Artificial urinary sphincters for treating postprostatectomy incontinence: A contemporary experience from the UK.

Objectives: To report a real-time contemporary practice and outcome of artificial urinary sphincter (AUS) in patients with postradical prostatectomy urinary incontinence (PPI) in the UK.

Methods: A retrospective observational study of patients who underwent AUS implantation (AMS 800) from 2007 to 2013. Data were collected on patients' demographics, infection and erosion rate, mechanical failure, reoperation, and continence rates. The study strictly included patients with postradical PPI only. Minimum follow-up was 15 months.

Results: Eighty-four AUSs were implanted over a period of 6 years. Patients' age ranged between 51 and 78 (median 69, mean 69.25) years. Median follow-up was 37 months, mean 39 months, and range 15-92 months. Among the 83 follow-up patients, 38.5% (32/83) reported that they were completely dry with no pads; 42.2% (35/83) of patients were socially continent (using 1 pad/day) and 19.3% (16/83) using ≥2 pads/day. One patient was lost to follow-up. Reoperation rate was 13.25% (11/83), including nine mechanical failures (10.8%). Two implant infections (2.4%) required explantation, out of which one had erosion (1.2%). Bladder overactivity developed in 6% of patients. Of the 83, 15 (18%) had pelvic radiotherapy.

Conclusion: The implantation of AUS in patients with post-PPI has lower complications and reoperation rates than historical impression painted in the literature. This can be beneficial in counseling as well as during the education process of patients going through the decision process for prostate cancer treatment. Furthermore, these figures can add to our quest to increase the awareness of the success of anti-incontinence surgery among patients.
