Abstract
We investigated patient satisfaction with the artificial urinary sphincter and established criteria for a successful outcome by inquiring about patient perceived satisfaction, continence achieved and comparison with the surgeon office records. During 9 years 65 patients with post-prostatectomy incontinence underwent placement of the AMS800 artificial urinary sphincter. Review of charts and a telephone questionnaire were conducted to determine patient perceived satisfaction. A total of 50 patients participated in the survey. Median followup was 23.4 months. Preoperative incontinence was severe. Of the patients 90% reported continuous leakage, and 70% wore an average of 6 diapers and 24% wore an average of 7.4 pads daily. The long-term complete continence rate was 20%. Of the patients with wetness 55% had leakage of a few drops daily and 22% had leakage of less than a teaspoon. Of all patients 50% had leakage daily, 24% had leakage 1 or more times a week and wore an average of 1.5 pads per day, and 6% reported changing clothes due to wetness. A total of 90% of the patients reported satisfaction with the artificial urinary sphincter and 96% stated that they would recommend or had recommended the artificial urinary sphincter to a friend. In retrospect, 92% of the patients would have the artificial urinary sphincter placed again, 90% of those undergoing revision reported no change in satisfaction and 14% reported improved sexual activity. Patient satisfaction with the artificial urinary sphincter for post-prostatectomy incontinence is uniformly high. Although postoperative continence was not 100%, relative improvement in continence was the most significant factor affecting patient perceived outcome. Using these parameters criteria for a successful outcome can be established, and patient concerns regarding the artificial urinary sphincter can be dispelled.
