One hundred and seventy seven women with peri- and postmenopausal bleeding were subjected to vaginosonographic examination followed by thorough pathological examination of the uterine curetting samples. A mean endometrial thickness (double layer) of 13.2 +/- 3.6 mm and 8.2 +/- 4.8 mm were found in those with and without histological abnormalities, respectively. Endometrial thickness of less than 7 mm, however, was found to be predictive of normal endometrium (100% sensitivity, 46% specificity) and can, therefore, be used to separate those who require diagnostic curettage from those who do not. These findings suggest that this relatively simple, noninvasive procedure can be used as a screening test for patients with peri- or postmenopausal bleeding.
177例围绝经期和绝经后出血的女性接受了阴道超声检查，随后对子宫刮宫样本进行了全面的病理检查。有组织学异常和无组织学异常的女性，其平均子宫内膜厚度（双层）分别为13.2±3.6mm和8.2±4.8mm。然而，发现子宫内膜厚度小于7mm可预测子宫内膜正常（敏感性100%，特异性46%），因此可用于区分需要诊断性刮宫的患者和不需要的患者。这些发现表明，这种相对简单、无创的检查可作为围绝经期或绝经后出血患者的筛查试验。
