OBJECTIVE: To examine risk factors and evaluate maternal and neonatal outcomes in eight cases of rupture of the unscarred uterus. Design: In this retrospective study, 8 cases of unscarred uterine rupture diagnosed in our clinics between 1985 and 2004 were included. Setting: Department of Obstetrics and Gynecology, School of Medicine, Süleyman Demirel University and Isparta Women’s and Children’s Hospital Patients: Eight cases of unscarred uterine rupture in 63489 vaginal delivery Main outcome measures: Etiology, risk factors, clinical findings and fetal-maternal outcomes. RESULTS: From 1985 through 2004, we identified 8 uterine ruptures in women without previous cesarean deliveries. The incidence of rupture of an unscarred uterus was in 7937 deliveries. The mean age, the mean gestational age and the mean parity were 31.4 (year), 39.2 (week) and 5.4, respectively. Associated factors included application of fundal pressure (1 case), oxytocin use (3 cases), prostaglandin use (1case), breech presentation (2 cases) and use of vacuum or forceps (1 case). Five (%62.5) cases were identified from 1985 through 1994 and 3 (%37.5) cases were idendified from 1995 through 2004. CONCLUSION: Recent advances in obstetric practice and modern medicine have resulted in a decrease in ruptures of the unscarred uterus.
