Abstract: Complete uterine rupture is a serious obstetrical complication with a low incidence, but once it happens, it will have disastrous consequences for both mother and child, which is one of the important criteria for measuring the quality of obstetrics in a region. The incidence of complete uterine rupture tends to increase due to the increase frequency of cesarean section and the conduction of vaginal birth after cesarean(VBAC), but unscarred uterus rupture carried more catatrophic outcome. The pregnancy outcome of uterine rupture varies in different country and region and in different periods. The complication are more severe in the low-income countries due to poor economic and medical resourceｓ，ｅspacially in perinatal outcomes. Most uterine ruptures are not caused by a single high-risk factor, of which scarred uteri following cesarean section is the most common risk factor, meanwhile the other factors including dystocia, lack of prenatal care, inappropriate obstetric interventions. The period from suspected uterine rupture to delivery exceeding 30 minutes significantly increased the risk of perinatal death. Obstetricians need to identify the high-risk factors of uterine rupture early and strengthen the management of high-risk pregnant women. Once a uterine rupture occurs, immediately terminate the pregnancy to ensure the safety of the mother and child. The simultaneous development of social support systems and medical care can better improve the health of mothers and infants.
