Artificial Urinary Sphincter Cuff Size Predicts Outcome in Male Patients Treated for Stress Incontinence: Results of a Large Central European Multicenter Cohort Study

Purpose The aim was to study the correlation between cuff size and outcome after implantation of an AMS 800 artificial urinary sphincter. Methods A total of 473 male patients with an AMS 800 sphincter implanted between 2012 and 2014 were analyzed in a retrospective multicenter cohort study performed as part of the Central European Debates on Male Incontinence (DOMINO) Project. Results Single cuffs were implanted in 54.5% and double cuffs in 45.5% of the patients. The cuffs used had a median circumference of 4.5 cm. Within a median follow of 18 months, urethral erosion occurred in 12.8% of the cases and was associated significantly more often with small cuff sizes (P<0.001). Multivariate ana…
