Conditions

Lower uterine segment thickness associated with higher risk for cesarean delivery in pregnant women that indicated for labor induction. If this association occurs in general pregnant population, it may be a predictor for cesarean delivery. lower uterine thickness cesarean delivery

Interventions

Singleton pregnancy (both nullipara and multipara) with viable intrauterine fetus with cephalic presentation without history that is indicated to delivery by cesarean section, such as prior cesarean d

Diagnostic
