Abstract

Objectives: Describe the bacterial cause of urinary tract infections (UTI) in patients assigned to undergo urine culture testing at Vinmec Times City International General Hospital from January 2020 to June 2022.
Subjects and methods: The study was conducted on 531 medical records of patients who had a urine specimen culture test and had positive results for bacteria identified as the cause of UTI during the period from January 2020 until June 2022 at Vinmec Times City International General Hospital. The study used a cross-sectional, retrospective descriptive method with data from patients' medical records.
Results: 565 bacterial strains were isolated that were identified as the cause of UTI. Of these, the Gramnegative bacteria group is 80.53%, the Gram-positive bacteria group is 19.47%. E. coli is the most isolated bacteria with 350 strains, accounting for 61.95%, followed by Enterococcus spp with 57 strains (10.09%), K. pneumoniae 38 strains (6.73%) and S. saprophyticus 24 strains (4.25%); According to age group, it shows that in each age group, E. coli is the leading cause of UTI with the highest rate compared to other bacterial causes, respectively in 3 age groups < 20, 20 - 50, > 50 age are 75%, 64.4%, 53.7%; According to gender, the rate of E. coli isolated in men is 53.4%, in women is 65% and the highest rate compared to
other common bacterial causes; In hospital departments, E. coli is still the cause with a higher proportion than other bacterial species.
Conclusions: The common bacterial causes of UTIs is Gram-negative bacteria (80.53%). E. coli is the leading bacterial cause of UTIs, accounting for 61.95%, followed by Enterococcus spp (10.09%) and K. pneumoniae (6.73%).
