Surgical strategies in artificial urinary sphincter revision surgery: troubleshooting the complications.

Post-prostatectomy urinary incontinence (PPUI) is an important issue in the urological practice and imposes a negative effect on quality of life (QoL). Despite recent technological advances, PPUI remains a common complication and the artificial urinary sphincter (AUS) is regarded as the most effective long-term surgical treatment for moderate-to-severe stress urinary incontinence. Success rates for AUS as defined by a continence status of zero to one pad per day range from 59% to 90%. One potential downside of the AUS is the need for periodic revisions in a number of patients. Revision and explantation rates due to mechanical failure, urethral atrophy, infection and erosion vary considerably among studies with reports of 8-45% and 7-17%, respectively. These complications can be classified into different categories, including recurrent or refractory incontinence, erosion and/or infection, and other complications. This review article aims to describe the main AUS-related complications and their management strategies. Diagnostic work-up strategies are explored to facilitate timely identification and management of these complications. Additionally, emerging technologies and future directions in AUS development are discussed, highlighting potential advancements to mitigate complications and enhance device performance. This review consolidates current knowledge and provides insights for clinicians to manage the complexities associated with AUS therapy effectively.
