amyloid nephrosis  renal amyloidosis.

lipid nephrosis  minimal change disease.

lower nephron nephrosis  renal insufficiency leading to uremia, due to necrosis of the lower nephron cells, blocking the tubular lumens of this region; seen after severe injuries, especially crushing injury to muscles (crush syndrome) .

amyloid nephrosis

chronic nephrosis with amyloid deposition in glomerular capillaries, in basement membranes of tubules and eventually around tubules.

biliary nephrosis

the renal component of acute hepatic failure characterized by oliguria and azotemia.

infectious avian nephrosis

see infectious bursal disease.

lipid nephrosis

nephrosis marked by edema, albuminuria, and changes in the protein and lipids of the blood and accumulation of globules of cholesterol esters in the tubular epithelium of the kidney.

lower nephron nephrosis

now called acute renal tubular necrosis where tubular degeneration occurs as a consequence of ischemia and nephrotoxins. Complete urinary outflow obstruction follows, resulting in acute renal failure. Also seen after severe injuries, especially crushing injury to muscles. See also crush syndrome.

mycotic nephrosis

caused by ingested toxins of Aspergillus ochraceus, Penicillium viridicatum. Characterized by enlarged, terminally fibrosed kidneys, polyuria and polydipsia. See also mycotoxicosis.
