A middle aged man with no antecedent renal disease developed progressive renal insufficiency first detected 2 yr after jejunoileal bypass surgery for obesity. Hyperoxaluria (mean ± SE oxalate excretion = 69 ± 9 mg/24 hr) and an interstitial nephritis with calcium oxalate deposition within the renal parenchyma were observed. After surgical restoration of bowel continuity, oxalase excretion fell to normal (36 ± 6 mg/24 hr) and renal function stabilized.
