[Transvaginal ultrasound and voiding disorders after TVT procedure]

This study was carried out to evaluate the ultrasonographic findings on patients with voiding disorders after the tension-free vaginal tape procedure (TVT).

Fifty-four women had ultrasonographic evaluation 3 months after TVT procedure. The prolene tape position was evaluated with a complete sagittal view and the width of the tape and the distance between the bladder neck and the tape were measured. In the same time, patients completely cured by TVT (group 1), postoperative dysuria (group 2), de novo urge incontinence (group 3) and ineffective treatment were evaluated with a self-questionnaire and physical examination. Statistical analysis was performed using ANOVA test.

The distance between the tape and the bladder neck shows a significant difference between group 1 and 2 (13.2 mm compared to 7.6 mm) and between group 1 and 3 (13.2 mm compared to 17.7 mm). The width of the tape is significantly different between group 1 and 2 (8.8 mm compared to 6.6 mm) and between group 1 and 3 (8.8 mm compared to 6.5 mm). The distance between the tape and the bladder neck in group 2, compared with group 3, is significantly shorter (7.6 mm compared to 17.7 mm). There is no difference between the width of the tape between groups 2 and 3 (6.6 mm compared to 6.5 mm).

These results show a correlation between voiding disorders after TVT procedure and transvaginal ultrasonographic measurement of the distance between the prolene tape and the bladder neck.
