Summary:To investigate the relationship between the resistance index (RI) of the renal artery and serum creatinine (Cr) level in patients early (within one month) after renal transplantation. A total of 123 patients receiving renal transplantation underwent examinations by color Doppler ultrasound for measurement of the RI of the renal artery within one month after the operation. According to the results of RI measurement, the patients were divided into RI≥0.75 and RI<0.75 groups for analyzing the correlation between RI and serum Cr level measured at the same time points. The RI and Cr levels in patients with RI≥0.75 showed a significant positive correlation (P<0.05), whereas they showed an inverse correlation in patients with RI<0.75 (P<0.05). The patients with RI≥0.75 had significantly lower RI of the renal artery and Cr level than those with RI≥0.75. RI is significantly correlated to Cr, and may serve as an indicator for predicting renal graft function after transplantation.
