Unit 3 Flashcards

process for removing waste products
urea
nitrogenous waste formed in the liver
other names for urination
voiding or micturition
kidney secretes:
renin and erythropoietin (EPO)
renin
raises blood pressure to keep blood moving through kidney
EPO
stimulates production of RBC

substance that forms
cortic/o

regions of kidney
cortex and medulla
nephron
processing blood plasma and urine formation
glomerul/o
glomerulus
glomerulus
blood enters nephron through this ball of capillaries, act as filters
renal tubules
substances filtered here
collecting duct
many nephron tubules form this
reabsorption

things to test in urine
color, pH, albumin, glucose

excess levels of hemoglobin pigment bilirubin in the blood
specific gravity
comparison of density between the urine and water, reflects the amount of wastes, minerals, and solids in the urine
Upper UTIs
kidneys and ureters
lower UTIs
bladder and urethra
possible causes of renal failure
high blood pressure, infection, and diabetes
chronic kidney disease (CKD)
end-stage renal disease, can be fatal
interstitial nephritis
inflammation of tissue between renal tubules
An acute reaction to certain drugs that leads to poor renal function, fever, and rash accompanied by eosinophils in the urine
interstitial cystitis (IC)
chronic inflammation of the bladder wall
pyelonephritis
bacterial infection in the renal pelvis of the urinary tract causes collections of pus to form in the kidney

scarring causing a fibrotic narrowing of the urethra
dysuria
painful urination
polyuria
urinating frequently
diuresis
increased urine formation and secretion
nocturia
frequent, excessive urination at night
anuria
diminished or absent urination

condition of having a kidney stone
hypercalciuria
elevated calcium, thought to form kidney stones
polycystic kidney disease (PKD)
multiple cysts form inside and outside kidney
uremia
a large amount of nitrogenous wastes accumulate in the blood because they are not being excreted in the urine
Azotemia
high levels of urea
diabetes insipidus (DI)
ADH is not secreted or kidney becomes resistant to it
diabetes mellitus
insulin is either not adequately secreted or tissues are resistant to its effects
polydipsia
excess thirst

kidney disease with proteinuria, hypoalbuminemia, and edema
Glomerulonephritis
inflammation of glomeruli
normal pH of urine
slightly acidic
blood urea nitrogen (BUN) test
determine how much urea and nitrogen have accumulated in the blood
creatinine clearance test (CrCl)
measures the rate at which creatinine concentration in a blood sample is excreted in the urine over a 24-hour period and can assess glomerular filtration rate (GFR)
retrograde pyelogram (RP)
administration of a contrast medium through a catheter into the ureters from the bladder before x-ray images of the renal pelvis and ureters are taken
radioisotope scan
image of the kidney enhanced by the injection of a radioactive substance into the bloodstream
voiding cystourethrogram (VCUG)
the bladder is filled with a contrast material, and real-time x-ray imaging (fluoroscopy) is performed as the patient expels urine
intravenous pyelogram (IVP)
x-ray examination of the kidneys, bladder, and ureters with iodine contrast
urography / KUB
kidney, ureters, and bladder examination, x-ray examination, without contrast medium to see size and location of kidneys
