Cervical Sliding Sign to Predict Outcome of Induction of Labor

Assess the role of transvaginal ultrasound specifically a sign called cervical sliding sign, in the prediction of success of induction of labor. The prediction of outcome of induction of labor has always been an important topic to all obstetricians. Bishop score is traditionally considered reliable way to predict the outcome of induction of labor by assessing the cervical dilatation, effacement, position, and consistence and assessing the level of the fetal head in the birth canal. Since The bishop score remains a highly subjective method for prediction of outcome of induction of labor, the use of sonographic measurements such as cervical sliding sign can be a better predictor of successful induction of labor.The presence of CSS was defined as the sliding of the anterior cervical lip on the posterior one under gentle pressure of the transvaginal probe. Patients undergoing induction of labor with misoprostol will be checked for the cervical sliding sign. The mode of delivery, induction to active labor time and active labor to delivery time will be recorded and analysed to assess whether the sliding sign is an independent predictor of success of induction.
