Bacterial identification, antimicrobial susceptibility testing, and multidrug resistance (MDR) classification followed standardized techniques. Bacteria with a frequency of less than 2% were excluded. Statistical analysis was performed using R software, with the chi-square test applied and significance set at p < 0.05.Results: Of 4060 urine samples collected, 892 (22.0%) had positive results for common infections. Gram-negative bacteria predominated (591/892; 66.3%), with Escherichia coli being the most prevalent (336/892; 37.7%). Enterococcus spp. (152/892; 17.0%) was the leading Gram-positive pathogen. Some antibiotics had significant resistance rates, especially in Gram-negative bacteria, with ampicillin having the greatest resistance rate (92.8%). Carbapenems and nitrofurantoin remained generally effective. Among Gram-positive bacteria, high resistance was seen for macrolides ranging from 85.5% (azithromycin) to 89.8% (erythromycin), and for tetracyclines, ranging from 0% (teicoplanin) to 85.2% (tetracycline). There was no resistance to tigecycline and teicoplanin, indicating their potential efficacy against multidrug resistance (MDR) bacteria causing UTIs. MDR rates were higher in Gram-negative bacteria (64.8% versus 43.5%), with Klebsiella pneumoniae having the highest rate (78.7%).Conclusion: This study underscores the urgent need for ongoing surveillance of AMR patterns in Vietnam and emphasizes the significance of efficient infection prevention methods, prudent use of antibiotics, and targeted interventions to combat antimicrobial resistance.Keywords: urinary tract infections, UTIs, antimicrobial resistance, multidrug resistance, MDR, Vietnam
