Outcomes of uterine rupture in unscarred compared with the scarred uterus: analysis of 61 complete uterine rupture

BACKGROUND: Uterine rupture, though rare, is a severe complication during pregnancy. While a scarred uterus is a well-recognized high-risk factor for uterine rupture during pregnancy, the significant risk of complete uterine rupture in non-scarred uteri cannot be overlooked in clinical practice. METHODS: This retrospective multicenter study collected data on all cases of complete uterine rupture that occurred from January 2012 to December 2016 across 11 hospitals in Beijing and 2 hospitals in the Ningxia Hui Autonomous Region. The study examined the clinical characteristics and outcomes for both mothers and fetuses. RESULTS: = 0.88). CONCLUSION: In obstetric clinical practice, it is crucial to focus not only on patients with uterine body scars and the risk of uterine rupture during pregnancy and childbirth, but also on the possibility of uterine rupture in other patients who may have potential uterine scars. These cases may be easily overlooked, leading to delayed diagnosis and, consequently, adverse outcomes for both mother and fetus.
