Is it possible to give birth naturally with a scarred uterus?

A scarred uterus can generally be delivered naturally, but the recovery of uterine scar and the condition of the fetus need to be strictly evaluated. If there is insufficient scar thickness, abnormal placental position, or fetal distress, vaginal delivery is not recommended.

A normal delivery with a scarred uterus requires that the lower uterine segment scar heals well and is more than 3 mm thick, the fetus is in the cephalic position, the maternal pelvic condition is normal, and there are no risk factors such as fetal intrauterine hypoxia. In clinical practice, about 60% of eligible women with scarred uterus can have a successful trial of vaginal delivery, but full fetal heart rate monitoring and an emergency cesarean section plan are required. The probability of uterine rupture is low during natural delivery, but once it occurs, a cesarean section must be completed within 5 minutes to ensure the safety of the mother and baby.

The risk of uterine rupture is significantly increased when there is poor healing of the previous cesarean section incision, the placenta is covered with scars from this pregnancy, multiple pregnancies, or the fetal weight exceeds 4,000 grams. Trial labor should be prohibited for those with a history of uterine rupture, scar thickness less than 2.5 mm, or irregular uterine contractions accompanied by scar tenderness. In this case, an elective repeat cesarean section is required at 38-39 weeks of pregnancy to avoid danger after the onset of labor.

It is recommended that scar thickness be monitored dynamically through ultrasound starting from 36 weeks of pregnancy, and the obstetrician will comprehensively evaluate the mode of delivery. During labor, choose a hospital with emergency facilities to avoid overuse of oxytocin. It is necessary to closely observe uterine contractions and bleeding volume after delivery, and be alert to delayed uterine rupture.
