- hypoxic n. acute oliguric renal failure following hemorrhage, burns, shock, or other causes of hypovolemia and reduced renal blood flow; frequently associated with patchy tubular necrosis, tubulorrhexis, and distal tubular casts of hemoglobin.
- lipoid n. idiopathic nephrotic syndrome occurring most commonly in children, in which glomeruli show minimal changes with no thickening of the basement membranes, fat vacuoles in the tubular epithelium, and fusion of glomerular foot processes. SYN: minimal-change disease, nil disease.
- osmotic n. swelling of renal tubular epithelium associated with glomerular filtration of sugars and dextrose; the swelling is due to formation of cytoplasmic vesicles by pinocytosis, and is reversible, probably with no dysfunction, when produced by glucose or mannitol.
- toxic n. acute oliguric renal failure due to chemical poisons, septicemia, or bacterial toxemia; frequently associated with extensive necrosis of proximal convoluted tubules.
