Induction of labour is a widely used intervention on the modern labor. The Bishop score, since its description in 1964, remains the gold standard for assessing favorability for induction of labor. However, the preinduction {u2018}favorability{u2019} of the cervix as assessed by the Bishop score is very subjective and several studies have demonstrated a poor predictive value for the outcome of induction especially in women with a low Bishop score . The aim of this study was to evaluate the Transvaginalultrasonographic Measurements in predicting the success of induction of labour . Patients and Methods :In our study 70 women 35-42 weeks pregnancy underwent induction of labor. Before induction a digital examination of the cervix was performed & the Bishop score noted. Cervical length , posterior cervical angle& cervical funneling were then assessd by a transvaginal ultrasound. Results &conclusion : Successful induction correlated significantly with the Bishop score and ultrasonographically measured cervical length, posterior cervical angel. and ultrasound measurments appear to be better than the Bishop score in prediction of successful vaginal delivery
