OBJECTIVES: To assess our institutional outcomes after primary artificial urinary sphincter (AUS) failures. METHODS: From 1985 to 2010, a total of 149 patients underwent 318 primary and additional AUS procedures. We classified additional procedures as revisions, replacements, or explantations. RESULTS: At a median of 52 months (range, 6-250 months), 53% of patients had required at least 1 additional procedure beyond their initial implantation. These included 106 (63%) revisions, 42 (24.9%) explantations, and 21 (12.4%) replacements. The most common revision was reservoir upsizing (37/106). Reasons for first revision included recurrent incontinence (56.7%), mechanical malfunction (22%), and infection or erosion (18.6%). Explantations were performed primarily for infection and erosion (64.3%). Median time to first revision was 20.1 months (range, 0.1-173 months) after implantation, with a median of 9.5 months (range, 1-102 months) between revisions. Explantation occurred at a median of 22 months (range, 1-221 months) after implant, and subsequent replacement at a median of 33.6 months (range, 2-138 months). At 5 years, 28/83 (33.7%) patients had undergone no additional procedures. Patients with previous radiation were more likely to experience infection (P = .03; OR 3.99; 95% CI 1.03-15.42). Patients with previous myocardial infarction were more likely to experience erosion (P = .04; OR 2.29; 95% CI 1.05-5.02), and obese patients were more likely to experience mechanical malfunction (P = .04; OR 2.62; 95% CI 1.07-6.4). CONCLUSIONS: More than half of patients with an AUS will require additional procedures, most likely revision. Radiation, previous myocardial infarction, and obesity are linked to complications. Median time to first revision or explantation is slightly less than 2 years, indicating that long-term follow-up is required after initial implantation.
