Abstract

Aim. To identify risk factors for developing cesarean uterine scar defect using sonographic and the scar's morphological characteristics. Materials and methods. This retrospective study of164 women with a cesarean uterine scar included 98 (59.7%) women with normal uterine scar thickness (group I) and 66 (40.3%) with thinned uterine scars (group II). We used the data of hospital medical records, antenatal care cards, and the morphology reports of uterine scars after repeat cesarean section. Results. The groups had significant differences in uterine position, active phase of labor, suture technique, infectious complications before or after surgery, intraoperative blood loss, and operating time (all P<0.001). There were also significant differences in uterine scar morphological characteristics (P<0.001). Conclusion. Longer operating time, infectious complications, and uterine retroflection are risk factors for the development of a dehiscent scar. In contrast, intraoperative blood loss < 400 ml and double-row uterine closure technique are factors that reduce the risk of a scar defect.
