continence rates in the BNP vs. no-BNP group at 3, 6 and 12 months was 86% vs. 60% (p < 0.0001), 89% vs. 67% (p < 0.0001), 93% vs. 83% (p = 0.022). Continence rates in non-posterior reconstruction group (10%, 22%, 34%, and 54% at 1, 3, 6, and 12 months) were statistically significantly lower (p < 0.0001). The patients who underwent urethral suspension exhibited significantly higher rates of overall continence at 1 mo (73% vs. 29%, p < 0.0001), 3 mo (85% vs. 53%, p < 0.001), 6 mo (89% vs. 62%, p < 0.0001), 12 mo (95% vs. 76%, p < 0.0001), and 24 mo (93% vs. 81%, p = 0.007). Patients who underwent urethral suspension had a four-fold greater likelihood of regaining continence (p = 0.015). Conclusions: Patients who underwent urethral suspension or BNP or posterior reconstruction had higher continence rates. Only the urethral suspension was found to be a significant prognostic factor of continence recovery.

Prevalence and risk factors for overactive bladder symptoms in patients with artificial urinary sphincter

To demonstrate the prevalence and risk factors for overactive bladder symptoms associated with artificial urinary sphincter implantation, we investigated the patients who underwent primary artificial urinary sphincter implantation with severe urinary stress incontinence. Forty-eight patients who completely answered the questionnaires of the overactive bladder symptom score before surgery were included. Patient characteristics, urinary status at pre and 1, 3, 6, and 12 months post-device activation, and predictive factors for overactive bladder symptoms were examined. Sixty percent of the patients had preoperative overactive bladder symptoms. Until 12 months after device activation, 35-40% of all patients had overactive bladder symptoms. The rate of persistent and de novo postoperative overactive bladder symptoms was 44.8% and 26.3%, respectively. Daily pad use was not different between patients w/wo overactive bladder symptoms. The only risk factor for postoperative overactive bladder symptoms was a max cystometoric capacity < 200 mL measured by a preoperative urodynamic study. Attention must be given to both persistent and de novo overactive bladder symptoms associated with artificial urinary sphincter implantation for patients with stress incontinence. Counsel should equally be provided for preoperative overactive bladder symptoms, especially in cases with a cystometric capacity < 200 mL.

Early recovery of urinary continence after robot-assisted radical prostatectomy is associated with membranous urethra and neurovascular bundle preservation

OBJECTIVES

We investigated the correlation between surgical outcomes and postoperative urinary continence recovery in robot-assisted radical prostatectomy (RARP).

METHODS

Patients who underwent RARP in our institution (n = 195) were included in this study. Preserved urethral length (PUL) was assessed during the procedure. Other outcomes of the surgical procedure were collected from operative records. Kaplan-Meier analysis with log-rank test was used to compare urinary continence recovery rate with the PUL, sparing of the neurovascular bundle (NVB), and other surgical procedures. Univariate and multivariate analyses were performed using Cox proportional hazards model, and p-values of <0.05 were considered significant.

RESULTS

Patients with a PUL ≥26 mm had 10.0%, 24.7%, 36.6%, and 89.0% continence recovery rates at 30, 60, 90, and 365 days after surgery, respectively, while patients with a PUL <26 mm had 0%, 17.8%, 26.1%, and 80.9% recovery rates, respectively. Kaplan-Meier curves showed significantly better postoperative urinary continence recovery at 30 days after RARP in patients with a PUL ≥26 mm than those with a PUL <26 mm (p = 0.0028) and in patients with NVB preservation than those with no NVB preservation (p = 0.014). Urinary continence recovery within 30, 60, and 90 days after surgery was 90.6% for patients with a PUL of ≥26 mm and NVB preservation, while only 82.3% for patients with a PUL of <26 mm or no NVB preservation.

CONCLUSION

Our results suggest that a PUL ≥26 mm and NVB preservation after RARP correlate with a significantly higher postoperative rate of recovery of urinary continence.

Understanding long-term continence rates after robot-assisted laparoscopic prostatectomy - one-year follow-up on "Cognitive ability as a non-modifiable risk factor for post-prostatectomy urinary incontinence"

Purpose

To evaluate long-term continence rates (12 months) in patients after robot-assisted laparoscopic prostatectomy (RALP) in relation to their cognitive ability (CoAb), which proved to be a predictor for early post-prostatectomy incontinence.

Material & Methods

This is the 12-month follow-up evaluation of our previously published observational single-center, prospective evaluation of 84 patients who underwent RALP as treatment of their localized prostate cancer between 07/2020 and 03/2021. Post-prostatectomy incontinence (PPI) was measured by asking patients about their 24 h pad usage, whereby 0 pads were considered continent and ≥1 pad was considered incontinent. CoAb was evaluated by performing the Mini-Mental State Examination prior to surgery. Possible predictors for PPI were evaluated using univariate and multivariable logistic regression models.

Results

Multivariable logistic regression analyses identified early incontinence status and nerve sparing (NS) as independent predictors for PPI after 12 months, resulting in a 5.69 times higher risk for PPI when the loss of urine was between 10 and 50 ml during the early performed pad test (one day after catheter removal) compared to 0-1 ml loss of urine [95% confidence interval (CI): 1.33-28.30, p = 0.024] and a 6.77 times higher risk for PPI, respectively, when only unilateral NS was performed compared to bilateral NS (95% CI: 1.79-30.89, p = 0.007). CoAb lost its predictive value for long-term PPI (p = 0.44).

Conclusion

The results of this study suggest that PPI is a dynamic, rather than a static condition with a dynamically changing pathophysiology within the first 12 months after RALP. Coping methods and therapies should adapt to this circumstance.

The role of preoperative prostatic shape in the recovery of urinary continence after robotic radical prostatectomy: a single cohort analysis

BACKGROUND

To explore the role of preoperative MRI prostate shape in urinary incontinence after robot-assisted radical prostatectomy (RARP).

METHODS

Patients were stratified into four groups based on the mpMRI prostatic apex shape: Group A (prostatic apex overlapping the membranous urethra anteriorly and posteriorly), Group B and C (overlap of the prostatic apex of the anterior or posterior membranous urethra, respectively) and Group D (no overlap). Preoperative variables and intraoperative data were compared. Continence recovery was defined as no pad/day or 1 safety pad/day by an outpatient evaluation performed at 1, 3, 6, and 12 months after RARP.

RESULTS

One hundred patients underwent RARP were classified as belonging to Group A (n = 30), Group B (n = 16), Group C (n = 14), and Group D (n = 40). Group D showed a significantly more favorable urinary continence recovery after RARP respect to all the other shapes presenting any forms of overlapping (HR = 1.9, 95% CI 1.2-3.1, p = 0.007). The estimated HR remained substantially unchanged after adjusting by age, body mass index, CCI, prostate volume, and bladder neck sparing (HR = 1.9, 95% CI 1.1-3.2, p = 0.016). The continence recovery median time was 9 months for Group A + B + C (95% CI 5-11) and 4 months for Group D (95% CI 2-6) (p = 0.023).

CONCLUSION

Shape D showed a better continence recovery when compared to other shapes presenting any kind of overlapping of the prostatic apex over the membranous urethra.

Effect of precise nursing service mode on postoperative urinary incontinence prevention in patients with prostate disease

BACKGROUND

Patients with benign prostatic disease often experience detrusor morphological changes and dysfunction. In severe cases, it leads to bladder detrusor dysfunction, resulting in dysuria, frequent urination, urgent urination, incomplete urination, and other symptoms including renal function injury. An operation to restore normal urination function and to control postoperative complications, as far as possible, is the most common method for benign prostatic disease.

AIM

To observe the effect of precise nursing service mode on postoperative urinary incontinence prevention in patients with prostate disease.

METHODS

In total, 130 patients diagnosed with benign prostatic disease, from January 2018 to June 2021, in our hospital, were selected and divided into observation and control groups according to their treatment options. Sixty-five cases in the control group were given routine nursing mode intervention and 65 cases in the observation group received precise nursing service mode intervention. The intervention with the observation group included psychological counseling about negative emotions, pelvic floor exercises, and post-hospital discharge care. The complications of the two groups were counted, and the general postoperative conditions of the two groups were recorded. The urinary flow dynamics indexes of the two groups were detected, and differences in clinical international prostate system score (IPSS) and urinary incontinence quality of life questionnaire (I-QOL) scores were evaluated.

RESULTS

Postoperative exhaust time (18.65 ± 3.23 h and 24.63 ± 4.51 h), the time of indwelling catheter (4.85 ± 1.08 d and 5.63 ± 1.24 d), and hospitalization time (8.78 ± 2.03 d and 10.23 ± 2.28 d) in the observation group were lower than in the control group. The difference was statistically significant (P < 0.05). After the operation, the maximum urinary flow rate (Qmax) increased (P < 0.05), the residual urine volume (RUV) decreased (P < 0.05), and the maximum closed urethral pressure (MUCP) was not statistically significant (P > 0.05) compared to pre-operation. The Qmax of the observation group was higher than that of the control group, while the RUV was lower than that of the control group. There was no significant difference in MUCP between the observation and control groups (P > 0.05). The I-QOL score of the two groups improved (P < 0.05), and the IPSS decreased (P < 0.05). After the operation, the I-QOL score of the observation group was higher than that of the control group, and the IPSS was lower than that of the control group (P < 0.05). There were no significant differences in the incidence of urethral injury (1.54% and 3.08%), bladder spasm (0.00% and 1.54%), and secondary bleeding (1.54% and 4.62) between the observation and control groups (P > 0.05).

CONCLUSION

The precise nursing service mode can reduce the incidence of postoperative urinary incontinence in patients with prostate disease, thus improving postoperative urodynamics and rehabilitation, and quality of life.

Evaluation of prostate volume in mpMRI: comparison of the recommendations of PI-RADS v2 and PI-RADS v2.1

PURPOSE

We aimed to evaluate the prostate volumes calculated as recommended in the PI-RADS v2 and PI-RADS v2.1 guidelines, intraobserver and interobserver variability, and the agreement between the two measurement methods.

METHODS

Prostate mpMRI examinations of 114 patients were evaluated retrospectively. T2-weighted sequences in the axial and sagittal planes were used for the measurement of the prostate volume. The measurements were performed by two independent observers as recommended in the PI-RADS v2 and PI-RADS v2.1 guidelines. Both observers conducted the measurements twice and the average values were obtained. In order to prevent bias, the observers carried out measurements at one-week intervals. In order to assess intraobserver variability, observers repeated the measurements again at one-week intervals. The prostate volume was calculated using the ellipsoid formula (W×H×L×0.52).

RESULTS

Intraclass correlation coefficient (ICC) revealed almost perfect agreement between the first and second observers for the measurements according to both PI-RADS v2 (0.93) and PI-RADS v2.1 (0.96) guidelines. The measurements were repeated by both observers. According to the ICC values, there was excellent agreement between the first and second measurements with respect to both PI-RADS v2 and PI-RADS v2.1 for first (0.94 and 0.96, respectively) and second observer (0.94 and 0.97, respectively). For both observers, the differences had a random, homogeneous distribution, and there was no clear relationship between the differences and mean values.

CONCLUSION

The ellipsoid formula is a reliable method for rapid assessment of prostate volume, with excellent intra- and interobserver agreement and no need for expert training. For the height measurement, the recommendations of the PIRADS v2.1 guideline seem to provide more consistently reproducible results.

Patient- and Tumour-related Prognostic Factors for Urinary Incontinence After Radical Prostatectomy for Nonmetastatic Prostate Cancer: A Systematic Review and Meta-analysis

CONTEXT

While urinary incontinence (UI) commonly occurs after radical prostatectomy (RP), it is unclear what factors increase the risk of UI development.

OBJECTIVE

To perform a systematic review of patient- and tumour-related prognostic factors for post-RP UI. The primary outcome was UI within 3 mo after RP. Secondary outcomes included UI at 3-12 mo and ≥12 mo after RP.

EVIDENCE ACQUISITION

Databases including Medline, EMBASE, and CENTRAL were searched between January 1990 and May 2020. All studies reporting patient- and tumour-related prognostic factors in univariable or multivariable analyses were included. Surgical factors were excluded. Risk of bias (RoB) and confounding assessments were performed using the Quality In Prognosis Studies (QUIPS) tool. Random-effects meta-analyses were performed for all prognostic factor, where possible.

EVIDENCE SYNTHESIS

A total of 119 studies (5 randomised controlled trials, 24 prospective, 88 retrospective, and 2 case-control studies) with 131 379 patients were included. RoB was high for study participation and confounding; moderate to high for statistical analysis, study attrition, and prognostic factor measurement; and low for outcome measurements. Significant prognostic factors for postoperative UI within 3 mo after RP were age (odds ratio [OR] per yearly increase 1.04, 95% confidence interval [CI] 1.03-1.05), membranous urethral length (MUL; OR per 1-mm increase 0.81, 95% CI 0.74-0.88), prostate volume (PV; OR per 1-ml increase 1.005, 95% CI 1.000-1.011), and Charlson comorbidity index (CCI; OR 1.28, 95% CI 1.09-1.50).

CONCLUSIONS

Increasing age, shorter MUL, greater PV, and higher CCI are independent prognostic factors for UI within 3 mo after RP, with all except CCI remaining prognostic at 3-12 mo.

PATIENT SUMMARY

We reviewed the literature to identify patient and disease factors associated with urinary incontinence after surgery for prostate cancer. We found increasing age, larger prostate volume, shorter length of a section of the urethra (membranous urethra), and lower fitness were associated with worse urinary incontinence for the first 3 mo after surgery, with all except lower fitness remaining predictive at 3-12 mo.

Current Management of Post-radical Prostatectomy Urinary Incontinence

Prostate cancer is the second most common cancer in men worldwide. Radical prostatectomy and radiation beam therapy are the most common treatment options for localized prostate cancer and have different associated complications. The etiology of post prostatectomy incontinence is multifactorial. There is evidence in the literature that anatomic support and pelvic innervation are important factors in the etiology of post-prostatectomy incontinence. Among the many surgical and technical factors proposed in the literature, extensive dissection during surgery, damage to the neurovascular bundle and the development of postoperative fibrosis have a substantial negative impact on the continence status of men undergoing RP. Sparing of the bladder neck and anterior, and possibly posterior, fixation of the bladder-urethra anastomosis are associated with better continence rates. Overactive bladder syndrome (OAB) is multifactorial and the exact role of prostate surgery in the development of OAB is still under debate. There are several variables that could contribute to detrusor overactivity. Detrusor overactivity in patients after radical prostatectomy has been mainly attributed to a partial denervation of the bladder during surgery. However, together with bladder denervation, other hypotheses, such as the urethrovesical mechanism, have been described. Although there is conflicting evidence regarding the importance of conservative treatment after post-prostatectomy urinary incontinence, pelvic floor muscle training (PFMT) is still considered as the first treatment choice. Duloxetin, either alone or in combination with PFMT, may hasten recovery of urinary incontinence but is often associated with severe gastrointestinal and central nervous side effects. However, neither PFMT nor duloxetine may cure male stress urinary incontinence. The therapeutic decision and the chosen treatment option must be individualized for each patient according to clinical and social factors. During the recent years, the development of new therapeutic choices such as male sling techniques provided a more acceptable management pathway for less severe forms of urinary incontinence related to radical prostatectomy. Following this perspective, technological improvements and the emergence of new dedicated devices currently create the premises for a continuously positive evolution of clinical outcomes in this particular category of patients.

Anastomosis quality score during robot-assisted radical prostatectomy: a new simple tool to maximize postoperative management

PURPOSE

The urethro-vesical anastomosis represents one of the most challenging steps of robotic prostatectomy (RARP). To maximize postoperative management, we specifically designed our anastomosis quality score (AQS), based on the intraoperative characteristics of the urethra and bladder neck.

METHODS

This is a prospective study, conducted from April 2019 to March 2020. All the patients were classified into three different AQS categories (low, intermediate, high) based on the quality of the anastomosis. The postoperative management was modulated accordingly.

RESULTS

We enrolled 333 patients. According to AQS, no differences were recorded in intraoperative complications (p = 0.9). Median hospital stay and catheterization time were longer in AQS 1 group (p < 0.001). Additionally, the occurrence of postoperative complication was higher in AQS 1 category (p = 0.002) but, when focusing on the complications related to the quality of the anastomosis, no differences were found neither for acute urinary retention (p = 0.12) nor urine leakage (p = 0.11). Finally, concerning the continence recovery, no significant differences were found among the three groups for each time point. The highest potency recovery rate at one month of follow-up was recorded in AQS 3 category (p = 0. 03).

CONCLUSION

The AQS proposed revealed to be a valid too to intraoperatively categorize patients who underwent RARP on the basis of the urethral and bladder neck features. The modulated postoperative management for each specific score category allowed to limit the occurrence of complications and to maximize the functional outcomes.

Outcomes of a Series of Patients with Post-Prostatectomy Incontinence Treated with an Adjustable Transobturator Male System or Artificial Urinary Sphincter

Introduction

A prospective evaluation of outcomes in a series of patients with post-prostatectomy incontinence (PPI) treated with two different devices is presented.

Methods

Consecutive patients with PPI underwent interventions with an adjustable transobturator male system (ATOMS) or artificial urinary sphincter (AUS). Decisions were based on patient preference after physician counselling. Patient characteristics and operative and postoperative parameters including dryness, satisfaction, complications, revision and device durability were evaluated.

Results

One hundred twenty-nine patients were included: 102 (79.1%) received ATOMS and 27 (20.9%) AUS. Mean follow-up was 34.9 ± 15.9 months. No difference was observed between patient age (p = 0.56), ASA score (p = 0.13), Charlson index (p = 0.57) and radiation (p = 0.3). BMI was higher for AUS (27.1 vs. 29.7; p = 0.003) and also baseline incontinence severity (7.9% mild, 44.1% moderate and 48% severe for ATOMS vs. 11.1% moderate and 88.9% severe for AUS; p = 0.0007). Differential pad test was higher for AUS (− 470 vs. − 1000 ml; p < 0.0001) and so was ICIQ-SF (15.62 vs. 18.3; p < 0.001), but total dryness (76.5 vs. 66.7%; p = 0.33), social continence (90.2 vs. 85.2%; p = 0.49) and satisfaction (92.2 vs. 88.9%; p = 0.69) were equivalent. The postoperative complication rate was similar (22.6 vs. 29.6%; p = 0.4). The surgical revision rate was higher for AUS (6.9 vs. 22.2%; p = 0.029) and also the explant rate but did not reach statistical significance (4.9 vs. 14.8%; p = 0.09). Time to explant was shorter for AUS (log-rank p = 0.021). Regression analysis revealed radiation (p = 0.003) and incontinence severity (p = 0.029) predict total dryness, while complications (p < 0.005) and type of device (p = 0.039) independently predict surgical revision.

Conclusions

Both ATOMS and AUS are effective devices. Pad test change for AUS exceeds that of ATOMS. The revision rate is higher for AUS, and durability is superior for ATOMS. The satisfaction rate is equivalent. Larger series and longer follow-up are needed to compare both devices more appropriately. According to our experience, the AUS is not the only gold standard for PPI.

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.
