The development of decompensation in patients with cirrhosis is associated with increased mortality. Renal function gradually deteriorates with significant hemodynamic changes associated with decompensated liver disease, but may also rapidly decrease in response to precipitating events. Newer definitions of renal dysfunction may result in early diagnosis, this along with the use of sensitive markers helps in accurate determination of renal function in cirrhosis. Although renal dysfunction progresses slowly in cirrhotic patients, it is associated with increased mortality. Prompt intervention with appropriate management reduces the risk of renal dysfunction, as well as improving survival and quality of life. Appropriate management may include the removal of precipitating causes and use of pharmacological agents supporting circulatory dysfunction. Outcomes following treatment of this condition remain a major concern, especially in patients who develop hepatorenal syndrome. Transplantation of the liver or kidney and liver may be the only option when other modalities of treatment fail. Early transplantation may benefit these patients.
