ABSTRACT: Objectives: To assess the role of mid-trimester transvaginal sonographic
assessment of cervix in predicting the risk of primary cesarean section. Methods:
Hundred pregnant women, who attended out-patient department of Tata Main
Hospital for ante natal examination, from 1st December 2011 to 1st December 2012, were taken up for the study. Only those who had confirmed dates
were included in the study. Transvaginal sonography was done at 18 - 26 week to
measure cervical length. Parameters studied were gestational age at delivery,
whether spontaneous or induced, duration of labor, pregnancy outcome and mode
of delivery and indication for cesarean section. Results: Majority of LSCS were
in the group with cervical length ≥4 cm (57.1%) with “p” value of predictive value of cervical length as a predictor
of mode of delivery was 54.8%, 91.4%, 82.1% and 73.6% respectively. R2 (coefficient of determination) was 0.271. Conclusion: Transvaginal cervical
length measurement at mid trimester can be used as a predictive tool to
determine the risk of primary cesarean section as well as the need of induction
of labor.
