A VCUG, or Voiding Cystourethrogram, is a diagnostic procedure used to examine the bladder and urethra while the bladder fills and empties. This test is particularly useful for identifying issues such as vesicoureteral reflux (where urine flows backward from the bladder towards the kidneys), blockages, or other abnormalities of the urinary tract. Understanding the process and what to expect can help alleviate any concerns you may have as a parent. Here's a patient information sheet to guide you through the VCUG procedure for your child:

What is a VCUG?

A VCUG is a type of X-ray test that provides detailed images of the lower urinary tract, including the bladder and urethra. It involves the insertion of a catheter into the bladder through the urethra, followed by the filling of the bladder with a contrast fluid that is visible on X-rays. The test allows doctors to see how the bladder fills and empties and to check for any abnormalities.

Why is a VCUG Needed?

Your child's doctor may recommend a VCUG to:

• Investigate recurrent urinary tract infections.

• Check for vesicoureteral reflux (backward flow of urine from the bladder to the kidneys).

• Identify abnormalities in the structure of the urinary tract.

• Evaluate issues related to incomplete emptying of the bladder.

Before the Test

• Preparation: There is minimal preparation required for a VCUG. You may be asked to make sure your child has an empty bladder before the procedure. It's important to explain the procedure to your child in a way that is appropriate for their age to help reduce any anxiety.

• What to Bring: Comfort items such as a favorite toy or blanket can be helpful for your child's comfort and security.

During the Test

• The procedure is performed in the radiology department of a hospital or a specialized outpatient center.

• Your child will be positioned on an X-ray table, and a catheter will be gently inserted into the bladder through the urethra.

• Once the catheter is in place, the bladder is filled with a special dye that shows up on X-rays.

• X-ray images will be taken as the bladder fills and then as your child urinates to empty the bladder. The radiologist will monitor the flow of urine and check for any abnormalities.

• The procedure usually takes about 30 minutes to an hour.

• Your presence: Depending on the facility's policy and your child's age and comfort level, you may be allowed to stay with your child during the test to provide reassurance.

After the Test

• Immediate Care: After the VCUG, the catheter is removed. Your child may feel a slight discomfort or have a burning sensation during their first few urinations after the test.

• Observation: Watch for signs of infection, such as fever, pain, or difficulty urinating. While rare, infections can occur and may require prompt treatment.

• Results: The results of the VCUG will be analyzed by a radiologist and the x-ray films will most likely be shared with you on the same day. Reports of the investigation can be collected on the next visit to your doctor in 3-4 days.
