本研究的目的是验证一种使用二维超声测量阴道壁厚度 (VWT) 的技术。女性由两名独立操作员和同一名操作员在膀胱颈、膀胱顶端、前穹窿、肛门直肠交界处、直肠和后穹窿水平两次单独就诊进行扫描。对新鲜的女性尸体进行扫描，并将阴道的超声厚度与组织学厚度进行比较。Bland Altman 分析显示，操作员之间以及同一操作员访问之间的平均差异较低。 95% 置信区间占平均阴道壁厚度的百分比介于 2.8% 和 7.4% 之间。超声和组织学阴道壁厚度之间的百分比差异很小。超声阴道壁厚度显示出良好的术内和术间可靠性，以及与组织学测量的一致性。这是一种有效的技术。
The aim of this study was to validate a technique to measure the vaginal wall thickness (VWT) using two-dimensional ultrasound.Women were scanned by two independent operators and by the same operator at two separate visits at the level of the bladder neck, the apex of the bladder, the anterior fornix, the anorectal junction, rectum and posterior fornix. Fresh female cadavers were scanned and ultrasound thickness of the vagina was compared to histological thickness.Bland Altman analysis revealed a low mean difference between operators and between visits by the same operator. The 95% confidence intervals as a percentage of the mean vaginal wall thickness ranged between 2.8% and 7.4%. There was a low percentage difference between ultrasound and histological vaginal wall thickness.Ultrasound vaginal wall thickness demonstrated good intra- and interoperator reliability, as well as consistency with histological measurement. It is a valid technique.
