Brief Biography

Dr. Joana Dos Santos joined the Division of Urology at SickKids in July 2015 as the first Medical Urologist in Canada, and subsequently to the University of Toronto as an Assistant Professor of Paediatrics. 

After completing medical school at the Federal University of the State of Rio de Janeiro, she underwent Paediatrics and Paediatric Nephrology residency training at the Federal University of Sao Paulo, Brazil. Dos Santos started at SickKids in 2011 as research fellow in Paediatric Nephrology, later to become a true pioneer as the first Medical Urology Fellow with training focused on clinical management of urological conditions.

Research Interests

Dos Santos developed a new grading system for the management of Antenatal Hydronephrosis, which has been published in 2015. She is an active researcher interested in congenital abnormalities of the kidneys and urinary tract (CAKUT), renal stones, and bladder and bowel dysfunction in children. 

Dos Santos is responsible for the Medical Urology Clinic, as well as the Newborn Circumcision clinic, and is closely involved with the Combined Urology Nephrology Stone Clinic. She leads the Bladder and Bowel Dysfunction Network, an innovative initiative in which children with BBD who are referred to Urology at SickKids are re-referred to a network of community paediatricians in the GTA (closer to home) with close support of the Urology Division. Dos Santos is passionate about the medical management of urological conditions and continuous improvement of the care of children. She is currently enrolled in the Translational Research Master’s program at the University of Toronto.
