The registration to the interventional nephology course is not included in WCN registration fees. It can be purchased separately for 165 USD. Places are limited and will be sold on a first-come, first-served basis.

The rest of the courses are included with WCN registration. To attend, for organizational purposes, we kindly ask delegates to indicate whether they plan to attend the courses taking place on March 28. This is for planning only – it is not a commitment, and delegates are free to change their minds later.

Please note that onsite access to the courses will be based on room capacity and available seating, on a first-come, first-served basis
