What is a voiding Cystourethrography used for?

A voiding cystourethrogram, or VCUG, is a study used to look at bladder and urethral abnormalities and to determine if you have ureteral reflux. Ureteral reflux means urine in the bladder is flowing back into the ureters (the tubes leading from the kidneys to the bladder). This can result in kidney infections.
