Parenchymal Disorders Flashcards
what is atheroembolic disease of the kidneys?
when athero plaques break off and block vessels in the small arterioles and caps of the kidney
does contrast lead to constriction or dilation of medullary vessels? what can this cause?
constriction…can lead to tubular damage and AKI
what is a scenario where you should not give contrast dye?
never give when GFR is less than 60
will atheroembolic disease present with acute renal failure or chronic?
usually presents with acute
what is the rash called that is seen in atheroembolic disease?
livedo reticularis
how does atheroembolic disease affect complement 3 and 4?
3 down and 4 normal
what type of cell is seen in urine with atheroembolic disease?
eosinophils
fluorquinolones commonly cause what type of renal injury?
acute interstitial nephritis
myoglobin break down can lead to what kind of kidney disease?
nephrotoxic acute tubular necrosis
when myoglobin is breaking down…what happens to the phosphate and calcium levels?
phosphate goes up and calcium goes down
name two situations where FENa is always unreliable?
chronic kidney disease
diuretic use
renal vein thrombosis presents with what two symptoms?
hematuria
flank pain
tumor lysis syndrome leads to what two things in kidneys?
uric acid crystals and calcium phosphate stones
calcium phosphate crystals and uric acid crystals are high in what syndrome?
tumor lysis syndrome
describe how tumor lysis syndrome causes renal failure
nucleic acids are released from cells and converted into uric acid which then uric acid crystals accumulate and block tubules
