Abstract          1) To compare the predictive value of transvaginal ultrasonographic measurement of cervical length versus Bishop score prior to induction of labour in predicting the mode of delivery and maternal and foetal outcome. 2) To estimate the most useful cutoff points for the two methods. Material and Methods: The study was conducted at department of obs and gynae at pannadhay rajkiya mahila chikitsalaya RNT medical college, Udaipur. This study is a prospective observational study. In this study 100 patients with gestational age between 37-42 weeks with singleton pregnancy admitted for induction of labor are enrolled. After informed and written consent of patients, the cervical length was measured by transvaginal ultrasound and then Bishop Score was assessed by digital examination. Induction of labor done by tab misoprost 25microgram per vaginally .Predictive values for successful labour induction within 24hrs was detected and compared between bishop score and cervical length measured by TVS. Results: TVS cervical length and Bishop score have significant correlation in predicting the success of induction of labour. Cervical length is the better predictor of the likelihood of vaginal delivery within 24hrs. Out of 100 enrolled patients, 80(80%) patients delivered vaginally and 20(20%) patients delivered by caesarean section. In the receiver operating characteristic curves, the best cutoff points for the prediction of successful induction was <27mm for cervical length and> 4 for the Bishop Score. Conclusion: Transvaginal sonographic measurement of cervical length is a better predictor of the likelihood of vaginal delivery within 24hrs of induction when compared to Bishop Score.
