Rupture of the pregnant uterus is an uncommon but severe obstetrical event, which is associated with high perinatal and maternal morbidity and mortality. It occurs mostly secondary to a previous caesarean section, making this its main risk factor with an incidence of around 1%. The estimated incidence of a rupture of the unscarred uterus is 1/8000 to 15,000 deliveries or, as investigated by the World Health Organization (WHO), 0.006%. Rupture in a primigravid patient is extremely rare and, in most cases, totally unexpected. The incidence of uterus rupture in general is significantly higher in developing countries than in developed countries caused by worse antenatal and obstetric care high frequency of home deliveries with prolonged labor, and grand multiparity.
