Abstract
Background: Modern obstetrics inducts 20% of all deliveries. Because not all inductions result in a vaginal birth, finding the best way to predict success is essential. The lower uterine segment thins with gestational age. B-mode ultrasonography detects this. Measuring the LUS myometric thickness quantifies the risk of uterine rupture during vaginal delivery following a cesarean section. Aim of the Work: to evaluate different sonographic characteristics for the cervical and lower uterine segments in in order to predict labour induction and vaginal delivery. Results: Induction was successful in majority of cases (96.2%). Mean±SD of Time until active phase and delivery was 4.1±2.7 and 7.6±3.1 hours respectively and Normal vaginal delivery was the most frequent mode in majority of cases (93.3%). Cases with successful induction statistically had non-significant higher Effacement and Bishop Score, but had significant lower cervical length and LUS thickness and so higher Manipal score. Conclusion: we were able to present data that cervical structural changes occurred at the internal OS level, i.e., shortening through funneling. These structural changes may be the determining factor for successful induction of labour.
