Continence and quality of life assessment after artificial urinary sphincter implantation

Sphincter-related incontinence after radical prostatectomy, benign prostatectomy or due to neurogenic disease has a considerable negative impact on quality of life. Artificial urinary sphincter implantation is a mainstay therapeutic option for these patients.

To assess patient satisfaction, subjective long-term continence and complications after AMS 800 artificial urinary sphincter implantation.

The medical records of 34 patients who underwent artificial urinary sphincter implantation for radical prostatectomy (n = 23), simple prostatectomy (n = 9) or neurogenic disease (n = 2) between 1995 and 2003 were studied retrospectively. Median follow-up was 49 months (range 3-102 months). Records were analyzed for urinary sphincter survival and complications. Quality of life and continence assessment was done by mailing an impact questionnaire.

In 4 of the 34 patients (11.7%) the device was removed due to infection. One of the four had surgical revision elsewhere, and the other three were not interested in re-implantation of the device. Two patients (5.9%) underwent revisions due to mechanical failure. One patient died and three patients were not located. Twenty-seven out of a possible 30 patients (88%) completed the questionnaire; 22 (85%) achieved social continence (0-2 pads daily), and one patient had subjective difficulty activating the device. Subjective improvement and patient satisfaction was rated as 4.22 and 4.11, respectively (scale 0 to 5).

Artificial urinary sphincter implantation is an efficacious option for sphincter-related incontinence. This study documents the positive impact of artificial urinary sphincter implantation on quality of life with acceptable complications; these results are comparable to other published studies.
