Urinary System -Q – Diagnostic Tests & Procedure & A – Meaning
| Question | Answer |
|---|---|
| cystoscopy | examination of the bladder using a rigid or flexible cystoscope |
| kidney biopsy (Bx) | removal of kidney tissue for pathologic examination |
| intravenous pyelogram (IVP) | 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) (Fig. 13-8) | 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 (e.g., a KUB before an IVP) |
| renal angiogram | x-ray image of the renal artery obtained after injecting contrast material into a catheter in the artery |
| retrograde pyelogram (RP) | 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, obstruction, etc. |
| voiding cystourethrogram (VCU or VCUG) | x-ray image of the bladder and urethra obtained during urination (voiding = urinating) |
| abdominal sonogram | abdominal ultrasound image of the urinary tract, including the kidney and bladder |
| urinalysis (UA) | physical, chemical, and microscopic examination of urine |
| specific gravity (SpGr) | measure of the concentration or dilution of urine |
| pH | measure of the acidity or alkalinity of urine |
| glucose | chemical test used to detect sugar in the urine; most often used to screen for diabetes (glucose = sugar) |
| albumin (alb) | 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 carbohydrates, 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 red blood cell hemolysis; indicates bleeding in the kidneys (occult = hidden) |
| bilirubin | chemical test used to detect bilirubin in the urine; seen in gallbladder and liver disease |
| urobilinogen | chemical test used to detect bile pigment in the urine; increased amounts are seen in gallbladder and liver disease |
| nitrite | chemical test to determine the presence of bacteria in the urine |
| microscopic findings (see Figs. 13-3 and 13-4) | microscopic identification of abnormal constituents in the urine (e.g., red blood cells, white blood cells, and casts); reported per high- or low-power field (hpf or lpf, respectively) |
| urine culture and sensitivity (C&S) | isolation of a urine specimen in a culture medium to propagate the growth of microorganisms; organisms that grow in the culture are identified, as are drugs to which they are sensitive |
| blood urea nitrogen (BUN) | blood test to determine the level of urea in the blood; a high BUN indicates the inability of one or both kidneys to excrete urea |
| creatinine, serum | test to determine the level of creatinine in the blood; useful in assessing kidney function |
| creatinine, urine | test to determine the level of creatinine in the urine |
| creatinine clearance testing | measurements of the level of creatinine in the blood and in a 24-hour urine specimen to determine the rate at which creatinine is “cleared” from the blood by the kidneys |
