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.
尿道括约肌是一种单一机制，在膀胱充盈时能够形成防水屏障以防止尿液泄漏，同时在排尿时改变其形状，作为膀胱排空的有效通道。通过摒弃两个肌肉括约肌的传统概念，泌尿外科临床医生能够更好地评估和处理导致压力性尿失禁或膀胱出口梗阻的括约肌功能障碍。
