PURPOSE: The artificial urinary sphincter continues to be one of the most effective and commonly used surgical treatments for severe urinary incontinence. The long-term durability and functional outcome remains unclear. This study sought to report the artificial urinary sphincter complication rates, associated risk factors with complications, and long-term quality of life and durability. MATERIALS AND METHODS: This single institution study reports the outcomes of 124 consecutive index cases of artificial urinary sphincter from 1996 to 2006 for complications (infection, erosion, and mechanical failure). Bivariate statistics and multivariable logistic models were used to identify patient and artificial urinary sphincter characteristics associated with complications. Functional outcomes and long-term durability were assessed using a cross sectional analysis of a validated health related quality of life survey and a product limit estimates, respectively. RESULTS: Among the 124 male patients median followup was 6.8 years. The overall complication rate for patients undergoing an artificial urinary sphincter was 37.0%, with mechanical failure the most common cause (29), followed by erosion (10) and then infection (7). Significant differences between complications and specific patient and artificial urinary sphincter characteristics risk factors were not found. Functional outcomes appeared stable with similar mild-moderate urinary incontinence severity and 0 to 1 daily pad use at intervals of 0 to 4 years, 4 to 8 years and more than 8 years. Long-term durability was notable with 36% having complications (requiring surgical revision or removal) within 10 years and most events occurring within the first 48 months. CONCLUSIONS: Long-term durability and functional outcomes are achievable for the AMS 800, but there are appreciable complication rates for erosion, mechanical failure and infection in the first 48 months from implantation.
