Uterocervical Angle Assessment in the Second Trimester of Pregnancy as a Predictor for Preterm Delivery

Abstract

Background: The wide uterocervical angle (UCA) has been identified as a predictor of preterm delivery, and the goal of this study is to see how accurate UCA is at predicting spontaneous preterm birth in the second trimester. The aim of study is early prediction of preterm  labor by uterocervical angle measurement using transvaginal sonography (TVS) in the second trimester of women at low risk for  spontaneous preterm birth (SPB).

Methods: This is a prospective cohort study including seventy pregnant women in the second  trimester (16-28weeks). They were classified into to preterm (group 1) and term (group 2) according to delivery of 28 and 42 women in  each group, respectively. TVS was performed for all participants with measuring UCA.

Results: This study shows that all ultrasonographic  parameters showed the mean UCA was 124.74±19.69 and 85.95±8.32 degrees in preterm and fullterm delivery, respectively, it had  statistically highly significant difference (p <0.001).

Conclusions: An elevated risk of spontaneous preterm birth was linked to a wide UCA  found during the second trimester. The uterocervical angle may be utilised as a screening tool for spontaneous preterm birth, according  to this study.
