title: Macroscopic hematuria secondary to hypercalciuria and hyperuricosuria.
abstract: An adult presenting with asymptomatic gross hematuria attributable to hypercalciuria and hyperuricosuria is described. Extensive evaluations for other causes of hematuria were negative, and the gross hematuria resolved with treatment of the hypercalciuria and hyperuricosuria. Hematuria commonly attributable to these metabolic causes in children may also occur in adults. A 24-hour urine collection for the measurement of calcium and uric acid excretion in adults without nephrolithiasis may play an important role in the evaluation of hematuria.
