Chapter 7 Procedures Flashcards
BUN (blood urea nitrogen)
measurement of urea levels in blood
creatinine clearance
measurement of the rate at which creatinine is cleared from the blood by the kidney
CT urography
x-ray images obtained using computed tomography (CT) show multiple cross-sectional and other views of the kidney
KUB (kidneys, ureters, and bladder)
x-ray examination (without contrast) of the kidneys, ureters, and bladder
renal angiography
x-ray examination (with contrast) of the blood vessels of the kidney
retrograde pyelogram (RP)
x-ray image of the renal pelvis and ureters after injection of contrast through a urinary catheter into the ureters from the bladder
voiding cystourethrogram (VCUG)
x-ray image (with contrast) of the urinary bladder and urethra obtained while the patient is voiding
ultrasonography
imaging of urinary tract structures using high-frequency sound waves
radioisotope scan
image of the kidney obtained after injecting a radioactive substance (radioisotope) into the bloodstream
MRI urography
changing magnetic field produces images of the kidney and surrounding structures in three planes of the body
cytoscopy
direct visualization of the urethra and urinary bladder with an endoscope (cystoscope)
dialysis
process of separating nitrogenous waste materials from the blood
lithotripsy
urinary tract stones are crushed
renal angioplasty
dilation of narrowed areas in renal arteries
renal biopsy
removal of kidney tissue for microscopic examination
