Hepatorenal syndrome is a condition in which there is progressive kidney failure in a person with cirrhosis of the liver. It is a serious and often life-threatening complication of cirrhosis.
Hepatorenal syndrome occurs when there is a decrease in kidney function in a person with a liver disorder. Because less urine is removed from the body, nitrogen-containing waste products build up in the bloodstream (azotemia).
The disorder occurs in up to 10% of patients hospitalized with liver failure. It is caused by the mounting effects of liver damage and leads to kidney failure in people with:
Risk factors include:
- Blood pressure that falls when a person rises or suddenly changes position (orthostatic hypotension)
- Diuretic use
- Gastrointestinal bleeding
- Recent abdominal fluid tap (paracentesis)
Exams and Tests
This condition is diagnosed when other causes of kidney failure are ruled out by the appropriate tests.
A physical examination does not directly reveal kidney failure. However, the exam will usually show signs of chronic liver disease:
Other signs include:
- Abnormal reflexes
- Decreased testicle size
- Dull sound in the abdomen when tapped with the tips of the fingers, and visible fluid wave when examined by feel
- Increased breast tissue (gynecomastia)
- Sores (lesions) on the skin
The following may be signs of kidney failure:
The following may be signs of liver failure:
Treatment aims to improve liver function and ensure that there is enough blood volume in the body and that the heart is pumping it adequately.
The disorder is generally treated in the same way as kidney failure from any other cause.
- All unnecessary medicines should be stopped, especially the antibiotic neomycin, ibuprofen and other NSAIDs, and diuretics ("water pills").
- Dialysis may improve symptoms.
- Medications such as octreotide plus midodrine, albumin, or dopamine may be used temporarily to improve kidney function.
- A nonsurgical shunt (known as TIPS) is used to relieve the symptoms of ascites and may help kidney function. Surgery to place a shunt (called a Levine shunt) from the abdominal space (peritoneum) to the jugular vein may also relieve some of the symptoms of kidney failure. Both procedures are risky and proper selection of patients is very important.
The predicted outcome is poor. Death usually occurs as a result of secondary infections or hemorrhage.

This disorder most often is diagnosed in the hospital during treatment for a liver disorder.
