It is a prospective study conducted in the Institute of Obstetrics and Gynecology. The objective is 1) To study the relationship between cervical length at midpregnancy and gestational age at delivery, onset of labour – spontaneous or induced, mode of delivery and caesarean section due to failed induction. 2) To determine the mean cervical length in our population.

MATERIALS AND METHODS:

                     500 antenatal women were included in the study. Transvaginal ultrasound was done between 20–24 weeks and cervical length was recorded. The women were subsequently managed according to the hospital protocol. The women were followed up to term and their labour outcome was recorded.

RESULTS

             Lower the cervical length, higher is the risk of preterm labour. Increase in the cervical length at midtrimester is associated with increase in the incidence of postterm pregnancy, failure of spontaneous onset of labour and cesarean section in view of failed induction.
