ERKNet Reference Center


Toulouse, Toulouse, University Hospital


Pediatric Nephrology Unit of the University Hospital


The Unit of Pediatric Nephrology of the University Hospital of Toulouse is the reference center for rare renal disease (SORARE) of the South West of France. SORARE has a special clinical focus on (1) inherited renal disease (especially, cystic kidney diseases (ADPKD, ARPKD, HNF1B-related disease) and CAKUT) and (2) immune glomerulonephritis and thrombotic microangiopathy. Also, all the acute and chronic renal replacement therapies are available in our pediatric center (intermittent and continuous dialysis, plasma exchanges, immunoadsorption) and a medical intensive care unit is included in our Department. Our group is composed of nephrologists, immunologists, intensivists, and psychologists and regular staff with medical geneticists are organized. In addition, we developed a program of clinical and experimental research in the field of HNF1B-related nephropathy, CAKUT, especially hyperechogenic kidneys and posterior urethral valves, and renal fibrosis, in collaboration with the J. Schanstra's laboratory from the Institut National de la Santé et de la Recherche Médicale (Institut des Maladies Métaboliques et Cardiovasculaires, U1048, Toulouse). Last, we conducted and participated to several investigator and industry-driven clinical trials.
