Uterocervical angle measurements in pregnant women with idiopathic polyhydramnios were appraised for their predictive value for spontaneous preterm labor.
In this prospective study, we included nulliparous and multiparous pregnant women diagnosed with idiopathic polyhydramnios at 24-28 weeks at our polyclinic; the uterocervical angle and cervical length were measured by transvaginal ultrasound at the time of diagnosis. Routine pregnancy follow-up was done by our team and gestational age at delivery and maternal-fetal outcomes were noted.
In total, 24 patients delivered before 37 weeks and 36 patients delivered at 37 weeks or later. Preterm labor subjects had larger UCA values (126.7±12.9° vs. 100.8±16.2°) and term labor patients had larger cervical length values (34.3±4.5 mm vs. 40.6±5.2 mm). In women with idiopathic polyhydramnios, the area under the curve for the uterocervical angle was 0.885 (p<0.001) and it was 0.823 for the cervical length (p<0.001).
The uterocervical angle, a sagittal transvaginal cervical image measurement, is a practical method that successfully predicts spontaneous preterm labor risk in singleton pregnancies with idiopathic polyhydramnios. In addition, the uterocervical angle displayed greater sensitivity, but lower specificity, compared with cervical length measures.
评估特发性羊水过多孕妇的子宫颈角测量值对自发性早产的预测价值。
在这项前瞻性研究中，我们纳入了在我们的妇产科诊所被诊断为特发性羊水过多的初产妇和经产妇；在诊断时通过经阴道超声测量子宫颈角和宫颈长度。由我们的团队进行常规妊娠随访，并记录分娩时的胎龄和母婴结局。
共有 24 名患者在 37 周前分娩，36 名患者在 37 周或以后分娩。早产组的 UCA 值较大（126.7±12.9° vs. 100.8±16.2°），足月产组的宫颈长度值较大（34.3±4.5 mm vs. 40.6±5.2 mm）。在特发性羊水过多的女性中，子宫颈角的曲线下面积为 0.885（p<0.001），宫颈长度为 0.823（p<0.001）。
子宫颈角是一种矢状经阴道宫颈图像测量，是一种实用的方法，成功地预测了特发性羊水过多的单胎妊娠自发性早产的风险。此外，与宫颈长度测量相比，子宫颈角显示出更高的敏感性，但特异性较低。
