草酸是尿路结石的主要成分之一,三分之二以上的结石是纯草酸钙或是以草酸钙为主要成分构成的。故了解草酸的代谢异常对防治尿路结石有重要意义。肠原性高草酸尿症是消化系疾病引起的一种尿草酸排泄量异常增多的综合征。24小时尿草酸排泄量可与原发性高草酸尿症一样高达数百毫克(正常为10～55mg/24小时尿),它是获得性高草酸尿症的一种类型,临床上并不罕见,若不处理可致肾结石及肾功能损害等。这是近十年来在草酸代谢研究方面取得的
Oxalic acid is one of the main components of urinary tract stones. More than two thirds of the stones are pure calcium oxalate or calcium oxalate as the main component. It is important to understand the metabolic abnormalities of oxalic acid on the prevention and treatment of urinary tract stones. Enteric-induced hyperoxaluria is a syndrome of an abnormal increase in urinary oxalate excretion caused by digestive diseases. 24-hour urinary oxalate excretion can be as high as a few hundred milligrams (normally 10 to 55 mg / 24 hours of urinary) of primary hyperoxaluria and is a type of acquired hyperoxaluria clinically not uncommon , If not treated can cause kidney stones and kidney damage. This is the past decade in the field of oxalic acid metabolism
