Twenty-eight women with postmenopausal bleeding were retrospectively studied to assess the accuracy of transvaginal sonography (TVS) and hysteroscopy for diagnosing endometrial pathology. TVS was performed in all patients. Considering a cutoff value of < or = 5 mm as normal, TVS showed normal findings in 14 patients (50%) and suggested endometrial abnormalities in other 14 (50%). Hysteroscopy could be performed in 24 patients (85.7%). In 17 (70.2%) cases no abnormality was found; an endometrial polyp was suspected in 6 (25%) and endometrial hyperplasia in 1 (4.8%) patient. All patients underwent endometrial biopsy or dilatation and curettage for histopathologic study. Sensitivity, specificity, and positive and negative predictive values for TVS and hysteroscopy were 100, 60.8, 35.7, and 100% and 100, 89.4, 71.4, and 100%, respectively. In our experience, both methods were highly sensitive, but hysteroscopy was more specific than TVS.
对28例绝经后出血的女性进行回顾性研究，以评估经阴道超声检查（TVS）和宫腔镜检查诊断子宫内膜病变的准确性。所有患者均接受了TVS检查。以≤5mm为正常临界值，TVS检查显示14例患者（50%）结果正常，另外14例（50%）提示存在子宫内膜异常。24例患者（85.7%）接受了宫腔镜检查。其中17例（70.2%）未发现异常；6例（25%）怀疑有子宫内膜息肉，1例（4.8%）怀疑有子宫内膜增生。所有患者均接受了子宫内膜活检或刮宫术以进行组织病理学研究。TVS和宫腔镜检查的敏感性、特异性、阳性预测值和阴性预测值分别为100%、60.8%、35.7%、100%和100%、89.4%、71.4%、100%。根据我们的经验，两种方法均具有较高的敏感性，但宫腔镜检查比TVS更具特异性。
