All of the following are seen in patients with acute renal failure, EXCEPT:

Although hyperuricemia (serum uric acid level of 12-15 mg/dl) is seen in patients with acute renal failure, acute uric acid nephropathy is an unusual phenomenon. Volume overload in patients with acute renal failure is responsible for weight gain, edema, pulmonary rales and hypeension. Retention of potassium and hydrogen ions in acute renal failure causes hyperkalemia metabolic acidosis. Hyperphosphatemia in acute renal failure is associated with metastatic calcification and subsequent reduction of serum calcium level. Other complications of acute renal failure include infection, hemorrhagic diathesis and anemia. Ref: Wyatt C., Kemp W.L., Moos P.J., Burns D.K., Brown T.G. (2008). Chapter 16.
