Abstract

We encountered a case of renal hypouricemia and absorptive hypercalciuria. Although renal hypouricemia is asymptomatic as usual, it is rarely complicated with acute renal failure and urolithiasis. A 43-year-old man had hypouricemia (serum uric acid, 0.6-1.0mg/dl) with an increased renal uric acid clearance (69.4ml/min), hypercalciuria (367.2mg/day). In present case, there was no response of uric acid excretion to either pyrazinamide or probenecid and hypercalciuria disappeared after calcium restriction diet. These results suggest that the present case had the defect of both pre-and postsecretory reabsorption of uric acid and absorptive hypercalciuria.
