Radiotherapy is associated with reduced continence outcomes following implantation of the artificial urinary sphincter in men with post-radical prostatectomy incontinence.

ABSTRACT: The objective of this study is to present the outcomes of men undergoing implantation of artificial urinary sphincter, after treatment for prostate cancer and also to determine the effect of radiotherapy on continence outcomes after artificial urinary sphincter (AUS) implantation.A prospectively acquired database of all 184 patients having AUS insertion between 2002 and 2012 was reviewed, and demographic data, mode of prostate cancer treatment(s) before implantation, and outcome in terms of complete continence (pad free, leak free) were assessed. Statistical analysis was performed by Chi-squared and Fisher's exact tests.A total of 58 (32%) men had bulbar AUS for urodynamically proven stress urinary incontinence consequent to treatment for prostate cancer in this period. Median follow-up post-AUS activation was 19 months (1-119). Forty-eight (83%) men had primary AUS insertion. Twenty-one (36%) men had radiotherapy as part of or as their sole treatment. Success rates were significantly higher in nonirradiated men having primary sphincter (89%) than in irradiated men (56%). Success rates were worse for men having revision AUS (40%), especially in irradiated men (33%).Radiotherapy as a treatment for prostate cancer was associated with significantly lower complete continence rates following AUS implantation.

Project description:IntroductionA prospective evaluation of outcomes in a series of patients with post-prostatectomy incontinence (PPI) treated with two different devices is presented.MethodsConsecutive 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.ResultsOne 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.ConclusionsBoth 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.

Project description:BackgroundArousal incontinence (AI) occurs during physical or psychological sexual stimulation in men and has been described after radical prostatectomy (RP).AimThe goals of this study are to describe the characteristics of men experiencing AI, outline the nature of their symptoms, and assess for predictors of this condition.MethodsA survey with questions on AI, stress urinary incontinence (SUI), the International Index of Erectile Function and International Prostate Symptom Score were sent out to men who had undergone an RP within the past 24 months at a single institution. The data were deidentified and analyzed using descriptive statistics. Comparisons between men with and without AI were made using t-tests and χ2 and Fisher exact tests. Logistic regression in univariable and multivariable analyses were used to define predictors of AI.Main outcome measuresThe outcomes of this study included prevalence of AI, symptom severity and timing, patient and patient-perceived partner bother, management strategies used by the patients, and concurrent SUI.Results226 (32%) men completed the survey. Of these men, almost half (49%) experienced AI at some point during their recovery. Improvement over time was endorsed by 62% of men. 57% of men reported AI in less than half of the sexual encounters, with the amount of urine leakage being equivalent to a tablespoon or less in 88% of men. On univariate analysis, increasing degree of SUI, as measured by pads per day, was associated with AI (P = .01). A lower International Prostate Symptom Score was also associated (P = .05). On multivariate analysis, the absence of hypertension and pads per day were associated with AI (P = .01 for both).Clinical implicationsAI occurred in almost half of the respondents in our series. Thus, AI should be discussed with patients before surgery to allow for realistic expectations.Strengths & limitationsStrengths of this study include the largest patient population analyzed to date regarding AI and that it is the only one to address timing and patient experiences with the use of validated instruments for erectile and urinary function. Limitations include single-center data, non-validated AI patient-reported outcomes, and poor survey response rate.ConclusionBased on the available data, AI is reported by almost half of men after RP and is associated with SUI.

Project description:PurposeOur primary aim was to present a combined technique to protect the anatomic integrity of distal urethral sphincter complex (DUSC) during minimally invasive radical prostatectomy (RP) and discuss its impact on urinary continence (UC) recovery. The second aim was to define the learning curve of the combined technique.MethodsWe conducted a non-randomized retrospective study. There were 314 consecutive patients who received RP by the same urologist surgeon with more than 2,000 prior cases in Shanghai Ruijin Hospital between March 2017 and April 2020. Included in this study were 263 patients with clinical T1-T2 stage. We modified a combined RP (Comb-RP) technique including endopelvic fascia no-incising technique, dorsal venous complex (DVC) no-ligation technique, intrafascial dissection technique, and anterior reconstruction technique so as to preserve the anatomic integrity of DUSC. The patients were assigned to two groups: a Comb-RP group and a conventional RP (Conv-RP) group. Continence rates were assessed every 3 months after removal of the catheter. UC was defined as 0 pad per day. Peri-operative variables of the patient including operation time, estimated blood lost (EBL), positive surgical margin (PSM), and postoperative complications were also collected. Scatter-graphs of learning curves were drawn using locally weighted scatterplot smoothing (LOWESS).ResultsRP was accomplished smoothly in all 263 cases. The pad-free UC rates in Conv-RP group and Comb-RP group were 17.3 vs. 27.8% (P = 0.048) at the removal of the catheter, 35.8 vs. 50.0% (P = 0.027) at 1 month, 60.5 vs. 76.1% (P = 0.012) at 3 months, 87.7 vs. 96.5% (P = 0.022) at 6 months, and 94.7 vs. 97.7% (P = 0.343) at 12 months. Kaplan-Meier analysis showed significantly higher and faster continence recovery in the Comb-RP group (mean 4.9 vs. 2.6 months, Log Rank P = 0.001). There was no significant difference in PSM rate between the Comb-RP and Conv-RP group (31.1 vs. 31.2%, P =0.986). The learning curves of peri-operative variables, oncological and functional outcomes achieved the lowest point or plateau at the 20th-60th cases.ConclusionsThe anatomic integrity and intact pelvic floor interplay of DUSC is important for its function. Our combined technique was a safe and feasible technique for improving early UC in RP with no significantly increased PSM rate and no significant difference in long-term UC.
