Abstract

Objective: To compare elastosonography and digital examination of cervix for consistency in the prediction of successful vaginal delivery.

Methods: A total of 64 pregnant women with the indication of induction of labor (IOL) were enrolled to the study. The uterine cervix is evaluated before and after the IOL with elastosonography and digital examination for consistency and sonography for length. Methods were compared in regard to the prediction of successful vaginal delivery.

Results: The median of gestational age was 41.00 (IQR = 2.32). Out of 64 participants, 40 (62.5%) had vaginal delivery and 24 (37.5%) had cesarean delivery. The preinduction and postinduction elastosonographic indices were insignificant in delivery groups. The preinduction and postinduction evaluations of cervical consistency with digital examination were significant within vaginal delivery group (p = 0.046), whereas it was insignificant within cesarean delivery group and between the delivery groups. The preinduction and postinduction Bishop scores were significant within vaginal delivery group (p = 0.005), whereas it was insignificant within cesarean delivery group and between the delivery groups. Postinduction Bishop score was significant between the delivery groups.

Conclusion: Evaluation of cervix for consistency with either elastosonography or digital examination was found to be insignificant in prediction of successful vaginal delivery after IOL with oxytocin.
