Longitudinal changes in patient-reported outcomes after artificial urinary sphincter implantation

Longitudinal deterioration in lower urinary tract symptoms after artificial urinary sphincter implantation in patients with a history of pelvic radiation therapy

OBJECTIVES

To evaluate longitudinal changes in lower urinary tract symptoms (LUTS) after artificial urinary sphincter (AUS) implantation in patients undergoing radiation therapy (RT) in comparison to those in non-irradiated patients.

METHODS

This retrospective study included 20 and 51 patients with and without a history of pelvic RT (RT and non-RT group, respectively) who were treated with primary AUS implantation for post-radical prostatectomy incontinence between 2010 and 2020. Longitudinal changes in the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), the International Prostate Symptom Score (IPSS), and the Overactive Bladder Symptom Score (OABSS) were calculated with a linear mixed model.

RESULTS

In the RT and non-RT group, 18 (90%) and 48 (94%) patients achieved social continence, defined as daily pad use ≤1 at 1 month after activation of AUS, respectively (p = .555). During the mean follow-up of 38 months, ICIQ-SF, IPSS, and OABSS significantly improved after AUS implantation in both the RT and non-RT groups. In the RT group, ICIQ-SF, IPSS, and OABSS subsequently deteriorated with a slope of 0.62/year (p = .010), 0.55/year (p = .025), and 0.30/year (p = .007), respectively. In the non-RT group, no significant longitudinal changes in subsequent IPSS and OABSS were observed, although ICIQ-SF significantly deteriorated (0.43/year, p = .006). Comparing between the groups, the slopes of IPSS and OABSS were significantly greater in the RT group than in the non-RT group (p < .001, and .015, respectively).

CONCLUSIONS

Longitudinal deterioration in LUTS that improved immediately after AUS implantation was observed in patients with a history of pelvic RT, but not in patients without a history of pelvic RT.

Effectiveness of artificial urinary sphincter to treat stress incontinence after prostatectomy: A meta-analysis and systematic review

BACKGROUND

Artificial Urinary Sphincter (AUS) has always been considered the gold standard for surgical treatment of male non-neurogenic Stress Urinary Incontinence (SUI). The purpose of this meta-analysis was to evaluate AUS's effectiveness in treating male SUI, as described in the literature.

METHODS

Two independent reviewers used PubMed, EMBASE, Web of Science, CNKI, WanFang Data, and VIP databases, to find the efficacy of artificial urethral sphincter in treating SUI after male prostate surgery. We excluded studies on female urinary incontinence. The main purpose of this study was to evaluate the clinical efficacy based on the degree of dry rate after AUS AMS 800™: postoperative complete dry was defined as no pad use per day. Postoperative social dry was defined as 0-1 pad per day. The secondary goal was to analyze the use of AUS AMS 800™ to improve SUI and to calculate the degree of influence by analyzing the number of pads and postoperative quality of life. And methodologic quality of the overall body of evidence was evaluated using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) guidelines.

RESULTS

The data in this paper are mostly based on prospective or retrospective cohort studies without control groups. Fortunately, most studies have the same criteria to assess effectiveness. The pooled data of 1271 patients from 19 studies (6 prospective cohort studies, 12 retrospective cohort studies, and 1 randomized controlled trial) showed that: the number of pads used (pads/ day) after AUS was significantly reduced by about 4 (P < 0.001) and the quality of life was improved (P < 0.001).In addition, data analysis showed a high degree of heterogeneity between studies. According to the severity of baseline SUI, subgroup analysis was performed on the postoperative dry rate and social dry rate. Although heterogeneity was reduced, I2 is still above 50%, considering that heterogeneity may not be related to the severity of SUI. The random effect model was used for data analysis: the dry rate was about 52% (P < 0.001), and the social dry rate was about 82% (P < 0.001). The evidence level of GRADE of dry rate is very low, the evidence level of social dry rate and Pads use (pads/day) is Moderate, and the evidence level of Quality of life is low.

CONCLUSION

Although the evidence in this paper is based on descriptive studies and limited follow-up, the results show that AUS is effective in treating urinary incontinence and can improve patients' quality of life.

Understanding the Health Characteristics and Treatment Choices of Older Men with Stress Urinary Incontinence

OBJECTIVE

To describe the health characteristics and current treatment choices of male stress urinary incontinence (mSUI) patients to inform patient-centered decision-making.

METHODS

We identified a cohort of mSUI patients aged ≥65 at UCSF and San Francisco VA. Using retrospective chart review and telephone interviews, we ascertained demographics, incontinence characteristics, Charlson Comorbidity Index (score ≥ 4 indicates significant morbidity), frailty with Timed Up and Go (TUG) test, functional dependence with activities of daily living (ADL), calculated life expectancy, and assessed mental health and quality of life (QOL). Bivariate analysis evaluated associations between subject characteristics and ultimate treatment type (conservative vs surgery; sling vs sphincter). Logistic multivariable models evaluating treatment choice were also constructed.

RESULTS

The 130 participants had a mean age of 75 and a mean incontinence score of 14.2 representing moderately bothersome incontinence. Nearly 80% had significant morbidity, three-quarters had >50% 10-year mortality risk, 10% needed help with 1 + ADL and 22% had a TUG >10 seconds indicating frailty. The mean physical and mental QOL scores were similar to the general population. Anxiety and depression were reported by 3.9% and 10%. In univariate and multivariable analysis, only incontinence characteristics were associated with conservative vs surgical treatment choice (P < .01).

CONCLUSION

Multi-morbidity, functional dependence, frailty, and limited life expectancy are common among older men with mSUI, yet current treatment choices appear to be driven by incontinence characteristics. As such, mSUI surgery should be considered among men across the spectrum of health and life expectancy.

[REPARATIVE SURGERY OF PRESSURE-REGULATING BALLOON HERNIA AFTER ARTIFICIAL URINARY SPHINCTER REPLACEMENT: A CASE REPORT]

A 74-year-old male with post-prostatectomy incontinence underwent artificial urinary sphincter replacement due to device malfunction. Three months after the replacement surgery, he presented for a consultation due to a bulging area in his lower abdomen. Computed tomography revealed a hernia of the pressure-regulating balloon (PRB), while the device was working well. In the reparative surgery, reopening the lower abdominal incision, the PRB was carefully restored to its previous position after creating a sufficient submuscular space. As the rectus abdominis fascia showed an adequate strength, the fascia was tightly sutured without using a prosthetic mesh. Thereafter, the patient has been free from incontinence for two and a half years without hernia recurrence. Given the mechanical nature of the device, replacement surgery is sometimes required over time. Tissue fragility due to repetitive surgeries and increasing ambient pressure due to space reduction derived from the PRB deflation could cause PRB hernia. Such cases can be treated under careful manipulation without damaging the device. Considering the future potential need for repeated surgery, it would be preferable not to use prosthetic mesh, as it can cause dense adhesion.
