Artificial urinary sphincter – new devices in male urinary incontinence treatment

The incidence of male stress urinary incontinence (UI) ranges from 4.81 to 32.17% and usually increases with age. UI can be a consequence of surgical treatment of benign prostate hyperplasia (BPH) and/or prostate cancer (PCa). The American Medical System type 800 (AMS800) has been the most common and, until recently, the only artificial urinary sphincter (AUS) available for UI surgical treatment. Due to differences in UI grades and a considerable number of complications as well as costs associated with AUS implantation, several new devices for UI treatment have been introduced in the recent years. These devices offer novel technological solutions, which in theory should provide at least similar functional outcomes and lower complications associated with the classical AMS sphincter. The study provides a review of new devices for male stress UI treatment.
