Hepatorenal syndrome

The exact physiologic mechanism of the hepatorenal syndrome remains unclear; however, it always develops in the presence of liver failure. A number of theories have been postulated to explain the syndrome, which are discussed in this review. None of the proposed theories is able to explain the syndrome completely, and continued research is necessary. Management of hepatorenal syndrome is directed at supporting the patient and maintaining/restoring hepatic function to prevent further renal damage. Liver transplantation has been considered an effective method of treatment for this patient population. Nursing care is supportive and focuses on maintaining the patients' internal environment and psychologic well-being.
