Uterocervical Angle in Induction of Labor

Uterocervical Angle in Success of Induction of Labor

To evaluate the performance of uterocervical angle (UCA) in the prediction of labor induction.

Study Overview

• Status: Completed
• Conditions: Labor Induction, Third Trimester
• Intervention / Treatment: Other: uterocervical angle

Detailed Description

Induction of labor is a common procedure in obstetrics. In recent years, uterocervical angle (UCA) emerged as a new ultrasound parameter in the prediction of labor. Dziadosz et al concluded that the performance of UCA was even better than the cervical length in their cohort. A wide UCA during second trimester shown to have an increased risk of preterm labor and narrow angle was less likely to have labor.

The investigators are aimed to investigate predictive role of both cervical length and UCA in the labor induction in third trimester of pregnancy.The investigators focused on nulliparous women who are taking dinoproston for the cervical preparation and aim to measure their UCA.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Induced labor in term pregnancies; 100 singleton nulliparous patients are planning to complete the study period. Study group constitute of third trimester pregnancies between 37-40 weeks of gestation. All participants were nulliparous and had no systemic illnesses. The uterocervical angle will be measured in all participants before the induction of labor.	Other: uterocervical angle; uterocervical angle is the angle between lower segment of uterus and cervix
