Comparative results of two techniques to treat stress urinary incontinence: synthetic transobturator and aponeurotic slings.

Introduction and hypothesis: This study aims to analyze comparatively the efficacy and safety of synthetic transobturatory and aponeurotic retropubic slings, in the treatment of stress urinary incontinence (SUI) in women.

Methods: Patients were separated in a randomized way. Twenty-one patients were submitted to the operatory correction by the transobturatory sling technique, whereas 20 patients were operated by the retropubic sling technique. All patients were submitted to complete physical exam and urodynamic test. The "T" test and the Mann-Whitney U test were applied to establish comparisons between the two groups. Patients were followed-up for 12 months.

Results: Healing rate was 90.5% (19/21) and 95% (19/20), respectively after 12 months. The transobturatory group presented lesser complications rate than the retropubic group.

Conclusions: The transobturatory and the aponeurotic slings techniques were equally effective for the treatment of SUI. The transobturatory sling has shown fewer complications and lesser surgical time than the aponeurotic sling technique.
