A fascinating scientific paper has highlighted the exciting innovations in kidney replacement therapy happening worldwide, with several breakthroughs that could transform life for kidney patients in the coming years.

While the original paper is written for an academic audience, the National Kidney Federation wants to share these exciting technological developments that offer hope for more mobile, accessible and effective treatments.

Technological innovations should continue to transform kidney care. Researchers are developing smaller, more portable dialysis systems that require less infrastructure, potentially bringing life-saving treatment to millions more people worldwide.

Several exciting technologies are in development or human trials:

Wearable Peritoneal Dialysis Systems:

• The VIVANCE system (formerly AWAK) from Singapore uses innovative technology to regenerate dialysis fluid, making it portable enough to carry in a shoulder bag
• Malaysia's Peritocare system offers a wearable Peritoneal Dialysis solution that completed human trials in 2022
• The Dutch Weakid system provides both day and night treatment options with a mobile console and cartridge system

Portable Haemodialysis:

• NextKidney's Neokidney device is small enough to meet airline carry-on requirements – a huge leap forward in mobility
• Other systems are dramatically reducing water and electricity needs by regenerating dialysis fluid rather than discarding it

Implantable Artificial Kidneys

Perhaps most exciting are the advances toward fully implantable artificial kidneys. Teams in both the US and Europe are making progress on devices that would:

• Eliminate the need for external blood circulation
• Use silicon-based nanoporous filters smaller than a smartphone
• Include bioreactors with living kidney cells to perform some kidney functions
• Connect directly to the bladder to eliminate waste

The Gut as a "Third Kidney"

Researchers are even exploring how the gut might help remove some kidney toxins, potentially simplifying dialysis requirements and offering support during earlier stages of kidney disease.

Challenges Remain

Despite these promising developments, funding remains a significant obstacle. Kidney innovation receives relatively modest funding despite affecting millions of lives.

The National Kidney Federation will continue to monitor these developments and advocate for increased investment in kidney innovation. We encourage patients to join us in making their voices heard to accelerate progress on these life-changing technologies. We have summarised findings we thought of interest to our members from the academic paper found here for those interested in reading this in full.
