ABSTRACT
Calcium oxalate (CaOx) stone is the main type, and its formation is closely related to the metabolism of oxalic acid and calcium. Gut Microbiome is normal microflora which settled in the human intestinal tract and plays an important role in regulating a variety of metabolism in the body. In the past, Oxalobacter formigenes in gut was a protective factor for the formation of CaOx stones. Recently, it has been found that the bacteria regulating oxalate metabolism were not limited to Oxalobacter formigenes. Gut Microbiome of CaOx stones formers is different from healthy people. It regulates the metabolism of oxalic acid in the body through the gut-kidney axis and affect the formation of CaOx stone. The purpose of this study is to describe the characteristics of intestinal flora in patients with CaOx stones, and to summarize its potential function in the formation of CaOx stones and its possible clinical application in the future.
