Voiding Cystourethrogram (VCUG)

VCUG stands for voiding cystourethrogram. A VCUG is an imaging procedure used to evaluate the functioning of your bladder. We will place a small catheter into the bladder through the urethra. The radiologist will fill your bladder with contrast material and take a series of X-Rays. When your bladder is full, you will be asked to urinate to look for reflux of urine into the ureters. 

Your physician will give you detailed instructions on how to prepare for your VCUG. Please inform your physician of any medications you are taking as well as any allergies you may have. Also inform your physician regarding a recent illness or other medical conditions.

Women should inform their physician if they are pregnant, or if there is any possibility they may be pregnant.

Radiation Dose: Special care is taken during X-Ray examinations to use of the lowest radiation dose possible while producing the best images for evaluation.
