Re: CHRONIC PYELONEPHRITIS
drspleen - 03-21-11 18:44 Early stages of chronic pyelonephritis are characterized by interstitial inflammatory infiltration. Later, interstitial fibrosis and tubular atrophy occurs. The atrophic tubules often contain eosinophilic proteinaceous casts, which look like thyroid follicles under light microscopy (thyroidization of the kidneys). Immune complex deposits are seen in various nephritic and nephrotic syndromes. Ischemic necrosis of the renal papillae is seen in diabetic nephropathy as well as analgesic nephropathy. Ischemic infarction of the kidneys can be seen in hemorrhage or conditions with extremely low cardiac output (i.e. shock).
