ABSTRACT Background and Objectives: Catheter-associated urinary tract infections (CAUTIs) represent the most frequent nosocomial infections, accounting for 80% of all UTIs in healthcare settings. Common causative pathogens include Klebsiella spp., Escherichia coli, Staphylococcus aureus, Enterococcus spp., and Pseudomonas aeruginosa. This study aims to identify uropathogens associated with CAUTIs in ICU patients at Aswan University Hospital to guide empirical therapy and enhance infection prevention strategies. Methods: A total of 200 patients with indwelling Foley catheters in the ICU at Aswan University Hospital were enrolled between June 2023 and June 2024. Urine samples were collected 48 hours post catheterization, processed under sterile conditions, and cultured using standard microbiological techniques. Results: Klebsiella pneumoniae was the most frequently isolated pathogen (39%), followed by E. coli (33%), Staphylococcus aureus (13%), Coagulase-negative staphylococci (3%), Enterococcus spp. (4%), Serratia spp. (2%), and Pseudomonas aeruginosa (1%). CAUTIs were more prevalent among females and patients aged 30-39 and 60-69 years. Conclusion: CAUTIs remain a significant source of morbidity and healthcare costs. Klebsiella pneumoniae and E. coli are the leading pathogens. Effective CAUTI prevention requires catheter management strategies, reducing catheter duration, and enhancing infection control practices.
