The Role of the Artificial Urinary Sphincter: Current Status and Future Innovations

Abstract  Purpose of ReviewThe artificial urinary sphincter has remained the gold standard treatment for male stress urinary incontinence since its first iteration by American Medical Systems in 1972. It is the treatment of choice for moderate to severe incontinence, as well as post-radiation incontinence. Understanding the anatomy and physiology of male stress incontinence, as well as the indications and outcomes for artificial urinary sphincter implantation, remains integral to a discussion of sphincter technology.Recent FindingsWhile the basic artificial urinary sphincter mechanism has not changed in decades, burgeoning innovations in recent years herald a new generation of sphincter technology. In addition to artificial sphincter innovation, the future of male stress urinary incontinence treatment will include the integration of regenerative treatments for patients ’ native sphincters. As opposed to our current treatment options, which manage the symptoms, the aim of cell-based therapies is to truly reverse the primary pathophysiology of intrinsic sphincter deficiency thereby treating the cause of stress urinary incontinence. For some, regenerative medicine may even make artificial urinary sphincters obsolete.SummarySavvy technologic enhancements will inevitably deliver a positive impact on men with stress urinary incontinence and continue to substantially improve quality of life for decades to come.
