<unk>  <unk>  is an umbrella term used in the medical field that defines disorders of the heart and kidneys whereby “acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other”. The heart and the kidneys are involved in maintaining hemodynamic stability and organ perfusion through an intricate network. These two organs communicate with one another through a variety of pathways in an interdependent relationship. In a 2004 report from National Heart, Lung and Blood Institute,<unk>  was defined as a condition where treatment of congestive heart failure is limited by decline in kidney function. This definition has since been challenged repeatedly but there still remains little consensus over a universally accepted definition for<unk> . At a consensus conference of the Acute Dialysis Quality Initiative (ADQI), the<unk>  was classified into five subtypes primarily based upon the organ that initiated the insult as well as the acuity of disease.
Cardiorenal syndrome
Conorenal syndrome
Papillorenal syndrome
Hepatorenal syndrome
Nephritic syndrome
Tumor lysis syndrome
Monofixation syndrome
Dialysis disequilibrium syndrome
