How does the voiding cystourethrogram ( VCUG ) test work?

Voiding cystourethrogram (VCUG). This test uses X-rays of the bladder when it’s full and when it’s emptying to detect abnormalities. A thin, flexible tube (catheter) is inserted through the urethra and into the bladder while your child lies on his or her back on an X-ray table.

Once in this area, the water enters a relief valve sensing line.

Can a VCUG detect vesicoureteral reflux ( Vu )?

Sometimes VU reflux only occurs while urinating (voiding), which is why the VCUG includes taking X-ray images while the bladder is being emptied.
