Diagnostic accuracy of posterior cervical angle, and cervical length in Prediction of Successful labor induction

Abstract

Objective : To study the evaluation of the value of the posterior cervical angle (PCA) and cervical length, measured by transvaginal ultrasonography, compared with the Bishop score in the prediction of successful labor induction. Background : Induction of labor represents a common procedure in everyday obstetric practice. It is used in 30 e 40% of women in labor. Induction of labor refers to the initiation of uterine contractions before the spontaneous onset of labor, which may be either elective or indicated. Patients and methods : A prospective observational study was conducted in the Department of Obstetrics and Gyne-cology, Shebin El-Kom University Hospitals, from March to December 2020. Results : Our study included 90 candidates for labor induction, after assessment of PCA and cervical length (by transvaginal ultrasonography) and Bishop score. Conclusion : In this study, we found that success of labor induction can be highly predicted by transvaginal sonography of cervical length and PCA, as it is more objective and accurate than the Bishop score, This is owing to the signi fi cant correlation between successful labor induction and PCA.
