The aim of the study was to investigate if there are changes in elastographic parameters in the cervix at term around the time of delivery and if there are differences in the parameters between women with spontaneous labor and those without labor (labor induction). Nulliparous women at 36 weeks of gestation eligible for vaginal delivery were enrolled. Cervical elastography was performed and cervical length were measured using the E-CervixTM system (WS80A Ultrasound System, Samsung Medison, Seoul, Korea) at each weekly antenatal visit until admission for spontaneous labor or labor induction. E-Cervix parameters of interest included elasticity contrast index (ECI), internal os strain mean level (IOS), external os strain mean level (EOS), IOS/EOS strain mean ratio, strain mean level, and hardness ratio. Regression analysis was performed using days from elastographic measurement at each visit to admission for delivery and the presence or absence of labor against cervical length, and each E-Cervix parameter fitted to a linear model for longitudinal data measured repeatedly. A total of 96 women were included in the analysis, (spontaneous labor, n = 39; labor induction, n = 57). Baseline characteristics were not different between the two groups except for cesarean delivery rate. Cervical length decreased with advancing gestation and was different between the two groups. Most elastographic parameters including ECI, IOS, EOS, strain mean, and hardness ratio were significantly different between the two groups. In addition, ECI, IOS, and strain mean values significantly increased with advancing gestation. Our longitudinal study using ultrasound elastography indicated that E-cervix parameters tended to change linearly at term near the time of admission for delivery and that there were differences in E-Cervix parameters according to the presence or absence of labor.

Successful Induction

Abstract Background Induction of labor is commonly performed in obstetric practice. Many methods have been suggested as good predictors of the outcome of labor induction, yet none of them is satisfactory enough. Objective To assess cervical length and uterocervical angle measured by transvaginal ultrasound as predictors of successful induction of labor. Methodology Prospective cohort study was conducted in a university-affiliated hospital over 150 nulliparous women undergoing induction of labor, in the period between May 2018 and August 2019. Transvaginal sonographic measurement of cervical length and uterocervical angle was done before induction of labor by prostaglandins. The patients were followed up till delivery and the outcome was recorded. Results The best cut-off value of cervical length for prediction of success of labor induction was 32.3 mm with 60% sensitivity and 56% specificity and the best cutoff value of uterocervical angle was 110.2 degrees with 87% sensitivity and 93% specificity. The cervical length showed a significant negative correlation while the uterocervical angle showed a significant positive correlation with the success of labor induction. Conclusion Cervical length and uterocervical angle are good predictors of successful labor induction.
