✦ Synopsis

Forty-five kidney transplant recipients with delayed onset of diuresis due to acute tubular necrosis (ATN) were examined with duplex ultrasonography (DU). Resistive index (RI) was measured on the 4th post-transplant day. Eleven grafts (24%) developed acute rejection. Mean RI prior to rejection of the 4th postoperative day in these grafts was 0.97 and in the 34 grafts which did not develop rejection mean RI was 0.82. There were 2/26 rejections (8%) in the group of grafts with an initial RI below 0.9 and 9/19 rejections (47%) in the group of grafts with RI of 0.9 or above on the 4th post-transplant day. Six months postoperatively there were 2/26 nonfunctioning grafts in the group with lower initial RI values (less than 0.9) and 6/19 nonfunctioning grafts in the group with higher indices (greater than or equal to 0.9). In nonfunctioning grafts a high initial RI (greater than or equal to 0.9) indicates that these grafts will be prone to developing acute rejection.
