Abstract

Purpose: Clinical and paraclinical characteristics of urinary tract infections in patients undergoing urinary tract intervention at the Urology and Dialysis Center of Bach Mai Hospital. Materials and methods: retrospective study combined with a cross-sectional description of 101 infected patients undergoing urinary tract intervention at the Kidney - Urology & Dialysis Center of Bach Mai Hospital from July 2022 to August 2023. Results: The average age of the study subjects was 50.98 ± 18.83 years, with 44% of patients from 46 to 65 years old. Male patients account for a higher proportion of 57%. The most common risk factor is urinary stones with 63%, the most common clinical symptoms are fever (74.26%), painful urination (53.46%), and back pain (37.62%). Urine cultures were 78% Gram-negative with the most common organism being P. aeruginosa and 22% Gram-positive with the most common organism being E. faecium. The ESBL production rate of E. coli is 60%, and K. pneumoniae is 33.33%. E. coli is also sensitive to imipenem, beta-lactam + beta-lactamase inhibitor, nitrofurantoin, and fosfomycine, and highly resistant to quinolones and cephalosporins. P. aeruginosa and K. pneumoniae are highly resistant to most common antibiotics. Conclusions: The results of the study show that urinary tract infections in patients undergoing urinary tract intervention are often complicated by bacterial agents with a high rate of ESBL secretion and multidrug resistance.
