Purpose
Prospective evaluation of independent risk factors for failure of the retrourethral transobturator sling suspension (RTS) with special attention on sphincter function and surgical technique.
Methods
A total of 189 patients with postprostatectomy stress urinary incontinence (SUI) were treated with RTS (AdVance® sling) in a prospective clinical study with a mean follow-up of 20.8 months. Eleven patients were lost to follow-up. Uni- and multivariate analyses were performed to identify independent risk factors for RTS failure. The success rate was defined as cured (no pad use or one dry ‘security’ pad) or improved (one to two pads and pad reduction ≥50%).
Results
At a mean follow-up of 20.8 months, the overall success rate was 73.1%. Multivariate analysis revealed that weak residual function and incomplete closure of the sphincter (OR, 29.0), no elongation of the coaptive sphincter zone (OR, 26.9), no sling tunnelling (OR, 22.6) and use of resorbable sutures with a small number (≤4) of stitches (OR, 8.4) are significant predictors for RTS failure.
Conclusions
Preoperative selection of the patients with regard to residual sphincter function and a special attention on better sling fixation may increase RTS efficacy.
