Voiding cystourethrogram
One method of examining bladder function is by injecting dye
that is visible on x-rays through a tube (catheter) to fill the
bladder. X-rays are taken while the bladder is full and while the
patient is urinating (voiding) to determine if fluid is forced out
of the bladder through the urethra (normal) or up through the
ureters into the kidney (vesicoureteral reflux). This study is
usually done while the patient is lying on an x-ray table.
