Tests and procedures

If your child will be having the following tests done, it may be helpful for you and/or your child to know what to expect:

VCUG - (voiding cysto urethrogram)

This is a bladder test that is done by placing a small tube in the bladder through the urethra. The bladder is filled with an X-ray dye. Conditions diagnosed by a VCUG include:

Posterior urethral valves
Urethral stricture
Ureterocele
Vesicoureteral reflux
Bladder stones
Bladder tumors

Radionuclide cystogram

This test is similar to a VCUG, but is only used to diagnose vesicoureteral reflux. The test is done in a similar manner to the VCUG.

This is a non-invasive test that allows visualization of the bladder and kidneys. Sound waves are sent through the patient's body and the results give 2D images of the urinary tract. This test takes about 20 minutes.

DMSA Scan

This is a test that is used to determine kidney function. A special tracer is injected by intravenous and when injected will light up the kidney. The results of this test show areas of kidney infection or kidney damage. This test takes about one hour.

MAG 3 Renal Scan

This is a similar test to a DMSA scan, except it also allows us to determine if there is any blockage. The tracer is put into the urine and can be followed as it goes down into the bladder. In patients who have any blockage or obstruction in the urinary tract, the test shows that the tracer does not drain. This test can take up to an hour and a half.
