Abstract：Objective To investigate the clinical characteristics and prognostic risk factors of elderly patients with acute kidney injury (AKI).Methods From August 2012 through July 2016,we enrolled 206 patients with AKI.The patients were divided into the elderly group (≥60 years old,n =97) and the non-elderly group (＜60 years old,n =109) by age,and patients in the elderly group were further assigned to renal function recovery group and renal function non-recovery group according to the prognosis of the patients.The data of age,sex,underlying diseases (hypertension,coronary heart disease and diabetes) and AKI stage were documented.The glomerular filtration rate (GFR) was calculated,and the prognosis and risk factors were observed.Results The age,sex,underlying diseases,AKI stage Ⅰ,AKI stage Ⅲ and GFR differed significantly between the two groups(P ＜0.05).In the elderly group,the number of those with and without renal function recovery was 51 (52.6％) and 46 (47.4％)respectively at discharge from hospital.Compared with renal function non-recovery group,there were significant differences in AKI stage Ⅰ,AKI stage Ⅲ,GFR ≤60 ml/ (min · 1.73m2) at diagnosis,hypoproteinemia,and renal replacement therapy (RRT) in renal function recovery group.Multivariate logistic regression analysis showed that hypoproteinemia,AKI stage Ⅲ and RRT were independent risk factors for the prognosis of elderly patients with AKI.Conclusion Hypoproteinemia,RRT and AKI stage Ⅲ were closely associated with the prognosis of elderly AKI patients.
