Induction of labor (IOL) refers to the artificial initiation of uterine contractions before their spontaneous onset at or beyond the age of viability with the sole aim of delivery of the feto-placental unit where the benefit of pregnancy termination exceeds its prolongation. Certain maternal, fetal characteristics and ultrasound parameters have been associated with higher odds of IOL success.
AIM OF THE WORK:
The aim of this study was to assess the value of myometrial thickness
measurement using trans-abdominal ultrasound in predicting labour induction
success.
PATIENTS AND METHODS:
Our study recruited 60 pregnant women indicated for IOL at term. Background characteristics were collected, the Bishop score of each case was calculated, sonographic myometrial thickness was assessed using an abdominal probe, and labor was induced using either dinoprostone and oxytocin.
RESULTS:
Using a cut-off value of 4 mm thickness, lower-segment thickness can predict the success of normal cases with 62% sensitivity and 66% specificity. A high positive predictive value of 84.8%.
