Abstract

The prospective comparison of the clinical effectiveness and the complication rate of retropubic (IVS-02) and transobturator (IVS-04) midurethral slings in the treatment of female stress urinary incontinence. Objectives: The purpose of this study was the prospective comparison of clinical efficacy and safety of retropubic (IVS-02) and transobturator suburethral tape techniques (IVS-04) in the treatment of female stress urinary incontinence. Material and methods: From January 2003 to June 2004, 145 patients with uro-dynamically proven stress urinary incontinence underwent surgical treatment (IVS-02 or IVS-04). During pretreatment work-up, all patients had undergone full clinical and urodynamic evaluation. Patients with mixed, urge incontinence and the advanced urogenital prolapsed (POPQ scale >2) were excluded from the study. Results: Patients clinical characteristics and urodynamic parameters were comparable between the analyzed groups. At one year follow-up, 122 patients (61 in each group) were evaluated in terms of clinical efficacy of the procedure. The total cure (78,7% in IVS-02 vs 70,5% in IVS-04), the improvement (14,7% vs 21,3%) and the failure rates (6,6% vs 8,2%) were similar in both analyzed groups, chi2=0,58; (p=0,75). Conclusions: The transobturator route for the treatment of stress urinary incontinence appears to be as effective as the retropubic one at one year follow-up. Moreover, the shorter operation time and no need to perform cystoscopy during the surgery make the transoburator
