Tension-free vaginal tape obturator versus Ajust adjustable single incision sling procedure in women with urodynamic stress urinary incontinence.

OBJECTIVE

To assess the efficacy and complications of inside-out transobturator tension-free vaginal tape (TVT-O) in comparison with a single incision sling procedure (Ajust) for the treatment of urodynamic stress urinary incontinence.

STUDY DESIGN

Prospective closely matched controlled study. In total, 171 patients were included in the study: 86 women underwent the TVT-O procedure, while in other 85 cases the Ajust procedure was performed. Subjective and objective cure, improvement and failure rates, mean operative time, hospital stay and incidence of complications were assessed.

RESULTS

There was no statistically significant difference between the two groups for age, body mass index, parity, menopausal status and severity of prolapse. No major intraoperative complications occurred. There was no significant difference in the mean operative time and the duration of hospital stay between the two groups. The mean follow-up time of the study was 22.3 months (range 12-36 months). For the TVT-O group the objective cure rate was 86%, the improvement rate was 5.9% and the failure rate was 8.1%, while the subjective cure rate was 82.6%. For the Ajust group the objective cure rate was 84.7%, the improvement rate was 4.7%, 10.6% of patients showed no change in their symptoms and the subjective cure rate was 81.2%.

CONCLUSIONS

The Ajust sling procedure presents success rates, at 22 months' mean follow up, comparable to the TVT-O method. Both techniques seem to be safe and effective for the treatment of urodynamic stress urinary incontinence.
