A urinary balloon catheter will be placed through the cervix into the lower uterine segment and the bulb inflated with 40ml of saline. The catheter will be taped to the patient's thigh and placed under traction using a liter bag of saline. The catheter will be deflated and removed after 6 hours. If spontaneously expelled from the uterus, time of expulsion will be noted. Six hours after insertion of catheter, a digital exam will be performed and Bishop score recorded. If no active labor at time of catheter removal or expulsion, standardized protocol of oxytocin will commence. Labor management will be at the discretion of the physician.

Prepidil Only : Prepidil gel will be inserted into the vaginal fornix according to manufacturer's direction. No oxytocin or other intervention will commence until 6 hours after insertion of gel. Six hours after insertion of gel, digital exam will be performed and Bishop score recorded. If no active labor 6 hours after the administration of gel, standardized protocol of oxytocin will commence. Labor management will be at the discretion of the physician.

A urinary balloon catheter will be placed through the cervix into the lower uterine segment and the bulb inflated with 40ml of saline. The catheter will be taped to the patient's thigh and placed under traction using a liter bag of saline. Prepidil gel will be inserted through the catheter into the lower uterine segment, in a dose equivalent to manufacturer's recommendation. No oxytocin or other intervention will commence until 6 hours after insertion of the catheter and administration of prepidil gel (even if catheter is spontaneously expelled). After 6 hours, digital exam will be performed and Bishop score recorded. If no active labor, standardized protocol of oxytocin will commence.

Region of Enrollment

The primary outcome of this study is vaginal delivery of a liveborn singleton pregnancy. The outcome is considered a vaginal delivery if accomplished by spontaneous vaginal delivery, operative forceps or vacuum forceps. The alternate outcome is delivery by cesarean section.
