Abstract
Continence and micturition involve urethral closure. Especially, insufficient strength of the pelvic floor muscles including the urethral sphincter muscles causes urinary incontinence (UI). Thus, it is most important to understand the main mechanism causing UI and the relationship of UI with the urethral sphincter. Functionally and anatomically, the urethral sphincter is made up of the internal and the external sphincter. We highlight the basic and clinical anatomy of the internal and the external sphincter and their clinical meaning. Understanding these relationships may provide a novel view in identifying the main mechanism causing UI and surgical techniques for UI.
摘要
控尿和排尿涉及尿道闭合。特别是，包括尿道括约肌在内的盆底肌肉力量不足会导致尿失禁（UI）。因此，了解导致 UI 的主要机制以及 UI 与尿道括约肌的关系非常重要。从功能和解剖学上看，尿道括约肌由内括约肌和外括约肌组成。我们强调内括约肌和外括约肌的基础和临床解剖及其临床意义。了解这些关系可能为确定导致 UI 的主要机制以及 UI 的手术技术提供新的视角。
