Özet
Objective: The aim of this study was to evaluate the thickness of the lower uterine segment (LUS) by ultrasonography in patients with and without pain who had a previous cesarean section and to determine a cut-off thickness value that can predict uterine rupture by comparing the values found. Material and Methods: A total of 100 pregnant women with previous cesarean section who presented to the emergency department with pain and 100 pregnant women without pain who were scheduled for elective cesarean section were evaluated. In both groups, endometrial wall thickness was measured by ultrasonography at presentation. Intraoperative findings were recorded according to the Qureshi scoring system. Results: An LUS thickness of 1.75 mm was considered the critical cut-off value, obtained from the ROC curve with 90% sensitivity and 90% specificity using transabdominal ultrasonography. Linear regression model analysis revealed that a full LUS thickness <1.75 mm was the only factor associated with a translucent uterine segment (C3). Conclusion: We found an increased risk of uterine rupture at an ultrasonographic thickness <1.75 mm in pregnant women with pain and previous cesarean section. Ultrasonographic niche measurement will enable appropriate obstetric care to prevent adverse maternal and fetal outcomes and will alert physicians for a planned cesarean section.
