Pre-appointment Instructions

Important pre-appointment instructions: 

Unless you have been instructed to fast, your child is permitted to eat and drink as normal. 

Your child may be required to provide a large volume of urine to send for testing. Please try to fill the container at least half full. If you do not have a container, one will be provided when you register at clinic. 

If your child is not toilet trained then the RN will assist you in obtaining a urine sample. 


The Kidney Stones Clinic is part of the Nephrology Clinic, located on the Main Floor, near the Black Wing Elevators. From the University Avenue entrance, walk in, turn right at the first hallway and stand in front of the Shoppers Drug Mart entrance. Walk straight past the Black Wing elevators and turn down the first hallway to your left. The Nephrology Clinic is the first clinic you will find on the left side of the hallway. 

From the Elizabeth Street Entrance and parking garage elevators, walk west (down Main Street) towards Shoppers Drug Mart. At the Family Centre/Library turn right. We are the first clinic you will find on the left side of this hallway. 

What to Expect During Your Visit

You will register at the clinic front desk upon arrival, and will be given requisitions for a urine sample and blood work (if needed). You may be directed to the Ultrasound Department if an ultrasound has been ordered. 

You will collect the urine sample in the bottle provided and drop it in the blue bin with the urine requisition. It should be at least half full to allow for testing. If your child is in diapers, one of the clinic nurses will apply a urine bag when your child is brought into the clinic. If blood work is needed you will be directed to the Ambulatory Care Centre. 

Once all the testing has been completed, please check back in at the front desk to let them know you are done. You will then be asked to wait in the waiting room located in the main hallway across from the Family Centre. A nurse will call your child’s name when it is your turn to come into clinic. The nurse will measure your child’s height, weight and blood pressure. You will then be seen by one of the doctors. SickKids is a teaching hospital where you may be seen by a medical student, resident or a fellow who will do an initial assessment and subsequently review with a staff nephrologist, who will then come to discuss the results and a plan of care. 

Please ensure you obtain new prescriptions for any kidney medications. 

Appointments may take a long time and we appreciate your patience.
