[Oxalobacter formigenes - use of the colon microbiome in the prevention of kidney stones].

The number of calcium oxalate urolithiasis is increasing every year, especially in highly developed countries. The most common causes of precipitation are hyperoxaluria and hypercalciuria. The reason for increased oxalate excretion may be genetic defects of hepatic enzymes (primary hyperoxaluria), disturbances in metabolism or absorption of oxalate and changes in the composition of the intestinal microflora in the form of deficiency of oxalate metabolizing bacteria e.g. Oxalobacter formigenes. This bacterium has been the scientific focus of attention in recent years due to numerous reports on its impact on the reduction of oxaluria, resulting in a decreased recurrence risk of calcium oxalate stones by up to 70%. In recent years, attempts have been made to create a probiotic drug, the main element of which is O. formigenes.
