The role of ultrasonographic-guided insertion of cervical ripening balloon: A prospective study.

Objectives: Cervical ripening balloon (CRB) is a frequently used technique for non-pharmacologically induction of labor (IOL) in presence of an unfavorable cervix. Successful ripening requires a correct placement of the CRB in the cervical canal. The objective of this study was to evaluate whether ultrasound-guided CRB insertion results more effective in inducing cervical changes than speculum-guided placement.
