Abstract：Objective To analyze the reliability of renal resistance index (RRI) in diagnosis of acute kidney injury (AKI) after acute Stanford type A aortic dissection surgery.Methods A prospective study was conducted in 61 patients with acute Stanford type A aortic dissection who had surgical operation from March to August 2016 in Beijing Anzhen Hospital,Capital Medical University.RRI was measured by ultrasonic examination.AKI was diagnosed according to the diagnostic criteria of the Acute Renal Injury Working Network Group(AKIN) and severity of the disease was divided into stage 1,2,3 based on serum creatinine and urine volume.Sensitivity,specificity,positive predictive value,negative predictive value,missed diagnosis rate,misdiagnosis rate and diagnostic coincidence rate of RRI in diagnosis of AKI were analyzed by the receiver operating characteristic curve.Correlation between RRI and severity of AKI was analyzed by Pearson test.Results Sensitivity,specificity,positive predictive value,negative predictive value,missed diagnosis rate,misdiagnosis rate and diagnostic coincidence rate of RRI in diagnosis of AKI were 79.5％,81.8％,88.6％,69.2％,20.5％,18.2％ and 80.0％,respectively.RRI increased with AKI severity and there was a positive correlation between them(r =0.674,P ＜0.05).Conclusions RRI shows high consistency and coincidence compared with AKIN criteria in diagnosis of AKI.RRI is positive correlated with severity of AKI.
