Comparison of Surgical Outcomes of Autologous Mid-Urethral Fascia Slings and Retropubic Mid-Urethral Slings for Women Undergoing a Primary Surgery for Stress Urinary Incontinence: A Systematic Review and Meta-Analysis.

Abstract

Aim: Current guidelines on surgical treatment of stress urinary incontinence (SUI) recommend an informed decision making process between the physicians and patients reviewing all available surgical options with and without mesh. However, there is a lack of synthesized clinical evidence on some of the comparisons that can feed into patient counseling processes. The aim of this study was to review the available studies comparing clinical outcomes of an autologous fascial sling (AFS) and a retropubic (RP) synthetic sling for women undergoing a primary surgery for SUI.

Methods: We conducted a literature search from 1990 to 2024 following international guidelines. We have included studies reporting on comparative outcomes of AFS and RP synthetic sling surgeries as a primary procedure.

Results: Three randomized studies were included with follow-up durations ranging from 24 months to 10 years. The mean percentage change in symptom scores ranged from 27.7% to 44.9%, with no significant difference between the two sling types. There was no difference between groups with regard to objective cure rates, subjective cure rates and length of hospital stay between AFS and RP slings. AFS surgeries had longer operative times. There were concerns about bias, particularly related to allocation, blinding, and missing outcome data.

Conclusion: Overall, both types of slings had similar cure rates but AFSs were associated with longer operative times. The study highlights the need for more research on the comparative effectiveness of AFS and synthetic slings for SUI surgery to guide decision-making for SUI surgical treatments.
