Abstract
Introduction
Stress urinary incontinence (SUI) affects between 2.5% and 40% of patients after radical prostatectomy. Although the implantation of an artificial urinary sphincter (AUS) offers continence rates of 70-80%, its failure rate reaches 25% in some series. This single-center retrospective study analyzed the survival of AUS and the factors associated with its failure.
Materials and methods
A total of 145 patients treated with the AMS 800® device (Boston Scientific) between 2010 and 2023 were included. Kaplan-Meier analysis and the Cox proportional hazards model were used to evaluate device survival and identify predictive factors for failure.
Results
The mean age was 68.6 years; 28% of patients were smokers, 43.7% had diabetes, and 26.2% had undergone prior radiation therapy. Radical prostatectomy was the main cause of SUI (86.9%). In the majority of cases (91.5%), the artificial urinary sphincter was implanted around the bulbar urethra. During follow-up, 25.5% of patients required revision surgery. The probability of functional sphincter survival was 89% at 1 year, 78% at 2 years, 64% at 5 years, and 51% at 10 years. On multivariate analysis, prior radiation therapy (HR: 2.06; P=.029) and diabetes (HR: 2.24; P=.04]) were associated with poorer device survival.
Conclusions
The AUS is an effective and safe treatment for severe SUI, although radiotherapy and diabetes may adversely affect its durability.
