Tubulointerstitial Disorders Flashcards
Disorders that affect interstitial space surrounding the renal tubules
tubulointerstitial disease
True or false: tubulointersitial disease can be acute or chronic?
True
Chronic conditions of tubulointerstitial disease include
fibrosis and atrophy
Acute conditions of tubulointerstitial disease include
rapid onset characterized mainly by edema
Infection of kidney tissue and pelvis
pyelonephritis
True or false: pyelonephritis is only acute
False
It can be acute or chronic
Main cause of acute pyelonephritis?
hematogenous spread of bacteria or infection via the urethra or instrumentation (catheters)
What type of bacteria in pyelonephritis?
gram-negative
E.coli or Enterococcus faecalis
pus in urine
pyuria
Causes of chronic pyelonephritis?
ideopathic or associated with renal obstruction or reflux
abscess formation
recurrent or persistent infection from urinary obstruction or urinary reflux
s/sx acute pyelonephritis
flank pain
fever/chills
frequency
dysuria
Most common cause of rapid acute kidney failure
acute tubular necrosis
What are the 2 categories of ATN
ischemic
nephrotoxic
What type of ATN results from decreased perfusion or inadequate oxygenation to renal tubules
ischemic
What type of ATN results from a number of agents that directly and specifically damage the renal tubules
nephrotoxic
