Abstract

In order to examine the effect of diet on the urinary excretion of oxalate, a spinach loading and milk loading experiment was performed in normal subjects and patients with single calcium oxalate stones and recurrent calcium oxalate stones after a rat experiment. When spinach (100 g, total oxalate 642.57 mg, insoluble oxalate 282.21 mg, taken oxalate 444.57 mg) was given with a low calcium diet to the patients, the increase of urinary oxalate was more prominent in those with recurrent stones; the mean urinary oxalate increased from 39.84 to 84.18 mg/day (P less than 0.01) in the group with recurrent stones, from 36.95 to 55.12 mg/day (P less than 0.05) in the group with single stones and from 33.99 to 42.78 mg/day in the control group. These increases in oxalate excretion could be ameliorated by the concurrent oral administration of milk (calcium 343 mg). Moreover, diurnal variation in oxalate excretion was observed. It was more evident under spinach load in the group with recurrent stones than in the control group. Urinary oxalate increased promptly, reaching peak levels between 4 and 6 hours after loading in the group with recurrent stones and single stones, and between 2 and 4 hours in the control group. The influence of the spinach load disappeared within 24 hours.
