This study aim was to compare the efficacy of transobturator tape (TOT) as a new sling procedure, and Burch colposuspension as the gold standard surgical technique, in the treatment of stress urinary incontinence (SUI). This prospective randomised clinical trial was conducted on 62 women with SUI diagnosed with urodynamic test in Vali-e-Asr Hospital, Tehran, Iran. Patients were allocated into two surgery groups, randomly; TOT and Burch (31 patients in each group). After treatment, they were followed-up for long-term outcome. The average duration of follow-up was 22 and 28 months in the TOT and Burch group, respectively. Operation duration and hospital stay in the TOT group was significantly less than the Burch group (p=0.001). The rate of complete cure, improvement and failure in the TOT group was 90.3%, 9.7% and 0%, respectively, as well as 74.2%, 19.4% and 6.5% in the Burch group. In the TOT group, 90.3% of patients were very satisfied, 6.5% moderately satisfied and 3.2% were less satisfied; none of them were unsatisfied. It is concluded that the TOT procedure is a safe and effective option with less operation time and shorter in-hospital stay for SUI treatment.
