Aim: In this retrospective study, we aimed to evaluate the surgical results, complications and patient satisfaction of the transobturator tape (TOT) operation in patients with stress urinary incontinence (SUI). Method: Incontinence type and duration, demographic information, menopause status, operation time , additional surgeries, preoperative and postoperative daily pad amount, Q type and stress test results, amount of residual urine after voiding, quality of life questionnaire Urinary Distress Inventory- 6 and Incontinence Impact Questionnaire-7 (UDI-6 and IIQ-7) results, intraoperative and postoperative complications of 156 patients were recorded. The success of the operation was evaluated in 3 groups as complete recovery, partial recovery and failure. Results: Complete or partial recovery was achieved in 146 patients (93.58%) after TOT operation. Success of operation was considered as failure in 10 (6.41%) patients. Complications were observed in 20 patients. These were bleeding more than 200 ml in 2 (1.28%), vaginal perforation in 2 (1.28%), de novo urge incontinence in 6 (3.84%), perineal pain in 2 (1.28%), dyspareunia in 2 (1.28%), mesh erosion in 4 (2.56%), urinary difficulty in 1 (0.64%), and bladder perforation in 1 (0.64%) patient. Conclusion: TOT procedure can be preferred as the surgical treatment of stress urinary incontinence, with high success and low complication rates, in line with the literature.
