Cytoscopy
Examination of the bladder using a rigid or flexible cystoscope
Intravenous pyelogram, intravenous urogram
X-ray image of the urinary tract obtained after an iodine contrast medium has been injected into the bloodstream; the contrast passes through the kidney and may reveal an obstruction, evidence of trauma,etc
Kidneys, ureters, bladder (KUB)
Abdominal x-ray image of the kidneys, ureters, and bladder; typically used as a scout film before obtaining an intravenous pyelogram (IVP)
Scout film
Plain-film x-ray image obtained to detect any obvious pathology before further imaging
Renal angiogram, renal arteriogram
X-ray image of the renal artery obtained after injecting contrast material into a catheter in the artery
Retrograde pyelogram, retrograde urogram
X-ray image of the bladder, ureters, and renal pelvis obtained after contrast medium has been injected up to the kidney by way of a small catheter passed through a cystoscope; used to detect the presence of stones, obstructions, etc
Voiding cystourethrogram
X-ray image of the bladder and urethra obtained during urination
Abdominal sonogram
Abdominal ultrasound image of the urinary tract, including the kidney and bladder
Urinalysis
Physical, Chemical, And microscopic examination of urine
Specific gravity (SpGr)
Measure of the concentration or dilution of urine
Albumin, protien
Chemical test used to detect the presence of albumin in the urine
Ketones
Chemical test used to detect the presence of ketone bodies in the urine; positive test indicates that fats are being used by the body instead of carbs, which occurs during starvation or an uncontrolled diabetic state
Urine occult blood
Chemical test for the presence of hidden blood in the urine resulting from RBC hemolysis; indicates bleeding in the kidneys
