Autotransplantation of the kidney was performed in seven adult mongrel dogs. A model of acute tubular necrosis (ATN) was developed by subjecting the kidney to warm ischemia (37°C) for 40 to 60 minutes. Serial ultrasound examinations were performed every 12 hours until the animal died or was killed. Sonographic findings were correlated with laboratory and histological data. Throughout the course of ATN, the characteristic normal echo pattern of the kidney remained unchanged in six of seven dogs. In one animal there were changes in the renal cortex, while the medullary pyramids showed no alteration from the base-line study. This contrasts with extensive abnormalities found during rejection.
