dc.description.abstractObjective: To evaluate the efficiency of cervical sonography in determination of preterm birth in singleton and twin pregnancies. Materials and Methods: A total of 78 women (56 with singleton and 22 with twin pregnancies) with preterm labor who were admitted to our department between 25 and 36 weeks' gestation were enrolled in the study. Cervical length and the presence of cervical funneling were evaluated by transvaginal sonographic scan. For singleton and twin pregnancies reaching >= 37 and >= 34 weeks' gestation respectively, were accepted as good perinatal outcome. The cut-off values for cervical length were set at <35 mm for singleton and <25 mm for twin pregnancies. Results: Sonographic evaluation and delivery weeks for singleton and twin pregnancies were 33 (25-36) and 36 (26-40) weeks, and 31 (25-33) and 34 (31-36) weeks, respectively. A cervical length <35 mm for singleton pregnancies, <25 mm for twins have 67.9% and 57.1% sensitivity, 46.4% and 86.7% specificity, 55.9% and 66.7% positive predictive and 59.1% and 81.3% negative predictive values for the determination of preterm birth, respectively. The presence of cervical funneling for singleton and twin pregnancies determined preterm birth with sensitivity of 83.3% and 55.6%, specificity of 50% and 84.6%, positive predictive value of 44.1% and 71.4%, negative predictive value of 86.4% and 73.3%, respectively. Conclusion: Cervical sonography after 25 weeks' gestation can determine preterm birth with high sensitivity and negative predictive value in twin pregnancies presented with preterm labor. However, for singleton pregnancies the presence of cervical funneling has high sensitivity and negative predictive values for the determination of preterm birth.en_US
