Effectiveness and complications of TVT and TVT-O operations in the treatment of female stress urinary incontinence

Abstract

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. Out of 394 patients, 114 were operated using TVT operation and 280 patients – TVT-O operation. There was no significant difference between groups concerning the age, BMI (body mass index), parity, menopausal status and prolapse (no patients had cystocele greater than stage II). Results: 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 statistically significantly shorter in TVT-O group (1.2 ± 0.5 days) than in TVT group (4.0 ± 1.6 days). Significantly less complication were 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 a lower complication rate.
