[Structure of microorganism species cultured from urine of urolithiasis patients].

AIM: To investigate the incidence of microorganisms of different taxonomic groups and their associations in the pelvic and bladder urine of adult urolithiasis patients.

MATERIALS AND METHODS: A bacteriological method and metagenomic sequencing were used to investigate the bacterial spectrum of microflora cultured from pelvic and bladder urine sampled during surgical interventions in urolithiasis patients.

RESULTS: The both microbiotas had approximately the same spectrum, but in 26.1% of patients it was inconsistent. Metagenomic analysis detected DNA of microorganisms in urine samples which were found free of microflora by the bacteriological method.

CONCLUSION: The study findings showed species diversity of microorganisms cultured from pelvic and bladder urine sampled during surgical interventions in urolithiasis patients.
