BACKGROUND: Urinary tract infections (UTI) are gaining a new role of importance in nosocomial infections. The main reason for this increase is the huge number of chronic catheterized patients (corresponding to 80% of all UTI). OBJECTIVES: Analysis of the frequency and antimicrobial susceptibilities to urinary tract infections agents in chronic catheterized patients in outpatient setting. METHOD: Urine cultures of 109 patients mentioned above were analyzed and if positive, it was collected the patient conditions that leads to UTI, the causative agents and the antimicrobial susceptibilities. RESULTS: From the 858 urine cultures analyzed from 109 patients, 674 (78.57%) were positive for pathogens growth. The most common microorganisms found were the Gram-negative bacilli with 618 (92.38%) cultures in which Pseudomonas aeruginosa was found in 288 (42.77%) of them, followed by Escherichia coli with 89 (13.14%) cultures, antibiotic susceptibilities to norfloxacin was 40%-44.34% and to ciprofloxacin was 35.13%-51.37%, main choice to oral treatment. The main predisposed condition for the infection in these patients was: time of catheterization, age and diagnosis. DISCUSSION: In this study, it was determined that conditions predisposed towards UTI are fundamental for orientation, medical treatment and care in the catheterization. The data collection showed that 674 (78.57%) of these patients had infections, with great incidence in the first and second years. CONCLUSION: The non-fermentative Gram-negative bacilli were the most common agents that differentiate them from the infections within the community in which the most frequent agent is Escherichia coli (which was the second agent in this study).
