Epidemiology

It is estimated that one uterine rupture occurs for every 5,000 to 7,000 births. Uterine rupture is more common in women with prior cesarean delivery. The rate of uterine rupture is approximately 1% for women with one previous cesarean delivery versus 3.9% for those with greater than one previous cesarean delivery. The rate of uterine rupture with an unscarred uterus has been found to be approximately one rupture per 10,000 to 25,000 deliveries
