Aim:To compare the classical double-layer uterine closure to a double-layer purse-string uterine closure (Turan technique) in cesarean section regarding short- and long-term results.Methods:Patients were randomized into either the double-layer purse-string uterine closure arm (study group, 84 patients) or the classical double-layer uterine closure arm (control group, 84 patients). For short-term comparison, a detailed transvaginal ultrasound examination was planned in all patients 6 weeks after the operation and a wedge-shaped defect in the uterine incision scar was accepted as uterine scar defect and recorded. For the long-term comparison, subsequent pregnancies of these patients were followed up for any complication.Results:The number of patients with ultrasonographically visible uterine scar defect was 12 (23.5% of all scar defects) in the study group whereas it was 39 (76.5% of all scar defects) in the control group (P < 0.001, χ2 = 15.42). Demographic data, operation time, hospitalization time, preoperative and postoperative hemoglobin values were not significantly different between the groups. During the 2-year of the follow-up period, five patients in the study group and six patients in the control group became pregnant again. No complication during their pregnancies and second cesarean operation were encountered.Conclusion:With the Turan technique, the uterine incision length becomes shorter, and the frequency of uterine scar defect is lower regarding short-term results. More data is needed for long-term results. ClinicalTrials.gov NCT01287611
