Urinary Tests and Clinical Procedures

Question 1

Measurement of urea levels in the blood.

Answer 1

BUN (blood urea nitrogen)

Question 2

Measurement of the rate at which creatinine is cleared from the blood by the kidney.

Answer 2

creatinine clearance

Question 3

X-ray images obtained using computed tomography show multiple cross-sectional and other views of the kidney.

Answer 3

CT urography

Question 4

X-ray examination (without contrast) of the kidneys, ureters, and bladder.

Answer 4

KUB (kidneys, ureters, and bladder)

Question 5

X-ray examination (with contrast) of the blood vessels of the kidney.

Answer 5

renal angiography

Question 6

X-ray image of the renal pelvis and ureters after injection of contrast through a urinary catheter into the ureters from the bladder.

Answer 6

retrograde pyelogram (RP)

Question 7

X-ray image (with contrast) of the urinary bladder and urethra obtained white the patient is voiding.

Answer 7

voiding cystourethrogram (VCUG)

Question 8

Imaging of urinary tract structures using high-frequency sound waves.

Answer 8

ultrasonography

Question 9

Image of the kidney obtained after injection a radioactive substance (radioisotope) into the bloodstream.

Answer 9

radioisotope scan

Question 10

Changing magnetic field produces images if the kidney and surrounding structures in three planes is the body.

Answer 10

MRI urography

Question 11

Direct visualization of the urethra and urinary bladder with an endoscope (cystoscope). Either flexible or rigid.

Answer 11

cystoscopy

Question 12

Process of separating nitrogenous waste materials from the blood. There are two methods.

Answer 12

dialysis

Question 13

Uses an artificial kidney machine that receives waste-filled blood from the patient’s bloodstream, filters it through an artificial porous membrane (dialyzer), and returns the dialyzed blood to the body.

Answer 13

hemodialysis (HD)

Question 14

Uses a catheter to introduce fluid into the peritoneal (abdominal) cavity. Waste materials, such as urea, in the capillaries of the peritoneum pass out of the bloodstream and into the fluid. The fluid (with wastes) is then removed by the catheter.

Answer 14

peritoneal dialysis (PD)

Question 15

Urinary tract stones are crushed. The extracorporeal method uses shock waves directed toward the stone from outside the body. Stones pass from the body in urine after the procedure.

Answer 15

lithotripsy

Question 16

Dilation of narrowed areas in renal arteries.

Answer 16

renal angioplasty

Question 17

Removal of kidney tissue for microscopic examination.

Answer 17

renal biopsy

Question 18

Surgical transfer of a kidney from a donor to a recipient.

Answer 18

renal transplantation

Question 19

Passage of a flexible, tubular instrument through the urethra into the urinary bladder.

Answer 19

urinary catheterization

Question 20

Indwelling catheter held in place by a balloon inflated with liquid.

Answer 20

Foley catheter
