Objective: Acute kidney injury (AKI) is a critical clinical event after hip fracture operation. Our study aimed to determine risk factors and the incidence of postoperative AKI among patients >= 85 years who underwent hip fracture surgery and were admitted to an intensive care unit (ICU). Methods: The medical data of all patients >= 85 years that underwent hip fracture surgery were retrospectively analyzed. Results: During the study period, 164 patients were analyzed and had a mean age of 89.6 +/- 3.5 years, including 122 females (74.4%). The incidence of postoperative AKI was 26.8% and 26.2% were Stage I. Preoperative hypertension, usage of diuretics, preoperative lymphopenia, low heart rate upon ICU admission, high sequential organ failure assessment scores on postoperative 1st, 2nd, and 3rd days and low MAP on the postoperative 2nd day were determined independent risk factors about AKI after operation. Conclusion: The incidence of AKI was 26.8%. Preoperative hypertension, use of diuretics, preoperative lymphopenia, low heart rate at intensive care unit admission, high sequential organ failure assessment scores on postoperative 1st, 2nd, and 3rd days, and low MAP on postoperative 2nd day were independent risk factors about AKI after hip fracture operations in the oldest-old patients.
