Ch 20 Flashcards
analgesic nephropathy is associated w/
papillary necrosis
drug-induced hypersensitivity reaction of interstitiual and tubules leading to acute renal failure
tubulointerstitial nephritis
extensive accumulation of calcium phosphate crystals in tubules
acute phosphate nephropathy

Sporadic: 80%
Hereditary:
- deletions on chromosome 3
- loss of VHL
