title: Hyperoxaluria and urinary tract calculi after jejunoileal bypass.
abstract: Five patients with jejunoileal shunt for morbid obesity in whom postshunt hyperoxaluria and recurrent urinary tract calculi developed are presented. All the stones were composed of calcium oxalate. The twenty-four hour urinary oxalic acid levels were also elevated in twenty of twenty-six patients who had had jejunoileal shunt for six months or longer. No correlation was present between urolithiasis and the degree of hyperoxaluria.
