Clinic/registration location

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 5D.
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 5D.

When visiting SickKids an identification (ID) band will be placed on your child and must be worn on their arm or ankle at all times. To ensure your child is receiving the right care during their stay, the care team will use the ID band to check their name, date of birth and medical record number. If your child is sleeping, we’ll make sure to scan the ID band quickly and quietly so that we don’t disturb your child.  

The ID band is made of soft, latex-free material. There are two colours of ID bands: a black ID band indicates that your child has an allergy and a white ID band indicate there is no allergy. The allergy is not printed on the ID band, the care team will review the allergy in our electronic health record.

If your child’s ID band has fallen off or the information is incorrect, be sure to tell your care team. If they are not wearing an ID band or if they have the wrong one, it can lead to errors or delays that can result in the wrong care for your child.

Staff will always look at or scan the ID band before providing care to your child. This may involve

  • Asking parents or patients for two patient identifiers, such as the patient's full name and date of birth;
  • Scanning a barcode on the ID band to confirm the patient’s identity; or
  • Looking at the information on the ID band.

If you or your child are sick before your appointment

Call the clinic if you or your child have had a cold, cough, diarrhea, fever or rash within two days of your appointment, or have been sick with or exposed to chicken pox in the last three weeks. Your appointment may need to be rescheduled. 

Tell the clerk, nurse or doctor if your child has been in a hospital outside of Canada within the last 12 months. 

If you cannot come to your child’s appointment, it is important that you call the clinic as soon as possible to cancel and reschedule.

Be on time

If you are late, you may have to wait for other patients to be seen first. Allow lots of time to get to the hospital. It can take some time to get used to finding your way around and it is important to be on time for your child’s appointment. Staff will try to see your child as close to your appointment time as possible. Please understand that some patients being seen ahead of you may need more time than expected, and this can cause delay for others.

  • You must show valid health-care coverage at every visit. If you do not, you will be required to pay a fee for the visit, unless coverage or insurance can be verified.

Proof of health-care coverage must be valid at the time of visit (not expired).

    • If you live in Ontario, show your child’s valid Ontario Health Insurance Plan (OHIP) card.

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.

Try not to bring other children to the appointment

If other children must come, please consider taking them to the Play Park during your visit. The Play Park is a free, fun and safe place for brothers and sisters of patients to play. It is open Monday to Friday from 8:30 a.m. to 4 p.m. and weekends from 11:30 a.m. to 3:15 p.m. It is located on the Main Floor of the Atrium, next to the parking elevators. All children over 2 ½ years of age are welcome. Trained staff and volunteers will watch your children carefully. You do not need to book in advance to use the Play Park. The Play Park number is 416-813-8884.

Latex allergy

Call the clinic before coming to the hospital if your child or anyone coming with them has a known or suspected allergy to latex.


All visitor entrances on the Main Floor are wheelchair accessible. SickKids has several wheelchair-accessible washrooms on the Main Floor. Both male and female washrooms in the Atrium have large change tables where children and teens can have diapers changed. There is another private wheelchair-accessible washroom with a large change table on the Service Floor of the Black Wing in Room S213, across the hall from Rehabilitation Services. Wheelchairs are available near the Atrium and University Avenue entrances.

Assistance dogs for children or parents with disabilities are allowed at SickKids. Please make sure they are clean and have up-to-date immunizations.

Interpreter Services

If you need an interpreter, please call the clinic before your appointment so we can arrange for an interpreter. There is no charge for an interpreter. Please give us at least 24 to 48 hours' notice to make it easier for us to find an interpreter for you.

What to expect during your visit

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 10-60 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.
