Tension-free vaginal tape evaluated using patient self-reports and urodynamic testing--a two-year follow-up.

OBJECTIVE

Urinary incontinence entails both reduced quality of life for many women and considerable public expense. Compared with other methods aimed at alleviating incontinence, tension-free vaginal tape (TVT) is minimally invasive, can be performed under local anaesthesia and results in less morbidity and shorter hospitalization. The present study was carried out to evaluate early and late complications and as a 2-year follow-up after surgery.

MATERIAL AND

METHODS

In 1996-98, 75 women underwent TVT sling plasty; mean time for surgery was 39 min and for hospitalization 24 h. The procedure caused bladder perforation in 3 women, but this was detected by cystoscopy and immediately corrected. Postoperative retention occurred in 9 patients but was transient.

RESULTS

After surgery 80% were cured, 9% showed improvement and 11% were failures. Two women exhibited vaginal erosion, and one of these had previously undergone radiation therapy. One sling caused obstruction and had to be cut. Improvements included less impact on social and physical activities and mental status and significant reduction of voiding frequency, leakage episodes and pad use.

CONCLUSIONS

The TVT technique seems to provide results comparable with those obtained with Burch colposuspension, but it entails less risk of obstruction than previous slings techniques because it causes no compression of the urethra. TVT is effective in women with genuine stress incontinence due to urethral hypermobility and in elderly women with sphincter incompetence, although the outcome is better in the former.
