A New Second-Trimester Scoring System To Predict Preterm Birth

Objective: To create a new scoring system for predicting preterm birth by incorporating second-trimester sonographic measurements, including cervical length, uterocervical angle, and lower uterine segment myometrial thickness, along with cervical dilation. Method: This prospective study included 252 pregnant women who were admitted to a university-affiliated research hospital between 16 and 24 gestational weeks. Participants were followed and categorized into two groups: preterm birth group (n=40) and term birth group (n=212). Cervical length, uterocervical angle, and myometrial thickness were measured and the predictive role of these parameters for preterm birth was evaluated. A new scoring system was developed based on the identified cut-off values. Results: A cervical length≤36.3 mm predicted preterm birth with 85% sensitivity and 73.1% specificity (p102.1 degrees predicted it with 92.5% sensitivity and 54.3% specificity (p
