[摘要] 目的 探讨经阴道超声(TVS)对阴道不规则出血妇女内膜疾病的检查及早期诊断子宫内膜癌的应用价值。方法 35例子宫内膜癌患者经TVS测量两层子宫内膜厚度的最大值，观察低回声晕完整程度以确定是否有内膜癌的肌层浸润程度，先测量肌层厚度，再测量宫腔线至浸润灶外侧的距离，根据浸润深浅分为：无肌层浸润、浅肌层浸润(浸润深度<原肌层的50%)、深肌层浸润(浸润深度>原肌层的50%)。结果 早期病变TVS表现为内膜线紊乱1例，宫腔内线状不均匀强回声2例，宫腔内不均匀强回声伴宫腔内积液2例，内膜厚度(19±12)mm。结论 TVS是筛选子宫内膜病变的有效手段，结合病理诊刮可筛查出子宫内膜癌的高危病例以及准确判断内膜癌肌层浸润程度，对内膜癌的分期及疗效观察有重要的应用价值。
