Objective:
To assess the frequency of uterine ruptures, clinical characteristics, and maternal and neonatal outcomes in a tertiary referral center.
Methods:
Information on complete uterine rupture between July 2010 and June 2022 was investigated retrospectively at a tertiary center.
Results:
There were 42 cases of complete uterine rupture in 144 474 deliveries, with an incidence rate of 0.029%. Twenty-seven cases had a scarred uterus and 15 had an unscarred uterus; Rupture of the lower uterine segment was predominant in the scarred uterus, whereas rupture of the body of the uterus was predominant in the non-scarred uterus (P ≤ 0.001). Newborns with Apgar score of 7 or less at 1 min in the non-scarred uterus group was more than that in the scarred uterus group (P = 0.001). There were no significant differences in the history of gynecologic surgery, induction of labor, mode of delivery, clinical features, maternal outcomes, neonatal weight, preterm birth rate, 5-min Apgar score, or neonatal mortality between the two groups (P > 0.05).
Conclusion:
The clinical manifestations of uterine rupture are mainly abdominal pain, abnormal fetal heartbeat, or vaginal bleeding. Attention should also be paid to the history of previous uterine surgery. Strict prenatal management, early identification, and aggressive management can help improve maternal and child outcomes. Hysterectomy is not imperative.
