What is the ISN Doing About the Challenge of Chronic Kidney Disease of Unknown Origin?

Despite ongoing efforts, chronic kidney disease of unknown origin (CKDu) remains a significant, persistent challenge in several world regions.

As part of its commitment to advancing equitable kidney care worldwide, the ISN launched the ISN i3C (CKDu) Network at WCN 2017 to facilitate global CKDu-related collaboration and data collection and dissemination. Explore the details of current endeavors below and get involved!


Read the ISN i3C Working Group’s paper, “Kidney Biopsies Among Persons Living in Hotspots of CKDu: A Position Statement From the International Society of Nephrology’s Consortium of Collaborators on CKDu,” recently published in Kidney International®.
