Abstract
PURPOSE: To investigate changes in uterine flexion after cesarean delivery in comparison with vaginal delivery, and their relationship with the presence of deficient cesarean section scars. METHODS: In 147 women who had a vaginal delivery and 101 women who had a cesarean delivery, transvaginal ultrasonographic photographs of the uterus were obtained at the first trimester of pregnancy and at 1 month postpartum, and they were reviewed to determine changes in uterine flexion. The presence of a deficient cesarean section scar was also reviewed in women with a cesarean section. RESULTS: Changes in uterine flexion were observed more frequently among the woman with a cesarean delivery than in those with a vaginal delivery. The incidence of post-flexed uterus during puerperium tended to increase depending on the number of cesarean sections the woman had undergone. In the women with a cesarean section, changes in uterine flexion were more frequently observed in the women with a deficient cesarean section scar than in those without one. CONCLUSION: Changes in uterine flexion after birth occurred more frequently in the women who had a cesarean delivery than in those who had a vaginal delivery, especially in the presence of a deficient cesarean section scar.
