After de-duplication, two independent reviewers independently checked the articles in two phases (title-abstract and full-text), and a third reviewer adjudicated any conflicts. Patient demographics, diagnostic procedures, and details of kidney involvement were extracted from the included studies. Risk of bias analysis was done using the Joanna Briggs Institute critical appraisal tool. A random effects model estimated the pooled rates for AKI, oliguria, and the need for dialysis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Of the 5913 retrieved articles, 48 met the eligibility criteria.
