Objective: To analyze the etiological agents of urinary tract infections (UTIs) and their antimicrobial resistance patterns at Vinmec Can Tho International General Hospital.
Subjects and methods: This was a prospective cross-sectional descriptive study including 37 patients diagnosed with UTIs who were examined and treated at the Urology Outpatient Clinic of Vinmec Can Tho International General Hospital from June 2025 to March 2026.
Results: The mean age was 47.4 ± 16.2 years (range: 20–82 years). Female patients accounted for 89.2%. There were 2 cases of co-infection (both involving Escherichia coli) and 1 case of fungal infection caused by Candida glabrata. Among bacterial pathogens, Escherichia coli was the most common (48.7%), followed by Staphylococcus haemolyticus (10.3%) and Enterococcus faecalis (10.3%). The rate of ESBL-producing Escherichia coli was 52.6%, and carbapenem resistance was 10.5% (to meropenem and ertapenem). All Staphylococcus haemolyticus isolates (4 strains) were methicillin-resistant (MR), while remaining 100% susceptible to vancomycin, linezolid, and nitrofurantoin. All Enterococcus faecalis isolates (4 strains) were 100% susceptible to ampicillin, vancomycin, linezolid, and nitrofurantoin.
Conclusion: The leading causative agent of UTIs at Vinmec Can Tho International General Hospital was Escherichia coli (48.7%). A high rate of antimicrobial resistance was observed in Escherichia coli, including resistance to third-generation cephalosporins (52.6%) and quinolones (42.1%), with an ESBL production rate of 52.6%. Gram-positive bacteria (Staphylococcus, Enterococcus) remained highly susceptible to vancomycin, linezolid, and nitrofurantoin.
