[Hypo-uricemia due to renal uricosuria (author's transl)].

A 49 years old healthy man was found to have major hypouricemia (0.2--0.5 mg/100 ml) with normal 24 hours urinary urate excretion (300 mg). The urinary clearance of uric acid was found to be very increased (100 ml/mn), higher than the clearance of creatinine (85 ml/mn). Urinary xanthine and hypoxanthine levels were normal. There was no other clinic or biologic trouble.
