In this picture notice how the tubular epithelial cells have very eosinophilic cytoplasm and have lost their nuclei.

The right kidney weighed 270g, the left kidney 280g. Capsules stripped easily to reveal a granular surface. Cut surfaces of both kidneys showed loss of normal corticomedullary distinction, and histology revealed that acute tubular necrosis was present in both kidneys (see picture). The renal pelves and ureters were normal. The bladder had a trabeculated appearance, and no prostate tissue could be found.
