Cystogram / Voiding Cystourethrogram

A cystogram is an examination of the bladder using x-ray dye or contrast. A voiding cystourethrogram (VCUG) is an examination of the bladder and the lower urinary tract or urethra (tube which carries urine out of the bladder) using x-ray contrast. A cystogram is recommended when trauma occurs to the bladder or a growth in the bladder is suspected. A VCUG is recommended after a frequent urinary tract infections to check for a condition known as vesicoureteral reflux. This condition is caused by a reverse flow of urine from the bladder into the drainage system of the kidneys.

Both the cystogram and VCUG take 30 minutes to perform. You will be given a gown to change into. A technologist will assist you onto the x-ray table. A small tube will be inserted through the urethra into the bladder. You will feel a pressure sensation while the tube is being inserted. The tube is then connected to contrast material that drips by gravity into the bladder. For a cystogram, films will be taken when the bladder is full. For a VCUG, films are taken when your bladder is full, while you are emptying your bladder and once your bladder is empty.

After the exam, a radiologist will prepare a report for your physician and forward it to his or her office.

Patient Preparation:

  1. There are no other special preparations.

After Discharge:

  1. There is a slight chance that you may have a little blood in the urine during the first two times you go to the bathroom. This is normal and will clear.
  2. You may feel a burning sensation the first few times you go to the bathroom. This is normal and will subside.
  3. Contact your doctor if you develop fever, increase urination, and worsening pain with urination.

Precautions:

    1. This procedure should not be performed during active urinary tract infections.
    2. Patients who are allergic to iodine and/or shellfish should inform the technologist prior to the study.
    3. Because x-ray is used for this study you should inform the doctor or technologist if there is any possibility that you are pregnant.
