有人报告因炎症性肠道疾病行回肠切除术或肥胖症患者行小肠捷径手术后,其肾脏形成草酸钙结石。这些患者的尿中草酸排泄量增加,原因是大肠吸收草酸增加。由于胆汁酸缺乏,引起脂肪吸收不良,长链脂肪酸与钙相结合,使得不能与钙结合且易吸收的草酸增加,草酸的吸收是被动的,大量草酸被吸收经尿排泄。此外脂肪酸和胆汁不被吸收到大肠,大肠对草酸的通透性增加,因此明确了肠性草酸尿症
It was reported that due to inflammatory bowel disease in patients undergoing ileal resection or obesity short cut surgery, the kidneys to form calcium oxalate stones. Urinary oxalate excretion increased in these patients due to the increased absorption of oxalic acid in the large intestine. Due to lack of bile acid, fat absorption caused bad, long-chain fatty acids and calcium combination, making calcium and not easy to absorb and absorption of oxalic acid increased oxalic acid absorption is passive, a lot of oxalic acid is absorbed through the urine excretion. In addition, fatty acids and bile are not absorbed into the large intestine, and the permeability of the large intestine to oxalic acid is increased, thereby clarifying intestinal oxalic aciduria
