any kidney disease that is degenerative & inflammatory
define RENAL FAILURE
damaged nephrons irreplaceable leads to failure & impressed filtration
aka: renal failure
kidney failure
describe AZOTEMIA
high blood urea nitrogen (BUN) bc lack of blood flow to kidney
describe UREMIA
toxic condition that can stem from azotemia from renal failure leading to waste being retained in the blood
aka: uremia
uremic poisoning

sudden onset associated w/uremia bc of not enough blood to kidney
cause: acute renal failure
dehydration, sudden drop in blood volume or BP, injury, burns, severe infection
describe CHRONIC KIDNEY DISEASE (CKD)
progressive loss of renal function leading to buildup of waste causing heart attacks & strokes

final stage of CKD that is fatal unless transplant or dialysis
aka: end stage renal disease
kidney failure
describe NEPHROTIC SYNDROME
group of s/s in disorders causing glomerulonephritis bc of excessive amnt of protein lost thru urine leading to low protein in blood

define PYONEPHROSIS
suppuration of kidney associated w/hydronephrosis
aka: pyonephrosis
nephropyosis
describe POLYCYSTIC KIDNEY DISEASE (PKD)
genetic condition where fluid-filled cysts in kidneys replace kidney mass & reduce function leading to kidney failure & enlargement
describe RENAL COLIC
acute pain in kidney from blockage bc of nephrolith that comes in waves
