A prospective multicenter European observational study of a single incision sling (Altis®): A safe and effective treatment option for women

Abstract

Introduction:Single-incision slings were introduced for female stress urinary incontinence (SUI) treatment to decrease surgery time, postoperative pain, and the amount of mesh used. Objective:This multicenter study aims to examine Altis® usage in real-world clinical practice, its effectiveness in treating SUI, patient satisfaction, quality of life, sexual function, and complication rates. Methods:Between 2015 and 2022, a prospective single-arm observational cohort study was conducted across 33 European centers involving 564 patients, investigating the clinical effectiveness of the Altis® sling. Patients were monitored for 36 months. The primary endpoint (success) was a positive impression of improvement and absence of serious/severe/Clavien Dindo (CD) ≥ III-related adverse events at 12 months. Secondary endpoints included effectiveness at 36 months, impact on quality of life, and risk factors for failure. Results:An Altis® was implanted in 564 women. At 12-months, 86.6% of patients achieved success, 97.2% endorsed the surgery, and 90.4% were satisfied with the outcomes. At 36 months, 83.0% reported significant improvement, 94.5% endorsed the surgery, and 89.9% were satisfied. Altis® demonstrated decreased daily pad usage and improved quality of life. Dyspareunia and sexual function largely remained unchanged. However, 11.3% reported pain, and there were instances of serious adverse events. Conclusion:The Altis® implant demonstrated substantial improvements in symptoms and overall quality of life for a majority of women with SUI. Potential complications such as mesh exposure, reoperation, voiding dysfunction, and urinary retention emphasize the importance of preoperative counseling. The Altis® implant is a viable option within the available surgical treatments of SUI.
