Correlation between color doppler ultrasonographic indices and serum creatinine level before and after renal transplantation

The measurement of color Doppler ultrasonographic indices, such as resistive index (RI) can help in the evaluation of a transplanted kidney. This study sought to examine correlation between color Doppler ultrasonographic indices and serum creatinine levels before and after renal transplantation.

A total of 100 patients with end stage renal disease undergoing kidney transplantation were enrolled in this study. Serum creatinine levels was measured before transplantation, on day 5 and at the end of the third month after transplantation. Central and peripheral RI values of the transplanted kidney were also documented on day 5 an month 3 posttransplantation.

Creatinine level at the end of third month had positive correlation with central (r=0.27 and p=0.007) and peripheral RI values (r=0.26 and p=0.009) in day 5 after transplantation. There was also a significant positive correlation between the serum level of creatinine at the end of the third month and central (r=0.50 and p

Both peripheral and central RI values on day 5 can be used for predicting malfunctioning transplanted kidney.
