Comparison of Two Single-Incision Mini-Slings for the Treatment of Incontinence

Abstract

Introduction: This study aimed to compare the safety and efficacy of 2 single-incision mini-sling (SIMS) systems with different designs of anchoring mechanism. Methods: The records of patients who have been operated for the treatment of female stress urinary incontinence (SUI) with 2 different SIMS systems were retrospectively evaluated. Patient characteristics, physical examination results, and quality of life (QoL) questionnaires were used to evaluate the patients. Primary efficacy endpoints were the cure and failure rates. Secondary efficacy endpoints were complications and differences in QoL questionnaires. Results: Eighty-Three patients from group 1 (Ophira SIMS system) and 77 patients from group 2 (Gallini SIMS system) were evaluated. There was no significant difference between the 2 groups regarding patient characteristics. The objective cure rates were found to be 83.1 and 79.2% in group 1 and group 2, respectively (p = 0.09). Mesh-related complications, such as anchor displacement, bladder erosion, vaginal erosion, and groin pain, were more common in group 1. No severe complications were observed. For both groups, a significant improvement in all scores of QoL questionnaires was observed after surgery; however, the differences between 2 groups were not significant. Conclusions: The present study showed that the treatment of female SUI with 2 different SIMS systems had similar efficacy, complication rates, and scores in QoL questionnaires.
