Autologous Slings in Female Stress Urinary Incontinence Treatment: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

INTRODUCTION AND HYPOTHESIS: The aim of this study is to evaluate the efficacy and safety of autologous fascial slings (AFS) compared with other surgical methods for female stress urinary incontinence (SUI) treatment.

METHODS: The search was performed on studies published before September 2023 to identify articles assessing the effectiveness and safety of AFS compared with other surgical methods in female SUI. Inclusion criteria were randomized controlled trials (RCTs) and adult women with SUI. Exclusion criteria were other urinary incontinence types, combined pharmacological treatment, pregnancy, and lactation. This systematic review was conducted according to the Population, Intervention, Comparison, and Outcome framework, Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 checklist, and was registered in the Prospective Register of Systematic Reviews.

RESULTS: Twenty RCTs were included in the systematic review and 10 RCTs in the meta-analysis. Comparison between AFS and synthetic midurethral slings (SMUS) did not show any statistically significant differences in the cure rate, frequency of urinary retention, or self-catheterization. SMUS showed more long-term postoperative complications (RR = 0.12, 95% CI: 0.03 to 0.50, p = 0.004), AFS had more in de novo urgency cases: (RR = 2.84, 95% CI: 1.13 to 7.10, p = 0.03). Operation time of SMUS was lower: (RR = 2.87, 95% CI: 2.56 to 3.19, p < 0.00001, I2  = 97%). SMUS showed significantly lower hospital stay duration: (RR = 1.92, 95% CI: 1.44 to 2.41, p < 0.00001).

CONCLUSIONS: In this systematic review and meta-analysis, autologous slings demonstrated the same efficacy in comparison with SMUS in the management of SUI in women. AFS showed lower incidence of long-term postoperative complications. SMUS demonstrated lower operation time, hospital stay and de novo urgency.
