Outcomes of Uterine Rupture in the Setting of the Unscarred Compared With the Scarred Uterus.

Abstract

Uterine rupture is a rare obstetric complication that is associated with maternal and neonatal morbidity and mortality. The aim of this study was to examine uterine rupture and its outcomes in the setting of the unscarred compared with the scarred uterus. A retrospective observational cohort study was performed examining all cases of uterine rupture in three tertiary care hospitals in Dublin, Ireland, over a 20-year period. The primary outcome was perinatal mortality rate with uterine rupture, which was 11.02% (95% CI 6.5-17.3). There was no significant difference in perinatal mortality between cases of scarred and unscarred uterine rupture. Unscarred uterine rupture was associated with higher maternal morbidity , defined as major obstetric hemorrhage or hysterectomy.
