The possible roles of the diet and of intestinal absorption in the increased excretion of oxalate by patients with renal calcium stones have been studied. 2. Dietary surveys showed that the mean daily intake of oxalic acid by stone-formers was not significantly different from that of non-stone-formers. 3. The mean urinary excretion of oxalate, expressed as an oxalate/creatinine molar ratio, was significantly reduced by fasting, the change being more marked in the stone-formers than in the normal subjects. Moreover, fasting abolished the difference in mean oxalate/creatinine ratios between stone-formers and control subjects. 4. These results are compatible with the hypothesis that the small increases in urinary oxalate excretion which occur in some idiopathic calcium oxalate stone-formers are due to increased absorption of oxalate from the intestine, which may be due to a reduction in intraluminal calcium concentration.

已对饮食和肠道吸收在肾钙结石患者草酸盐排泄增加中可能发挥的作用进行了研究。2. 饮食调查表明，结石形成者每日草酸的平均摄入量与非结石形成者相比无显著差异。3. 以草酸盐/肌酐摩尔比表示的草酸盐平均尿排泄量在禁食时显著降低，结石形成者的变化比正常受试者更明显。此外，禁食消除了结石形成者与对照受试者之间草酸盐/肌酐平均比值的差异。4. 这些结果与以下假设相符：一些特发性草酸钙结石形成者尿草酸盐排泄量的小幅增加是由于肠道对草酸盐的吸收增加，这可能是由于管腔内钙浓度降低所致。
