VCUG
Pronunciation: VEE-kug
Also written as: VCUG — voiding cystourethrogram
Imaging study that evaluates the bladder and urethra during urination to detect vesicoureteral reflux or anatomical abnormalities.
Full Definition
A voiding cystourethrogram (VCUG) is a fluoroscopic imaging procedure used to visualize the bladder and urethra during the voiding process. Contrast material is introduced into the bladder through a urethral catheter, and X-ray images are obtained as the patient urinates. This study is the gold standard for diagnosing and grading vesicoureteral reflux in children. VCUG can also identify structural abnormalities of the bladder and urethra, including posterior urethral valves in boys. The procedure requires catheterization, which can be distressing for pediatric patients.
Usage
Usage note: Also known as MCUG (micturating cystourethrogram) in some regions.
