Circadian Excretion of Uric Acid on Condition of Standard Diet after Purine Load in Calcium Oxalate Stone-Formers and Healthy Controls

Protein-rich nutrition after World War II shows a correlation with an increase of urolithiasis. Considerable significance is seen in the elevation of uric acid in serum and the increased excretion of uric acid in urine. Therefore, we studied the metabolism of uric acid in healthy controls and calcium oxalate stone-formers before and after an oral load with purines.
