325 Does Urethral Repair Prevent Complications from AUS Cuff Erosions? A Decade of Experience

Abstract

Artificial Urinary Sphincter (AUS) cuff erosion occurs in 8.5% of cases and requires removal of the device.1 Management options include urethral catheter placement alone or in situ urethroplasty (ISU) at the time of explant. It has previously been reported that stricture rates are higher in patients managed with catheter placement alone versus ISU (85% v 35% respectively)2. To determine the stricture rate in patients who undergo ISU after AUS cuff erosion in a large tertiary referral practice. We performed a retrospective cohort study of patients who underwent AUS removal by a single surgeon, secondary to erosion, from January 2006 to June 2019. We identified those who were managed with ISU at the time of explant. The electronic medical records were reviewed for patient demographics, operative details, and development of stricture at follow up. The degree of urethral erosion was defined by percent of urethral circumferential defect noted intra-operatively or on pre-operative cystoscopy. Urethral patency was studied at follow up with voiding cystourethrogram, retrograde urethrogram or cystoscopy.
