The term "hepatorenal syndrome" is used to bring together a variety of syndromes whose common feature is liver and kidney parenchymal distress. For this reason, its use has been questioned by many workers. A subdivision into acute and chronic forms is proposed and emphasis is placed on the common physiopathogenetic processes, together with the notable importance of DIC. This approach is supported by reference to a series of 36 chronic and 6 acute cases.
