Evaluation of the efficacy of transobturator tape surgery in the treatment of stress urinary incontinence using urodynamics and questionnaires

OBJECTIVE To measure the efficiency of transobturator tape (TOT) surgery using urodynamics and questionnaires in stress urinary incontinence. MATERIALS AND METHODS Ninety-two patients with stress and mixed urinary incontinency who underwent TOT surgery were selected for the study. We retrospectively examined the patients' urodynamics, ultrasonography, demographic characteristics, incontinency surveys, life quality scores [incontinence impact questionnaire, (IQ-7) and urinary distress inventory (UDI-6)], diagnostic findings, Q-type test, surgical records, and complications. Patients treatment adherence, life quality scores, and urodynamics were evaluated as per the findings and complications following discharge of the patients between 12 and 36 months. Patients with a surgical history as the result of incontinence were excluded from the study. RESULTS Prior to surgery, 57 (61%, 95) patients had stress urinary incontinence (SUI), and 35 (38%, 05) patients had mixed urinary incontinence (MUI). During surgery, 45 (48%, 91) patients underwent extra pelvic surgical intervention. The mean follow-up time was 22.17±7.55 months. Our subjective success rate was 91%, 3 and the objective success rate was 78%, 3. In the life quality evaluation, a statistically significant improvement was found between IIQ-7 and UDI-6 scores. Parity over 4 was an important failure reason. Two (2%, 17) patients developed vaginal erosion, 2 (2%, 17) of the patients developed temporary urine retention, and 1 (1%, 08) patient developed nova urge incontinence. CONCLUSION Our study demonstrates that TOT surgery provides high objective and subjective success and has a positive impact on life quality. The ease of application and lower complication rate makes TOT a valuable alternative for other treatment approaches in the surgical treatment of SUI.
