What is a micturationg cystogram?

This test uses X-rays to study how the bladder fills and empties. The doctor in the clinic will have explained why your child needs this examination. However if you don’t understand, please ask.

What does it involve?

This test is normally done in the X-ray department.

A fine, plastic tube (catheter) is passed into your child’s bladder through the urethra (the tube through which urine is passed).

The doctor will fill the bladder using X-ray dye until it starts emptying naturally.

X-ray pictures are then taken.

Normally one parent/carer will be able to stay with the child during the examination.

How long does it take?

The test usually takes about 15 minutes.

What preparations are needed?

Before the X-ray, please report to the children’s ward (Caroline Thorpe Ward) on Level 3 at the North Devon District Hospital.

You can discuss with the doctors whether it would help your child to have some medicine (sedation) to make them sleepy and relaxed before the test.

If you think your child has a urine infection when the test is due, we will not be able to do it. Please telephone us for advice.

If your child is allergic to iodine or dyes used in the X-ray department, please telephone us for advice on 01271 322741, Monday to Friday between 9am and 5pm.

Are there any risks/after effects?

Because we pass a tube into the bladder there is a small risk of introducing infection. Most children needing this test are already on low dose long-term antibiotics, which reduces this risk.

Your specialist will make arrangements to increase the dose of these antibiotics at the time of the test. If you have not heard from your specialist one week before the test, or if your child is not on antibiotics, please contact the children’s ward for advice.

The dye is used for many X-ray tests and rarely people are allergic to it. If this happens, treatment is available in the X-ray department and if necessary on the ward afterwards.

What happens after the test?

Your child will go back to the ward before going home. The ward doctors will decide whether they need to increase the dose of antibiotics your child is taking.

In the week after the test if your child shows any symptoms of a urinary infection, such as pain passing urine, a temperature or seems unwell, please contact your GP for advice.
