Transvaginal sonography (TVS) was used to assess uterine contents in 100 consecutive subjects presenting with a diagnosis of spontaneous abortion. TVS assessments were correlated with findings at subsequent evacuation of retained products of conception (ERPC). There was a strong correlation between the weight of the surgical specimen at ERPC with both the sagittal (r = 0.76; p < 0.05) and transverse (r = 0.73; p < 0.05) plane area measurements of the uterine cavity. Combining the 2 sonographic measurements increased the correlation to r = 0.81 (p < 0.05). Fifteen of 25 subjects who had been categorised to have an 'empty' uterus had less than 5 g of tissue removed and the other 10 subjects less than 10 g of tissue. In 20 of these 25 cases, the surgeon described the amount of curettings as 'small or non-significant'. TVS can accurately identify those women who do not have a significant amount of residual uterine tissue following spontaneous abortion.
经阴道超声检查（TVS）用于评估100例连续诊断为自然流产的受试者的子宫内容物。TVS评估结果与后续清宫术（ERPC）时的发现相关。ERPC时手术标本的重量与子宫腔矢状面（r = 0.76；p < 0.05）和横断面（r = 0.73；p < 0.05）平面面积测量值之间存在强相关性。将这两种超声测量方法结合起来，相关性提高到r = 0.81（p < 0.05）。在25名被归类为子宫“空虚”的受试者中，有15名清除的组织少于5克，另外10名清除的组织少于10克。在这25例中的20例中，外科医生描述刮出物的量为“少或无意义”。TVS能够准确识别自然流产后子宫内没有大量残留组织的女性。
