A Voiding Cystourethrogram studies the functioning of the urinary tract including the bladder. Patients need this exam for voiding dysfunctions, urinary tract infections (UTI), bed-wetting and other diagnoses of the urinary tract.

During a VCUG, a catheter is inserted into the bladder and dye is injected through the catheter to fill the bladder.

You will then be asked to urinate as the radiologist watches on an X-ray monitor.

This procedure may be uncomfortable, but it is not painful. For children having a VCUG, parents may be asked to assist in keeping the patient calm. Patients are not sedated for this procedure, which takes about 30 to 45 minutes.

Afterward, you should drink plenty of fluids to flush the contrast material out of your system. If you experience discomfort, try taking a warm bath.
