Urinary citrate excretion was measured with a specific enzymatic technique in normal subjects and in an unselected group of patients with recurrent calcium oxalate stones. Hypocitraturia (citrate levels less than those present in 95 per cent of the normal population) was detected in 7 of 46 patients with stones (15 per cent). Hypocitraturia was the only metabolic abnormality in 6 patients.
采用特定酶学技术对正常受试者及一组未经挑选的复发性草酸钙结石患者测定尿枸橼酸盐排泄量。在46例结石患者中，有7例（15%）检测到低枸橼酸盐尿症（枸橼酸盐水平低于95%正常人群）。6例患者中，低枸橼酸盐尿症是唯一的代谢异常。
