the body in a wide variety of clinical settings

can lead to DIC
Term
Definition of Chronic Pyelonephritis
Definition
Chronic inflammation
Term
Etiology of Chronic Pyelonephritis
Definition
obstruction or chronic reflux-associated disease
Term
Pathogenesis of Chronic Pyelonephritis
Definition
greater stasis and infection leads to widespread destruction of the kidney
Term
Clinical course of Chronic Pyelonephritis
Definition
can progress to chronic renal failure
Term
Mechanisms by which drugs and toxins can produce renal injury
Definition
cause interstitial immunologic reaction which can cause acute renal failure by direct tubular damage or subtle injury leading to chronic renal insufficiency
Term
Definition of Acute tubular necrosis
Definition
all forms of acute renal failure associated with destruction of tubular epithelial cells
Term
Causes of acute tubular necrosis
Definition
hypotensive episode (shock) or ingestion, injection or inhalation of toxic agent
Term
Clinical significance of acute tubular necrosis
Definition
there is a massive water loss which is reversible
Term
Definition of benign hypertension
Definition
disease of the blood vessel in which there is a thickening of small arterial walls and arteriole walls in the kidney
Term
Clinical significance of benign hypertension
Definition
renal ischemia rarely causes renal insufficiency

Term
Morphology of renal infarcts
Definition
white, wedge-shaped with base against cortical surface and apex pointing toward medulla
Term
Clinical Signficance of renal infarcts
Definition
much of blood supply is filtered through kidney
Term
