Value of Measuring Cervical Angle and Length by Ultrasound in Prediction of Successful Induction of Delivery

Study Overview
=================
Brief Summary
-----------------
Seventy ladies indicated for induction of delivery will be recruited. Two ways of assessment of their cervices will be done before actual induction of labor. First, ultrasound will be done to assess the angle and the length of the cervix. Then vaginal examination will be done to assess the characteristics of cervix. Analysis will be done to identify the best predictor of successful induction of labour.

Detailed Description
-----------------
Seventy patients indicated for induction of labor will be recruited. Two ways of assessment of their cervices will be done before actual induction of labor. First, transvaginal ultrasound will be done to assess the posterior angle and the length of the cervix. Then vaginal examination will be done to measure the Bishop score. Analysis will be done to identify the best predictor of successful induction of labour.
