OBJECTIVE: To evaluate long-term functional outcomes of artificial urinary sphincters (AUSs) and to determine how many men required explantation because of stress urinary incontinence (SUI) caused by sphincter deficiency after prostate surgery.
MATERIAL AND METHODS: Men who had undergone placement of an AMS 800® between 1984 and 1992 to relieve SUI caused by sphincter deficiency after prostate surgery were included. Continence, defined as no need for pads, was assessed at the end of the follow up. Kaplan-Meier survival curves estimated the survival rate of the device without needing explantation or revision.
RESULTS: Fifty-seven consecutive patients were included (median age 69 years; IQR: 64-72). Median duration of follow-up was 15 years (IQR: 8.25-19.75). At the end of follow-up, 25 patients (43.8%) still had their primary AUS. Explantation of an AUS was done in nine men because of erosion (n=7) and infection (n=2). Survival rates, without AUS explantation, were 87, 87, 80, and 80% at 5, 10, 15, and 20 years, respectively. Survival rates, without AUS revision, were 59, 28, 15, and 5% at 5, 10, 15, and 20 years, respectively. At the end of the follow-up, in intention-to-treat analysis, 77.2% of patients were continent.
CONCLUSION: In the long term (>10 years) the AMS 800® can offer a high rate of continence to men suffering from SUI caused by sphincter deficiency, with a tolerable rate of explantation and revision.
