VCUG  (Voiding Cystourethrogram)

Voiding cystourethrogram 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 while pictures are taken with a fluoroscopy. A radiologist determines if the solution is going back up into the kidneys. This test is commonly done in evaluating a variety of conditions involving the urinary tract.
