[Deferred adjustment of the tension of tension-free vaginal tape (TVT) after surgical repair of stress urinary incontinence in women].
BACKGROUND
Urinary retention is a frequent complication of repair of female urinary incontinence treated by tension-free vaginal tape (TVT). The authors report a modification of the original technique designed to decrease the risk of postoperative dysuria and retention.


METHODS
One hundred and twenty four patients with pure stress urinary incontinence were treated by TVT. In 74 patients (group 1), the TVT was placed according to the original Swedish technique. In 50 patients (group 2), no tension was applied to the suprapubic extremities of the TVT during the operation, but they were preserved and buried in an antiseptic dressing. On the day after the operation, traction was applied to the suprapubic TVT in the case of persistent incontinence. The immediate postoperative results and the results at 3 months, in terms of continence and urethral obstruction, were compared.


RESULTS
Perfect continence was obtained in 84 +/- 6.5% and 94 +/- 4.2% of patients in groups 1 and 2, respectively (p = 0.08). Acute urinary retention (15% vs 2%, p < 0.03) and post-voiding residual urine > 50 cc (38% vs 10% on D1 and 14% vs 2% at 3 months) were more frequent in group 1. At 3 months, the reduction in maximum and mean flow rate was lower in group 2 (p < 0.03). In group 2, deferred traction of the TVT was necessary in 20% of cases, without causing any major infectious complications or pain.


CONCLUSIONS
Deferred traction of TVT appears to decrease the rate of dysuria and urinary retention following repair of female urinary incontinence by tension-free vaginal tape (TVT). This technical modification does not affect the results on continence, which appears to be at least as satisfactory. This technical variant appears to be associated with a low morbidity.
