Voiding Cystourethrogram (VCUG)

A VCUG 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 (urine channel) and into the bladder while your child lies on his or her back on an X-ray table. After contrast dye is injected into the bladder through the catheter, your child's bladder is X-rayed in various positions. Then the catheter is removed so that your child can urinate, and more X-rays are taken of the bladder and urethra during urination to see whether the urinary tract is functioning correctly.
