The value of the resistive index (RI) obtained by echo color doppler evaluation of the transplanted kidney is still not well established. Many authors consider the RI to be nonspecific sign of rejection, acute tubular necrosis, or urinary tract obstruction, but its specificity remains low. In this paper, we report our experience with RI determinations in 34 consecutive kidney transplants at different times namely: perioperatively, at 24 hours, at 3 days, at 6 and at 9 days posttransplant. In all patients intraoperative RI was normal. RI increased significantly after transplantation in 10 patients who eventually developed a complication: delayed function, acute rejection, and spontaneous kidney ruptures. This increment from the baseline value was already significant at 24 hours after the kidney transplant, indicating a possible posttransplant complication (0.62 (plus or minus) 0.07 vs 0.76 (plus or minus) 0.04; P = .0004). We conclude that the value of RI in the early posttransplant phase should be considered an important aid for the early diagnosis of posttransplant complications. (copyright) 2005 by Elsevier Inc.
