Obstetric Uterine Rupture of the Unscarred Uterus: A Case Series of Six

Objectives: Uterine rupture in an unscarred uterus is a reality. It is a rare obstetrical complication that requires prompt diagnosis and immediate management. The aim of our study is to describe and analyze the epidemiological characteristics, maternal and fetal prognostic elements, and different therapeutic modalities of uterine rupture in an unscarred uterus. Methods: This is a descriptive retrospective study spanning a 6-year period from 2017 to 2022. Results: The incidence was 1.7/10,000 deliveries, with a mean maternal age of 31.3 years. All patients were multiparous, and rupture occurred during labor in all cases. The main clinical presentation was a non-reassuring fetal heart rate tracing. Surgical treatment was conservative in 4 out of 6 cases. There were no maternal deaths, but the fetal prognosis was severe, with two fetal deaths. Conclusion: Unscarred uterine rupture is a rare but serious obstetric complication. In this series, maternal-fetal morbidity and mortality were high, consistent with the literature.
