The uterocervical angle and its relationship with preterm birth

Abstract

Wider UCA in the second trimester is related to sPTB. UCA measurement is a reproducible technique. UCA appears to increase from the first to the second trimester. Prospective studies, with ultrasound examinations aimed at measuring UCA in vivo, are needed to accurately assess the characteristics of this marker and its potential as a predictor of sPTB in clinical practice.
