Treatment of female stress urinary incontinence with transobturator suburetral band compared with single incision sling: 7-year follow-up

Objetives: Compare the efficacy and post-surgical complications of single-incision sling (SIS) and transobturator band (TO) for the treatment of stress urinary incontinence (SUI) over 7 years’ follow up. Methods: This is a prospective observational study that included 289 women with SUI who went under surgical treatment, either TO (109) or SIS (180). Patients were evaluated pre- and postoperatively through anamnesis, physical examination and ultrasound. Epidemiological information, complications and surgical time were recorded. The primary outcomes were total continence, objective and subjective cure rates at 7-year follow-up. Statistics: T-Student or U-Mann-Whitney for quantitative variables, Chi-Square for qualitative variables. Results: The groups were similar regarding demographic and medical history parameters, except for age and arterial hypertension, which were higher in TO group, and that SIS patients were more physically active tan TO patients. The TO band compared to SIS associated with increased frequency repair of pelvic organ prolapse. Depending on the type of urinary incontinence, pure SUI was more frequent in SIS and mixed in TO. The duration of the surgery was shorter with SIS. During the 7-year follow up there were no differences in the objective cure, subjective cure and complication rates. Conclusion: After 7-years follow-up, no significant differences were found with regard to subjective and objective outcomes, and post-surgery complication rates between the single incisión sling and the transobturator band.
