Abstract

Objectives: To analyze microbial etiology and associated factors in complicated urinary tract infections (cUTI). Methods: A retrospective, cross-sectional descriptive study was conducted on 622 cUTI patients at the Rehabilitation Centre, Bach Mai Hospital (2019 - 2023). Results: The median age was 57 years; males accounted for 60.6%. Common risk factors for cUTI included neurogenic bladder (82%) and catheterization (74%). The main pathogens were E. coli (45.8%), K. pneumoniae (16.4%), and E. faecalis (6.8%). The microbial patterns were stable but increasingly diverse, associated with gender and urinary obstruction. Conclusion: E. coli and K. pneumoniae are the two predominant Gram-negative pathogens, while E. faecalis was the most frequent among Gram-positive bacteria. Key factors related to cUTI include neurogenic bladder, male gender, and catheterization. Continuous monitoring of microbiology and adherence to antibiotic treatment guidelines are essential to improve therapeutic outcomes and reduce antimicrobial resistance.
