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

Condition or disease Intervention/treatment
Labor Induction, Third Trimester 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.

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

Primary Outcome Measures :
  1. uterocervical angle [ Time Frame: once at the beginning of enrollment ]
    the angle between the lower segment of uterus and cervix
