Abstract

Acute anuria due to bilateral distal ureteral obstruction developed in two boys, ages 7 and 13, several days after appendectomy, without sonographic signs of hydronephrosis or hydroureters. Decompression was achieved after introduction of ureteric stents. This failed on the left side in one patient, and unilateral acute tubular necrosis (ATN) subsequently developed on that side. Although bilateral decompression was successful in the second patient, ATN had already developed on the left side. In both patients, Tc-99m MAG3 renal scintigraphy proved to be an important tool in diagnosing unilateral ATN and for evaluating the recovery from this rare complication.
