Uterine Artery Doppler Indices and Uterocervical Angle Measurment in Prediction of Preterm Labor
Egypt47 participantsStarted 2026-01-15
Plain-language summary
The goal of this observational study is to evaluate the role of uterine artery doppler indices and uterocervical angle measurement in prediction of preterm labor .The main question it aims to answer is:
Does combination of both uterine artery doppler indices and uterocervical angle measurement increase sensitivity and specificity for prediction of established preterm labor ? Participants already performing uterine artery doppler as part of their regular antenatal care .measurement of anterior uterocervical angle will be added between 24 to 34 weeks gestation to predict preterm labor in candidates .
