Objective To explore the incidence and risk factors of acute kidney injury (AKI) following hepatic arterial chemoembolization inpatients with hepatocellular carcinoma (HCC) , Child class A. Methods Retrospective analysis was performed on patients with HCC, Child Class A who were admitted from January 2008 to October 2016.The inclusion criteria: (1) patients were diagnosed with pathologically confirmed hepatocellular carcinoma based on the standards of primary liver cancer diagnosis and treatment (2011 edition);(2) patients have complete laboratory parameters and imaging data within the 7 days before the TACE treatment;(3) the Child-pugh score was 5 to 6;(4) patients have no acute or chronic renalfailure before the treatment of TACE.The morbidity of AKI after TACE was investigated.Twenty-six factors such as age,sexy,contrast dose,hemoglobin were included as independent variable, so as to investigate the risk factors for postoperative AKI. Results A total of 818 patients were included in the study, including 38 experiencing postoperative AKI(4.64%). Multivariate logistic regression analysis identified elevated preoperative uric acid as the independent risk factor for postoperative AKI(OR=1.005, 95% CI 1.000 to 1.009,P=0.037), and elevated preoperative hemoglobin as the protective factor for postoperative AKI(OR=0.974, 95% CI 0.952 to 0.997,P=0.028). Conclusions AKI is not uncommon following hepatic arterial chemoembolization inpatients with HCC, Child Class A, and is correlated with elevated uric acid and anemia. Preoperative risk assessment and anemia correction might be effective for reducing the incidence of AKI following hepatic arterial chemoembolization.
