Distribution of pathogens causing urinary tract infection in patients with urinary calculi. A. The number of pathogenic bacteria detected from 2015 to 2019. The total detection rate of pathogenic bacteria peaked in 2017 and then returned to previous levels. B. Distribution of pathogenic bacteria within 5 years. A total of 344 Gram-negative, 46 Gram-positive, and 17 fungus strains were isolated, and Gram-negative bacteria were the main pathogens (84.52%) of urinary calculi complicated with urinary tract infection.
