Background: The process of labor has always been elusive and difficult to grasp till this current era. What is even more elusive knows when it would happen and when to intervene. Throughout the medical literature there has been reliance on clinical examination to predict successful induction. with the advent of ultrasonography this process of relying on subjective clinical data has shifted towards combining both the skills of the examiner with the subjective information from ultrasonography. Objective: Comparing between Bishop Score and transvaginal cervical assessment of prior to induction of labor in prediction of successful. Patients and methods: This study was conducted at Obstetrics and Gynecology Department, Damanhour Teaching Hospital, from January of 2018 and December of 2018 and included a sample of 200 pregnant women. The mean age of mother in our study was 24±3.75 years, the mean BMI was 25.85±4.33. The mean gestational age by U/S was 38.9±2 weeks. The mean bishop score was 7.20 ± 1.80, the mean cervical length was 17.54 ± 4.64, the mean posterior cervical angle was 116.3 ± 14.23. Results: The results of this study showed that the correlation between labor induction prediction of success using bishop score and ultrasound. The mean bishop score was 7.20 ± 1.80, the mean cervical length was 17.54 ± 4.64, the mean posterior cervical angle was 116.3 ± 14.23. it was found that there was a positive significant correlation between successful induction and pre-induction bishop score , posterior cervical angle and cervical length. Conclusion: In this study we found that successful induction correlated significantly with the Bishop score and ultrasonographic cervical length & posterior cervical angle.
