Evolution of implanted devices for urinary incontinence1

Abstract

Prosthetic devices have been developed for management of severe urinary incontinence, which is usually not well treated with operations using host tissues. Early prostheses consisted of passive, compressive devices for the male bulbous urethra. In 1972, Scott and associates developed a hydraulic, artificial urinary sphincter (AS 721) which was implantable both in the male and female patient. Since then, design modifications have resulted in the AS 761, AS 742, AS 791, AS 792, and AS 800 models. The evolution of these devices is reviewed
