Effectiveness of TVT and TVT-O Operations in the Treatment of Female SUI

Objectives: to compare TVT (tension-free vaginal tape) and TVT-O (tension-free vaginal tape obturator from inside to outside) for the female surgical treatment of stress urinary incontinence: results, complications, effectiveness after 1 year. Material and methods: Prospective randomized study. Follow up period - 12 months. 114 patients were operated using TVT operation and 280 patients - TVT-O operation. There was no significant difference between groups for age, BMI (body mass index), parity, menopausal status and prolapse (no patients had cystocele greater than stage II). Rezsults: Mean operative time was significantly shorter in the TVT-O group (18 ± 4,6 min.) compared with the TVT group (27 ± 7,1 min.). There was no differences in the effectiveness of both procedures: TVT - 94,6% and TVT-O - 94,4% after one year. Hospital stay was statisticaly significantly shorter in TVT-O group (1,2 ± 0,5 days) than in TVT group (4,0 ± 1,6 days). Significantly less complications was in TVT-O group. Conclusion: TVT and TVT-O operations are equally effective for the surgical treatment of female stress urinary incontinence. TVT-O had a shorter operation time and lower complications rate.
