Urodynamics Testing Clinic

Urodynamics refers to a series of diagnostic tests that evaluate the function of your child’s bladder and urethra. Urodynamics tests provide valuable information to aid in the accurate diagnosis of your child’s urinary problems.

What to bring: 

• Urine and/or blood reports 

Important pre-appointment instructions: 

Your child may have been asked to complete a bladder diary or questionnaire. If so, please bring this with you to the appointment. 

Directions: 

If this is your child’s first visit to SickKids you need to register for your appointment at Clinic Registration near the Atrium entrance on Elizabeth Street. Arrive early so you have enough time to register. 

If this is a return visit to SickKids you need to register in the Urology Clinic on Unit 6D. The Urology Clinic is located on the fifth floor of the Atrium. Take the Atrium elevator to the fifth floor and look for the D sign. That will lead you to 6D. 

Unless otherwise directed by your child’s doctor, your child should take their normally scheduled medications. Your child may eat and drink prior to the tests. These tests typically take 10 to 60 minutes. Your child will be able to resume all previous activities upon completion of the urodynamics tests. 

Your child will need a full bladder for the flow rate test. It takes 20 to 30 minutes for liquid to get down to the bladder. If your child does not normally drink a lot of water or if your child has been ill, your child may be slightly dehydrated. If your child is dehydrated, it will take more water to fill the bladder. You can bring their favourite drinks from home or buy a drink in the hospital. Every child has a different bladder capacity. We want to do this test when your child feels a strong urge to urinate. A strong urge to urinate shows that your child's bladder is full. If your child is not ready for the test when you arrive at the clinic, encourage your child to drink water. When your child feels a strong urge to urinate, please tell the clerical staff at the front desk. 

Once your child's bladder is full, the test will take about 5-10 minutes. Your child will have a bladder scan and will be asked to urinate into the flow rate toilet. Then your child will have a second bladder scan to see if any urine is left in the bladder.   

The full urodynamic study is also performed in our clinic and requires an empty bladder. The registered nurse will contact you before coming for this appointment and explain this test in details. 

The video urodynamic study is performed in the Department of Diagnostic Imaging on the 2nd floor. If you are unsure about the location of the department, ask at the Main Reception near the Elizabeth Street entrance. This study also requires an empty bladder. The registered nurse will contact you before coming for this appointment and explain this test in detail. 

At the end of this study, a doctor or nurse practitioner in the Urology Clinic will review the test results. If your family physician or paediatrician has sent your child for this test, the results will be forwarded to them. 

If any referrals or follow-up appointments are needed, the clinic coordinator/clerk will be available to assist you with scheduling an appointment. At the end of the appointment, you will be given an appointment card or your appointment will be mailed to you, depending on booking availabilities.
