Abstract: Uterine rupture is a perinatal complication that seriously threatens the life of the mother and fetus. With the opening of the fertility policy，the incidence of uterine rupture in pregnant women in China is on the rise. The main cause of uterine rupture is scarred uterus. The cause of scarred uterus includes not only cesarean section but also the history of uterine surgery with non-obstetrical factors，which is also the most easily neglected cause. Uterine rupture of scarred uterus often occurs in the process of vaginal delivery，but placental implantation can lead to spontaneous uterine rupture in the middle and third trimester of pregnancy，which is worthy of clinical attention. Abdominal pain，vaginal bleeding，and decreased fetal heart rate are common clinical manifestations of uterine rupture，while occult uterine rupture in the middle and third trimester of pregnancy is often characterized by abdominal pain and shock. Therefore，the early identification and timely surgical treatments of uterine rupture are closely related to the maternal and fetal outcomes. We focus on the common causes and clinical manifestations of uterine rupture，hoping to improve the vigilance of clinicians and improve the maternal and fetal outcomes.
