199 Is Removal of the Pressure Regulating Balloon Necessary after Artificial Urinary Sphincter Cuff Erosion?

Abstract

To characterize the fate of the retained pressure regulating balloons (PRB) after artificial urinary sphincter (AUS) cuff erosion. Between 2007-2016 at our institution, there were 40 total AUS cuff erosions. Twenty-four (60%) presented without evidence of device infection and underwent explant of cuff and pump without removal of the PRB. Both Space of Retzius (SoR) and high submuscular (HSM) balloon locations were included. Presenting clinical features and retained balloon-related outcomes are reported. Of the 24 AUS cuff erosions with retained balloons, 6 (25%) men subsequently required PRB removal for infection during a median follow-up of 36 months (IQR 29-53). The most common presenting clinical symptoms with retained PRB infection were pain and erythema near the site of the PRB (83%). No patient developed sepsis-related complications. Median time to balloon infection after AUS erosion surgery was 4 months (IQR 4-16). Location of the PRB in this subcohort included 2 SoR and 4 HSM placements. Median operative time for balloon removal in the SoR was 3.5 times greater than for HSM PRBs (133 minutes vs. 38 minutes).
