Abstract
Primary hyperparathyroidism (PHPT) is known as a rare cause of acute pancreatitis. We report on the case of a 21-year-old male with PHPT. To our knowledge, this is the first report of PHPT which simultaneously caused severe acute pancreatitis (AP) and ureteral stones (US). The patient was admitted to our hospital with AP and US complicating hypercalcemia. He presented with severe circulatory shock and multiple organ failure requiring mechanical ventilation and continuous hemodiafiltration. He was diagnosed as having PHPT and suffered from refractory hypercalcemia, but it was successfully controlled by the administration of bisphosphonate. He was successfully weaned from mechanical ventilation and continuous hemodiafiltration, and discharged from the ICU on the 24th ICU day. Thereafter he underwent a parathyroidectomy and transurethral ureterolithotripsy.
