entering the ICU. All patients received bedside ultrasound examination. The general clinical data, renal function indexes, renal
resistive index (RRI) and pulsatility index (PI) at different time points were compared between two groups. Meanwhile, the
correlations among RRI, PI and renal function indexes were analyzed. The receiver operating characteristic (ROC) curve was
Ⅱ
used to evaluate the diagnostic value of RRI and PI in AKI. Results The AKI group had higher APACHE score, SOFA score
and 28-day mortality rate than the non-AKI group (P<). AKI group had significantly higher serum CysC and β2-MG levels
than the non-AKI group on the 1st, 3rd, 5th and 7th day (P<). Besides, there were significant differences in serum β2-MG
levels in AKI group at different time points (P<). On the first day after entering the ICU, no significant differences were
found in RRI and PI between the 2 groups (P>). However, on the 3rd, 5th, and 7th day after entering the ICU, AKI group
