Controversies in acute kidney injury: the 2011 Brussels Roundtable

The recent advent of consensus definitions for acute kidney injury (AKI) has led to improvement in epidemiology of this complex disease and facilitated the development of new diagnostic makers and new therapies. However, important new challenges are also apparent. We still do not really understand why AKI occurs and urgently need to develop new therapies to treat it. Progress in this area will require new ideas and thinking outside the conventional box. By confronting some of the most significant controversies in the field of AKI we seek to develop new concepts that will ultimately yield new results.
