555 University Avenue, 6th Floor, Atrium, Ward 6D

The Division of Pediatric Urology specializes in surgical and medical issues related to the kidneys, bladder, and genitalia. Our team does a full range of surgical services spanning the spectrum of acquired and congenital urogenital conditions, including renal transplantation and comprehensive paediatric urological cancer care.  

An interdisciplinary approach

Paediatric urological problems may require investigation beyond a clinical visit, as complexities of diagnosis may range from the most simple to the rarest and challenging. As a result, there is a strong relationship between Paediatric Urology and other medical disciplines (egnephrology, oncology, endocrinology, genetics), surgical colleagues (eg. gynaecology, paediatric surgery), and in particular with radiology (diagnostic imaging and image guided therapy). We will work together to provide the best care for your child! 

Sensitive care

We strive to provide state of the art management for all urogenital conditions, taking into account the behavioural and psychosocial aspects of each child and each problem. This approach acknowledges the often sensitive and personal aspects of each patient and his/her problem, allowing for an individualized approach using patient and family based care.  

Working together with you, our patients and families, we in Paediatric Urology at SickKids strive to give your child the normal, happy and healthy life they deserve. 

What we do

SickKids is a world leader in Paediatric Urology care. We manage medical and surgical care of the entire urological and genital systems for both boys and girls from infancy to adolescence. Paediatric Urologists specialize in surgical problems of the kidneys, the bladder and the genitalia. 

The Urology Clinic is the main site for delivery of all facets of clinical urology care to children and their families. The Paediatric Urology Clinic is staffed with doctors, experienced specialty urology nurses, nurse practitioners and clinical surgical associates with expertise in children's urology. Patients may be seen by a Nurse Practitioner, a staff physician or a Fellow. 

Integrated support from other key areas such as Diagnostic Imaging and Social Work form a vital part of the paediatric urology clinic experience. The Multidisciplinary Urogenital Clinics also take place in our clinic area on the fifth floor of the Atrium.

Fellows are clinicians who have completed their specialist training in either General Urology or General Paediatric Surgery, and are now adding to their training by spending dedicated time in Paediatric Urology. Although they are all experienced clinicians, in order to enhance their knowledge and expertise specific to Pediatric Urology they are supervised and supported by the staff Urologists of the Division in certain decision making and patient management. Your child/family is likely to encounter fellows at all stages of your care: in the Emergency Department, at your clinic appointment, at your OR appointment, and in the ward during your admission. 


Residents are licensed medical doctors training to be urologists. During their intensive training, residents work at different hospitals associated with the University of Toronto. 

Nurse Practitioners

Nurse practitioners (NPs) are registered nurses with additional education at the Masters level, advanced clinical experience and certified by exam through the College of Nurses of Ontario.  NPs can independently diagnose medical conditions, order and interpret diagnostic tests, and prescribe medication and other treatments.   

The NPs in our pediatric urology clinic work independently to provide safe and thorough medical care to all pediatric urology patients. They are especially valuable when managing those patients with chronic complex conditions to provide a consistent family-centered approach to achieving patient satisfaction. 

Flow Coordinator

A Flow Coordinator supports the medical team in providing care for patients, partnering with the patient and their family to coordinate all aspects of care and guides the flow through clinic from check-in to check-out. 

Our Flow Coordinator will check you in upon arrival to clinic.  Will take the patient's vital signs, perform non-invasive diagnostics (flowrates and bladder scans) if needed, assist with procedures, provide families with test information, offer surgical pre-op teaching, and book follow-up appointments. 

Child Life Specialist

A Child Life Specialist provides therapeutic play programs designed to reduce stress and help patients cope with hospitalization. They help prepare children for medical and surgical procedures and much more. 

Social Worker

A Social Worker can provide you with guidance on community resources with respect to accommodations, interpreter services, government agencies and forms and much more.

Research Registry: How you can help!

At SickKids Urology, we have a very good understanding of how to treat many problems in the urologic system of children. However, the reason that most of these problems occur to begin with is almost entirely unknown.  

We are constantly searching for even better ways to improve urology diagnosis and treatment. In order to do that, we must study and review the medical information of thousands of children just like your child in order to reach this goal, and answer the basic question ‘Why do urology conditions happen’? 

You can help our researchers make advancements in their field by participating in the Paediatric Urology Research Registry (PURR) - PDF.

Research Fellowship 

The Division of Urology offers a post-residency research fellowship to candidates who intend to pursue a career in academic urology. This program provides an opportunity for fellows to conduct clinical and/or basic science research in areas related to pediatric urology while working under the guidance of a research mentor. Please refer to our list of staff physicians for details on our team’s individual research interests. It is expected that the fellow will participate in the design, planning, and conduct of the research. While past research experience is not a requirement, it is desirable. Applicants are encouraged to secure funding to improve their opportunity of obtaining a research fellowship. Research fellowships can range from six months to two years. Must be fully funded. 

Clinical Fellowship

Our clinical fellowship is two years in length and is officially accredited by the Royal College of Physicians & Surgeons of Canada as an Area of Focused Competency (AFC) Program. Our unique and specialized training program provides Fellows with an opportunity to acquire an internationally recognized credential — the Diploma of the Royal College of Physicians and Surgeons of Canada (DRCPSC). This role is primarily clinical.

Research (80%), Clinical (20%) Fellowship

Research/clinical fellowships generally start for the first three to six months as solely research (see research fellowship description above), but with the opportunity to take on a clinical portion once the fellow has fully integrated into the division and has demonstrated some key clinical strengths needed.  Fellows will then have up to 20% of their time devoted to patient care activities to help maintain their clinical skills. Must be fully funded. 

Medical Urology Fellowship

The Division of Urology is pleased to announce the launch of the world's inaugural Medical Pediatric Urology Fellowship. This specialized program, tailored for pediatricians, offers comprehensive training in the clinical management of urological conditions. These conditions may be potentially surgical but require thorough clinical oversight in both inpatient and outpatient settings. The scope includes managing complex neurogenic bladder, congenital anomalies of the kidneys and urinary tract, bladder and bowel dysfunction, renal stones, hematuria, pre- and post-transplant urological care, uro-oncology, and office-based procedures such as neonatal circumcision and meatotomy. The 1-year program is primarily clinical, with an expectation that participants will undertake a research project and submit it for publication by the end of their training.
