Qualified paediatricians (FMH) can additionally specialise in paediatric nephrology, which refers to the diagnosis and treatment of kidney and urinary tract diseases in children. Doctors with this specialisation treat children of all ages with kidney or urinary tract diseases, from newborn babies to young adults.

Paediatric nephrologists have specialist knowledge and skills in the treatment and supervision of children and adolescents with acute or chronic kidney insufficiency. This includes dialysis treatments (blood cleansing) at home or at the hospital, as well as the provision of medical care before and after kidney transplants.  Paediatric nephrologists collaborate closely with other professionals such as nutritionists, nurses, physiotherapists, nephrologists and transplant specialists.
