Background: A clinical cohort study of 254 women undergoing trans-obturator surgery for stress urinary incontinence was conducted to assess the efficacy of the trans-obturator suburethral tape (TOT) after a follow-up of 1 year (251 evaluable patients) and 2 years (62 patients).
Results: Seventy-five patients had previous gynaecologic surgery. Overall cure and improvement rates were 82% at 6 and 12 months, and 90% at 24 months. The most favourable results were obtained in patients with occult incontinence and urethral hypermobility. The relative risk (RR) for failure in patients with a history of gynaecologic surgery was 3.3 (95% CI: 1.1-14.7). There were 8 cases of bladder perforation (3.1%) during the learning phase with the TOT procedure, 20 of urinary retention (7.9%) - in 1 patient the tape was released after 12 days of insertion - and 3 of tape erosion (1.2%).
Conclusion: Results are encouraging but should be substantiated on a larger series over a longer follow-up.
