Patients were categorized into non-AKI, AKI stage 1\u20132, and AKI stage 3 groups. Data were analyzed using chi-square, Fisher\u2019s exact, Kruskal-Wallis tests, and logistic regression to compare groups and determine independent risk factors for AKI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      AKI occurred in 97 patients, yielding an overall prevalence of 3.47%. The incidence was highest among patients undergoing bone tumor surgery (11.36%) and lowest in those undergoing spinal surgery (2.46%). Patients in the AKI stage 3 group had a significantly higher proportion of bone tumor surgeries and longer hospital stays compared to other groups (\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.001). Multivariate analysis identified bone tumor surgery, preoperative proteinuria, elevated urea, decreased hemoglobin, and the use of proton pump inhibitors (PPIs) and non-steroidal anti-inflammatory drugs (NSAIDs) as independent risk factors for AKI.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>There is a significant risk of AKI following orthopedic surgery, particularly in patients undergoing bone tumor procedures.
