Abstract
INTRODUCTION: The induction of labor (IOL) is a common intervention in obstetrics, and its success is assessed by the Bishop score routinely in all patients prior to IOL. OBJECTIVES: To assess Bishop score vs. transvaginal ultrasound (TVS) for predicting successful labor induction by prostaglandins. MATERIALS AND METHODS: The study included patients with ≥37 weeks of pregnancy with nonrandom opportunity sampling. The cervix was assessed by TVS and compared with the Bishop score. The labor was induced with the tablet misoprostol or dinoprostone gel. RESULT: The labor induction was successful in 80% of patients. The TVS cervical score had better sensitivity and specificity than the Bishop score. CONCLUSION: TVS is an objective method for assessing the cervix before induction and can be used as an adjunct to the Bishop score.
