Biophysical properties of the anterior vaginal wall as well as the rectus fascia were evaluated in vivo by penetrating the Stamey needle into these tissues of 26 female patients with stress incontinence in comparison with those of 21 continent subjects. The results demonstrated that shear strength of the anterior vaginal wall was lower in incontinent patients than in continent subjects (P < 0.01). Shear strength of the rectus fascia in the patients, which was not supposed to be related to urinary incontinence and should have had the same strength as the control subjects, was also found to be lower than the control (P < 0.01). Shear strength of the vaginal wall was not correlated with age irrespective of their continence status (P > 0.05). Based on our findings it is concluded that some women suffering from stress incontinence may have a hereditary disorder of biophysical properties of the tissues.
通过将斯坦梅针插入26例压力性尿失禁女性患者以及21例控尿正常受试者的这些组织中，对阴道前壁以及腹直肌筋膜的生物物理特性进行了体内评估。结果表明，尿失禁患者阴道前壁的抗剪强度低于控尿正常受试者（P < 0.01）。患者腹直肌筋膜的抗剪强度也低于对照组（P < 0.01），而腹直肌筋膜的抗剪强度本应与尿失禁无关，且应与对照组强度相同。无论其控尿状态如何，阴道壁的抗剪强度均与年龄无关（P > 0.05）。基于我们的研究结果得出结论，一些患有压力性尿失禁的女性可能存在组织生物物理特性的遗传性疾病。
