Workup of residual incontinence after artificial urinary sphincter placement

Abstract

Artificial urinary sphincter (AUS) is the gold standard for treatment of male stress urinary incontinence. Despite high success rates, some men continue to experience incontinence after AUS placement. The workup of residual incontinence is based on its potential etiologies, including improper use, underlying physiologic bladder dysfunction, mechanical failure such as device malfunction or system leak, technical failure such as poor sizing of the cuff or balloon, tissue atrophy, or cuff erosion. Here, we offer a framework to evaluate these potential causes.
