Clinical Presentation and Diagnosis
- The clinical presentation of uterine rupture includes abnormal fetal heart rate patterns in over 70% of cases
- The diagnosis of uterine rupture is confirmed intraoperatively in most cases, with ultrasound having limited sensitivity
- Uterine rupture often presents with sudden abdominal pain and cessation of contractions, observed in more than 80% of cases
- The use of continuous electronic fetal monitoring can help detect early signs of uterine rupture, but it is not definitive
- The use of MRI can aid in diagnosing uterine rupture in uncertain cases, especially when ultrasound findings are inconclusive

- In women with previous uterine rupture, the recurrence risk for subsequent pregnancies is approximately 4%
- The global incidence of uterine rupture is estimated to be around 1 in 3000 births, but higher in low-resource settings
- Uterine rupture in unscarred uteri predominantly occurs due to obstructed labor or traumatic injury, but is very rare, rate of about 0.006%
Incidence and Epidemiology of Uterine Rupture Interpretation
Management, Treatment, and Follow-up
- The median time from uterine rupture diagnosis to maternal stabilization is approximately 30 minutes
- The maternal complication rate from uterine rupture is significantly reduced with timely surgical intervention
Management, Treatment, and Follow-up Interpretation
Maternal and Neonatal Outcomes
- Uterine rupture is responsible for about 0.2% of maternal deaths during labor
- In cases of uterine rupture, fetal mortality rates can reach up to 15-30%
- Uterine rupture results in maternal hysterectomy in approximately 10% of severe cases
- Uterine rupture is associated with increased neonatal intensive care admissions, affecting up to 30% of cases
- The maternal morbidity associated with uterine rupture includes hemorrhage, hysterectomy, and injury to adjacent organs, occurring in about 15% of cases
- The average blood loss during uterine rupture is around 1000-2000 mL, which can lead to hypovolemic shock
- The mortality rate associated with uterine rupture has decreased over the past decades due to better obstetric care
- Uterine rupture significantly increases the risk of postpartum hemorrhage, accounting for up to 25% of severe postpartum hemorrhage cases
- Uterine rupture can cause placental abruption in addition to fetal distress, contributing to emergency delivery
- Neonatal mortality rates in cases of uterine rupture can be as high as 20-30%, depending on the timeliness of intervention
- The overall morbidity and mortality risks associated with uterine rupture emphasize the importance of prenatal counseling and careful labor management
- The average hospital length of stay after surgical repair of uterine rupture is approximately 5-7 days, depending on severity
- Uterine rupture in low-resource settings often results in higher maternal and neonatal morbidity due to limited access to emergency surgical care
