A Jejuno-ileal Bypass Patient Presenting with Recurrent Renal Stones due to Primary Hyperparathyroidism.
In the past, jejuno-ileal (JI) bypass operations were performed for the treatment of massive intractable obesity. This procedure is known to be complicated by numerous malabsorptive syndromes, occasionally resulting in electrolyte abnormalities and oxalate renal calculi. Recurring renal stones and oxalate nephropathy are cause to reverse the JI bypass. However, investigation of recurring renal stones should be done to exclude causes that are not secondary to the bypass procedure itself. We present a patient 13 years post JI bypass with recurring renal calculi due to primary hyperparathyroidism.
