Procedure | Definition |
angiography | contrast dye is injected into the blood stream to view clots, tumors of the arteries, and veins of the kidneys |
blood urea nitrogen (BUN) | blood test to measure kidney function, measures the amount of urea in the blood |
clean catch specimen | after the urinary meatus is cleaned, a urine sample is collected after urination has begun |
catheterization | a sterile tube (catheter) is inserted into the bladder to obtain a urine specimen |
creatinine clearance | blood test to determine the kidneys filtering rate of removing creatinine from the blood |
cystography | xray of the bladder, conducted by inserting dye through a catheter |
cystometrogram | graphic recording of volumes and pressure in the bladder |
cystoscopy | visual exam of the bladder by inserting a cystoscope |
cystoscope with retrograde pyelogram | visual exam of the bladder, then xrays are taken of the kidney, ureter, and bladder after dye is inserted into the urethra |
cystourethroscopy | cystoscope is inserted through the urethra into the bladder to view the interior surface |
excretory urography | dye is injected into the bloodstream and xrays are taken of the kidney to track the excretion of the dye |
intravenous pyelogram (IVP) | dye is injected into the blood stream and xrays are done of the renal pelvis |
nephrotomography | sectional view xray of the kidney |
renal artery doppler | ultrasound study of the renal arteries |
renal biopsy | removal of a piece of kidney for microscopic examination |
renal scan | radioactive dye is injected in the blood stream and a scan is taken to determine blood vessel diameter, obstructions, and individual kidney function |
renal ultrasound | ultrasound waves produce images of the kidneys for visualization |
serum electrolyte level | measures the amount of sodium, potassium, and chloride in the blood |
technetiumcystogram | radioisotope is used to outline the bladder and an xray is taken |
transurethral biopsy | removal of a piece of kidney for microscopic examination that is taken through the urethra |
ureterography | dye study of the ureters |
urinalysis | analysis of urine for physical, chemical, and microscopic properties |
urine culture and sensitivity (C&S) | laboratory test to determine the bacteria in the urine and the antibiotic sensitivity |
urography | xray using contrast medium of the urinary tract |
voiding cystourethrography | xray taken while the patient is voiding |
xray of the kidneys, ureter, and bladder (KUB) | plain xray used to determine size and location of the kidney, ureter, and bladder |
