The overall pooled prevalence of postoperative AKI was 2.5% (95% CI, 1.8-3.1), with substantial heterogeneity (<i>I²</i> = 98.1%). Subgroup analyses showed higher AKI rates in case-control studies, small sample studies, and studies based on the AKI Network criteria. Significant risk factors for AKI included male sex (OR, 2.15; 95% CI, 1.54-3.01), pre-existing renal insufficiency (OR, 5.33; 95% CI, 1.4-20.26), hypertension (OR, 1.74; 95% CI, 1.37-2.21), hyperlipidemia (OR, 1.53; 95% CI, 1.04-2.24), and elevated body mass index (OR per unit increase, 1.05; 95% CI, 1.02-1.09). Diabetes and age were not significantly associated with AKI across the studies.</p><p><strong>Conclusions: </strong>AKI occurs in approximately in 2.5% of adults with obesity following bariatric surgery. Identifying high-risk patients based on clinical factors may help guide perioperative renal protection strategies.</p>","PeriodicalId":49361,"journal":{"name":"Videosurgery and Other Miniinvasive Techniques","volume":"21 1","pages":"13-21"},"PeriodicalIF":1.7,"publicationDate":"2026-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13123263/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147787264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
