Oxalate-induced acute renal failure in Crohn's disease.

In a patient with long-standing Crohn's disease and bowel resection, acute reversible renal failure associated with hyperoxaluria developed. The renal biopsy specimen demonstrated marked oxalosis. Acute renal failure, although rare, is a complication of enteric hyperoxaluria of Crohn's disease. This type of renal failure may be reversible if recognized and treated early, since remission of symptoms occurred following hemodialysis.
