摘　　要：目的:分析不同超声方法对妊娠中期不同形态宫颈长度的测量价值。方法:选择2017年1月-2018年9月本院具有早产高危因素行超声检查产妇352例,按照宫颈形态分为宫颈直线组及宫颈非直线组,两组分别应用经会阴直线法、轨迹法和经阴道直线法和轨迹法测量宫颈长度,比较不同方法测量值及对早产的预测效能。结果:宫颈直线组不同测量方法的测量值无差异(P>0.05),宫颈非直线组经会阴及经阴道轨迹法测量值均大于经会阴及经阴道直线法(P<0.001);宫颈直线组不同测量方法测量值<2.5孕妇发生早产率无差异(P>0.05),宫颈非直线组轨迹法测量值<2.5孕妇发生早产率大于直线法(P<0.05)。宫颈直线组不同测量方法对早产的预测敏感性、特异性、阳性预测值及阴性预测值均无差异(P>0.05),宫颈非直线组轨迹法对早产的预测敏感性、特异性、阳性预测值及阴性预测值均大于直线法(P<0.05)。结论:宫颈呈直线状体时各方法测量值及对早产的预测价值一致性较好,呈非直线状体时轨迹法测量较直线法准确,对早产的预测价值更优,经会阴与经阴道途径测量无明显区别。Objective:To analyze the application value of different ultrasound methods for measuring cervical length of women with different cervical shapes during the second trimester pregnancy.Methods:The prgnant women with high risk factors of preterm birth who had accepted ultrasound examination were selected as the research objects.According to the cervical morphology,they were divided into the group A(women with straight cervix)and group B(women with unstraight cervix).The cervical length of all included women was measured by transperineal straight line method and transperineal track method.And the cervical length and the predictive efficacy for preterm labor were compared between the two different methods.Results:There was no significant difference in the cervical length of women in group A between the two different measurement methods(P>0.05).In group B,the the cervical length measured by transperineal track method was significant longer than that of women by transperineal straight line method(P<0.001).As for women with cervical length less than 2.5 in group A,there was no significant difference in the rate of preterm labor between the two different methods(P>0.05).As for women with cervical length less than 2.5 in group B,the rate of preterm labor of women mearsued by transperineal track method was significant higher than that of women mearsued by transperineal straight line method(P<0.05).There were no significant difference in the sensitivity,the specificity,the positive predictive value,and the negative predictive value for predicting preterm labor of women in group A between the two different methods(P>0.05).In group B,the sensitivity,the specificity,the positive predictive value,and the negative predictive value for predicting preterm labor of women mearsued by transperineal track method were significant higher than those of women by transperineal straight line method(P<0.05).Conclusion:As for women with straight cervix,the cervical length and the prediction value of preterm labor by transperineal straight line
