The physiology of continence was studied in 33 continent and 62 incontinent females, respectively, under morphological aspects. Only 60 percent of the urethral length were found to ensure full close patency. This region is represented by a circular musculatory sphincter system. It was found that stress situations may cause changes in the sphincteric function along with a rise in the abdominal pressure. Urethral closure patency was found to be disturbed even at a resting state. The changes which were observed in the resting continence have been manifested themselves as a shortening of the closing proximal urethra "in itself" and a corresponding shortening of the absolute anatomical urethral length by the same proportion. The anatomical urethral length in females is therefore of clinical significance in the diagnostical screening for urinary incontinence.
分别从形态学角度对33名控尿女性和62名尿失禁女性的控尿生理进行了研究。发现只有60%的尿道长度能确保完全闭合通畅。该区域由一个环形肌肉括约肌系统构成。研究发现，应激情况可能会导致括约肌功能发生变化，同时腹压升高。即使在静息状态下，尿道闭合通畅也会受到干扰。在静息控尿过程中观察到的变化表现为近端尿道“自身”闭合长度缩短，以及绝对解剖学尿道长度相应缩短相同比例。因此，女性的解剖学尿道长度在尿失禁的诊断筛查中具有临床意义。
