Aims: This study aims to determine the effect of the myometrial thickness on the amount of postpartum bleeding and to investigate its role as an auxiliary method in predicting postpartum hemorrhage.
 Methods: This prospective study includes 305 pregnant women in two groups, vaginal delivery, and cesarean section patients. The fundal, mid anterior, and lower uterine segment myometrium thicknesses were measured. In the postpartum period, the amount of bleeding and the type of delivery was recorded, and the relationship between myometrial thickness measurements was determined.
 Results: The amount of bleeding in the patients who had a cesarean section was higher than in those who had a vaginal delivery (p
