Single-incision mini-sling and trans-obturator sling for stress urinary incontinence: A 5-year comparison

Objective: The aim of our study was to compare objective and subjective outcomes in women with stress urinary incontinence (SUI) submitted to either trans-obturator sling (TVT-ABBREVO (R)) or single incision mini-sling (SIMS-ALTIS (R)) at 5-year follow up. Study design: A monocentric, retrospective study including women with isolated SUI and with concomitant proved urodynamic stress incontinence (USI), treated with an TVT-ABBREVO (R) or SIMS-ALTIS (R). At 60-month follow up each woman was assessed subjectively, with two validated questionnaires (UDI-6 and ICQI-SF), and objectively with a cough stress test. Adverse events were collected. Results: Forty-two patients were evaluated in the ABBREVO (R) group and 58 in the ALTIS (R) group. No significant difference was found in subjective (88.1% vs 89.7%, p = 0.806) and objective (81.0% vs 86.2%, p = 0.479) cure rates between the two groups. Subjectively, improvement in urinary distress after surgery resulted statistically significant in both groups compared to baseline (p < 0.001). Long-term post-operative complications rate (i.e. de novo OAB and sling exposure) was similar in the two groups. They were, in fact, mainly classified as Dindo II grade and conservatively managed (i.e. antimuscarinics or beta(3) agonists for de novo OAB). Conclusion: This comparative study did not reveal significant difference between single-incision (ALTIS (R)) and trans-obturator (TVT-ABBREVO (R)) slings in terms of efficacy and morbidity at 5-year follow up.
