Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken tackle the confusion around every aspect of our health and wellbeing.

Chris and Xand have always found the kidneys somewhat mysterious and elusive, going all the way back to medical school. Now they want to understand what makes this pair of organs so complex, and why they are so much more than simple filters. How do the kidneys work? What can happen when they go wrong? And how can we keep them healthy for as long as possible?

To answer these questions and more, the Docs are joined by Dr Kate Bramham, Consultant Nephrologist at King’s College Hospital and Reader at King's College London.
