AKI was defined and classified by AKI Network (AKIN) Classification\/Staging System. The incidence, mortality, and risk factors of postoperative AKI were investigated. Receiver operating characteristic curve analysis was conducted to evaluate the ability of markers in predicting AKI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The incidence of postoperative AKI was 4.4% (25 cases). The mean onset of postoperative AKI was 8.0 \u00b1 5.3 days and recovered after 7.0 \u00b1 4.2 days after the occurrence of AKI. Of 25 patients with AKI, 6 patients (24.0%) died within 1 year after surgery. The independent risk factors for postoperative AKI are the estimated blood loss (EBL) (odds ratio (OR) 1.64; 95% confidence interval (CI) 1.33\u20132.58; p &lt; 0.01) and postoperative level of albumin (OR 1.77; 95% CI 1.52\u20132.74; p &lt; 0.01). The cutoff value of the serum albumin was &lt;2.8 g\/dL with a sensitivity of 88.0% and a specificity of 77.1%. The cutoff value of EBL was &lt;766.5 mL with a sensitivity of 84.0% and a specificity of 66.3%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Postoperative AKI after hip fractures had low incidences (4.4%) but high mortality (24.0%).
