title: The urethral sphincter: an update.
abstract: The urethral sphincter is a single mechanism capable of forming a watertight barrier to urinary leakage during bladder filling while changing its shape to serve as an effective conduit for bladder emptying during micturition. By abandoning traditional concepts of the two muscular sphincters, urologic clinicians are better able to assess and manage sphincter dysfunction causing SUI or bladder outlet obstruction.
