Abstract

Objectives: In recent years, in addition to cervical length measurement, a new ultrasonographic parameter has been defined as uterocervical angle (UCA), which can be used in the prediction of preterm labor. In this study,we evaluated the place of uterocervical angle in predicting the latent phase duration in postterm pregnancies.

Material and methods: This prospective study consists of 90 pregnant women aged between 18 to 40 years who were hospitalized with a diagnose of late term pregnancy. Pregnant women with a latent phase duration of 1200 minutes or less were defined as Group 1. Patients with latent phase duration over 1200 minutes were defined as Group 2. All patients' age, BMI, smoke, cervical length measurements, uterocervical angle, latent and active phase of labor durations, length of the third stage and delivery types were compared.

Results: The UCA median value of group 1 was 120 (94-147), and group 2 was 99 (94-105) (p < 0.001). CL medians of Groups 1 and 2 were 29 (17-43) and 28 (27-41) respectively (p: 0.871). UCA (AUC: 0.917, p < 0.0001) significantly predicted prolonged latent phase duration. Optimal cut off value was obtained at the value of 105 degree (100% sensitivity, 75% specificity) for UCA. Kaplan-Meier survival analysis showed that duration of labor was significantly higher in a group with low UCA (p: 0.013).

Conclusions: UCA can be a successful tool that can be used to predict duration of labor in cases of postterm pregnancies with medical induction.

子宫宫颈前角:它是一个超声筛查工具，估计潜伏期持续时间在足月后妊娠?

目的：近年来，除了宫颈长度测量外，还定义了一个新的超声参数，即子宫颈角（UCA），可用于预测早产。在这项研究中，我们评估了子宫颈角在预测足月妊娠潜伏期持续时间中的位置。材料和方法：这项前瞻性研究由90名年龄在18至40岁之间的孕妇组成，她们因诊断为晚期妊娠而住院。潜伏期为1200分钟或更短的孕妇被定义为第1组。潜伏期超过1200分钟的患者被定义为第2组。比较所有患者的年龄、BMI、吸烟、宫颈长度测量、子宫颈角、产程潜伏期和活动期、第三阶段长度和分娩类型。结果：第1组的UCA中位数为120（94-147），第2组为99（94-105）（p＜0.001）。第1组和第2组的CL中位数分别为29（17-43）和28（27-41）（p：0.871）。UCA（AUC:0.917，p＜0.0001）可显著预测潜伏期延长。UCA的最佳截止值为105度（100%灵敏度，75%特异性）。Kaplan-Meier生存率分析显示，低UCA组的产程显著延长（p：0.013）。结论：UCA是一种成功的工具，可用于预测药物诱导的足月妊娠的产程。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
