Abstract:
Objective To evaluate the accuracy of color Doppler in predicting acute kidney injury ( AKI) . Methods Patients of both sexes with AKI risk factors not diagnosed with AKI, aged ≥18 yr, were enrolled in this study. Within 1 h after inclusion, the renal blood flow ( RBF) grade was monitored u-sing color Doppler, and renal resistive index ( RRI) value of renal interlobar artery was monitored at the level of renal interlobar or arcuate arteries, and corrected RRI value was calculated. The development of AKI was recorded within 24 h through measuring serum creatinine and urine volume, and the receiver oper-ating characteristic curve was plotted. Results Thirty-eight patients were included in non-AKI group and 40 ones in AKI group. Compared with non-AKI group, RBF grade was significantly decreased, RRI value was increased ( P<0. 05) , and no significant change was found in the corrected RRI value in AKI group ( P>0. 05) . The area under the curve of RBF grade and RRI value in predicting AKI occurred within 24 h and 95％ confidence interval were 0. 659 ( 0. 561-0. 747) and 0. 669 ( 0. 572-0. 756) , respectively. Con-clusion Color Doppler has a certain value in predicting AKI within 24 h.
