We included studies comparing vacuum suction RIRS with non-vacuum RIRS. Following the PRISMA guidelines, we performed a meta-analysis of the selected studies. Inclusion criteria were randomized controlled trials (RCTs), case-control studies, and retrospective studies evaluating the efficacy of these techniques. Key outcomes analyzed included operative time, hospitalization duration, stone-free rates, and complication rates. Statistical analyses were conducted using mean differences (MD) for continuous variables and odds ratios (OR) for dichotomous outcomes, with corresponding 95% confidence intervals (CI).<h4>Results</h4>Sixteen studies (6 RCTs, 1 case-control study, and 9 retrospective studies) involving a total of 2029 patients were included. Meta-analysis revealed that the vacuum suction technique significantly reduced operative time (MD = - 14.45 min, 95% CI [- 18.45; - 10.44], P < 0.00001) and hospital stay (MD = - 0.54 days, 95% CI [- 0.80; - 0.28], P < 0.00001). In addition, patients in the vacuum suction group had a higher stone-free rate (OR = 3.57, 95% CI [2.57; 4.95], P < 0.00001) and lower complication rates, particularly in reducing postoperative fever.<h4>Conclusion</h4>The application of the vacuum suction technique in RIRS significantly improves clinical outcomes by reducing operative time and hospitalization duration, enhancing stone-free rates, and lowering postoperative complication rates. This technique demonstrates a clear clinical advantage over non-vacuum RIRS and should be considered a preferred option for the management of upper urinary tract stones."],"journal":["International urology and nephrology"],"pagination":["1051-1062"],"full_dataset_link":["https://www.ebi.ac.uk/biostudies/studies/S-EPMC11903590"],"repository":["biostudies-literature"],"pubmed_title":["Comparison of suction technique and non-suction technique in retrograde intrarenal stone surgery: a systematic review and meta-analysis."],"pmcid":["PMC11903590"],"pubmed_authors":["Liu Y","Chen P","Jin X","Chen J","Mi G","Jian Z","Wang K"],"additional_accession":[]},"is_claimable":false,"name":"Comparison of suction technique and non-suction technique in retrograde intrarenal stone surgery: a systematic review and meta-analysis.","description":"<h4>Objective</h4>To evaluate the clinical efficacy of retrograde intrarenal stone surgery (RIRS) using the vacuum suction technique for the treatment of upper urinary calculi.<h4>Methods</h4>A comprehensive literature search was conducted across multiple databases, including PubMed, Embase, Sino Med, CNKI, WANFANG DATA, and Cochrane.
