The ESPN Working Group CAKUT/UTI/Bladder Dysfunction was formed in 2013 and is dedicated to improve educational issues, clinical studies and research related to congenital malformations of the kidney and urinary tract, urinary tract infection and bladder dysfunction. Numerous experts, clinicians and researches throughout Europe have joined this Working Group which is open to new members at any time.

There is close collaboration of this WG with the ESPN, the CAKUT and Ciliopathies WG of the European Reference Network for Rare Kidney Diseases (ERKNet), other scientific societies (e.g. IPNA, ERA-EDTA and ASPN) and patient support organisations.

If you are interested in joining, please email Julia Hoefele including your institution, CV, special interests, and suggetions for the working group.
