[Genetic aspects of primary hyperoxaluria: epidemiology, ethiology, pathogenesis, and clinical signs of the disorder].

Primary hyperoxaluria is a group of rare inherited diseases characterized by impaired oxalate metabolism with the early manifestation of urolithiasis and the development of the chronic kidney disease. The mutations in the AGXT, GRHPR, HOGA1 genes are attributable for different types of primary hyperoxaluria leading to the dysfunction of specific enzymes involved in the oxalate metabolism. The article summary the current data on the epidemiology, genetic and biochemical aspects of pathogenesis of the primary hyperoxaluria types 1-3.

[The role of urinary tract infection in the development of recurrent nephrolithiasis].

This is a literature review on the role of microbial flora in the development of recurrent urolithiasis. The authors outline pathogenetic aspects of recurrent stone formation associated bacterial flora. A number of studies reported that standard urine culture has limited sensitivity in detecting urinary tract infection.
