Signs 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:

  • Confusion (often due due to hepatic encephalopathy)
  • Excess fluid in the abdomen (ascites)
  • Jaundice
  • Other signs of liver failure

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:

  • Absent or low urine production, less than 400 cc/day
  • Fluid retention in the abdomen or extremities
  • Increased BUN and serum creatinine levels
  • Increased urine specific gravity and osmolality
  • Low serum sodium
  • Very low urine sodium concentration

The following may be signs of liver failure:

  • Abnormal prothrombin time (PT)
  • Increased serum ammonia levels
  • Low serum albumin
  • Paracentesis shows ascites
  • Signs of hepatic encephalopathy (an EEG may be performed if such signs are present)
