Outcomes following repeat mid urethral synthetic sling after failure of the initial sling procedure: rediscovery of the tension-free vaginal tape procedure.J Urol. 2007 Oct; 178(4 Pt 1):1370-4; discussion 1374.JU
We evaluated outcomes of the repeat mid urethral sling to treat recurrent or persistent stress urinary incontinence after failure of an initial mid urethral sling.
MATERIALS AND METHODS
We retrospectively analyzed data on patients who underwent the repeat mid urethral sling procedure due to persistent or recurrent stress urinary incontinence. Repeat slings were placed without removal of the previous sling. All patients were followed at least 1 year after the second mid urethral sling.
Of the 31 female patients with a repeat mid urethral sling 29 were followed, including 13 with a retropubic and 16 with a transobturator sling. For the first mid urethral sling 17 patients received a retropubic sling (tension-free vaginal tape) and 12 received a transobturator sling (6 inside out and 6 outside in procedures). Cure and improvement rates irrespective of the approach were 75.9% (22 of 29 patients) and 6.9% (2 of 29), respectively. Cure rates for the retropubic and transobturator slings were 92.3% (12 of 13 patients) and 62.5% (10 of 16), respectively, a difference that did not quite attain statistical significance (p = 0.089).
The repeat mid urethral sling for persistent or recurrent stress urinary incontinence has a lower cure rate than the initial sling. However, the retropubic approach tends to have a higher cure rate than the transobturator approach in repeat sling cases.
