The tension-free vaginal tape procedure: correction of stress incontinence with minimal alteration in proximal urethral mobility

Abstract

Objectives: To prospectively assess the degree of urethral hypermobility in the preoperative and postoperative periods after the tension-free vaginal tape (TVT) procedure and correlate our findings with surgical outcome.

Methods: Twenty patients with stress incontinence underwent the TVT procedure. A Q-tip test was performed before the procedure and at the 3-week postoperative follow-up visit. Cure was defined as the absence of the subjective complaint of urine leakage and the absence of stress incontinence on stress testing at cystometric capacity.

Results: Seventeen patients (85%) were cured by the TVT procedure, 2 patients (10%) were improved, and 1 patient (5%) was unchanged. The mean preoperative and postoperative Q-tip values were 42.75 degrees and 31.75 degrees, respectively. Twelve patients had a Q-tip test result of 30 degrees or greater after surgery and 11 (92%) of these 12 patients were cured by the procedure.

Conclusions: On the basis of these results, we propose that the cure of stress incontinence does not require the correction of proximal urethral hypermobility.
