The aim of the present paper was to assess and compare the long-term efficacy and safety of single-incision mini-slings (SIMSs), except tension-free vaginal tape (TVT)-Secur, with standard midurethral slings (SMUSs) for female stress urinary incontinence through an updated systematic review and meta-analysis of randomized controlled trials (RCTs) comparing these two surgical methods. A literature review of all RCTs comparing SIMSs (Mini-Arc, Contasure-Needleless, Ophira, Tissue Fixation System and Ajust), except TVT-Secur, with SMUSs was performed. The Medline, Embase, Scopus, Web of Science and Cochrane Controlled Trial Register databases were reviewed. We retrieved 29 RCTs (including a total of 2 986 patients) that compared SIMSs, except TVT-Secur, with SMUSs. Meta-analysis of long-term results showed no significant difference in the patient-reported cure rate (odds ratio [OR] 0.67, 95% confidence interval [CI] 0.44–1.60); however, we found that SMUSs had a significantly superior objective cure rate (OR 0.68, 95% CI 0.47–0.99; P = 0.04). SIMSs were associated with a significantly shorter operation time, lower immediate postoperative pain based on a visual analogue scale score, lower intra-operative blood loss, and lower postoperative voiding dysfunction. The meta-analysis showed clear evidence of the superiority of SMUSs over SIMSs, except TVT-Secur, in terms of the objective cure rate, after long-term follow-up; however, SIMSs were superior with respect to immediate postoperative pain, intra-operative blood loss, and postoperative voiding dysfunction.
