The citric acid excretion and concentration in 24 hr urine was measured in 70 stone-formers and 16 normal subjects (controls) on normal food intake followed by 9 days on a standard diet. On days 9 and 10 on the standard diet urine was collected in 3 hr portions and citric acid and calcium was measured. From day 7 to day 10 on standard diet the authors found only a slight change in the 24-hr excretion of citric acid ('steady state'). The citric acid excretion and concentration is significantly lower in stone-formers than in healthy controls. In both groups there is a sinusoid rhythm in citric acid excretion and concentration throughout the 24 hr period. The calcium concentration is at its maximum when the citric acid concentration is at its minimum.
