Urolithiasis and primary parathyroid adenoma: report of one case.
A 12-year-old girl was admitted to ward because of persistent left flank pain, vomiting, and hematuria. A stone was located at the ureteropelvic junction of the left kidney, as determined by means of abdominal sonography. Metabolic investigation for a renal stone revealed that she had hypercalcemia, hypophosphatemia, and hypercalciuria. Hyperparathyroidism was diagnosed based on the hypercalcemia and inappropriately elevated serum parathyroid hormone level. A parathyroid adenoma was successfully diagnosed by using thallium/technetium subtraction parathyroid scanning. Extracorporeal shock wave lithotripsy was performed to treat the renal stone, and the parathyroid adenoma was successfully removed. The patient's postoperative course was uneventful. This case is presented because urolithiasis and hyperparathyroidism are rare in children. Metabolic evaluation is mandatory in children with a renal stone. Further investigation for the hyperparathyroidism should be performed if hypercalcemia associated with hypercalciuria is documented.
