Abstract

Objective: To evaluate characteristics of artificial urinary sphincter (AUS) mechanical failures and compare outcomes based on the use of either suture−tied connections or Quick−Connects® (QC) for single-component revisions.

Material and methods: A total of 46 patients underwent single-component AUS revisions following primary AUS placement from January 1983 to January 2011 at our institute. Prior to 1996 all revision cases were performed with suture−tie connections and after that time we used QC for revisions. Device success was evaluated for a potential association with revision surgery including the type of connector used.

Results: Forty-six patients underwent single-component revision surgery for primary device malfunction. In these cases, the tubing connections were performed using suture−tie connectors in 34 (74%), and QC in 12 (26%) cases. The median age was 68.8 years for suture-tie vs 70.6 years for QC (p=0.52). The median follow-up period after revision surgery was 24 months (IQR 7.2, 55.2). There was no statistically significant difference in 5-year device survival rates between suture−tie and QC (36% vs. 61%; p=0.85) techniques. There were no cases of device infection or repeat mechanical failure at the connector among cases of revision performed using QC, as compared to five device infections and four repeat mechanical failures among the suture-tie cohort.

Conclusion: The use of QC for single-component AUS revision for mechanical failures appears to be safe, efficient and reliable. There is not enough evidence supporting the presence of an association between connector type with the risk of overall device failure.
