Introduction: urinary tract infections account for 20 to 50% of infections in intensive care units, of which 92% are in catheterized patients, constituting the second or third leading cause of nosocomial infection, generating a significant impact on morbidity and mortality, and costs associated with the care process. Objective: To describe the epidemiological clinical features, and antimicrobial susceptibility in patients with urinary tract infection in hospital services Intensive Care Unit and Intermediate Care Unit of the Hospital Almanzor Aguinaga Asenjo during 2009-2014. Material and Methods: A descriptive series of cases where the medical history of each patient was reviewed with nosocomial urinary tract infection and clinical, epidemiological and antimicrobial susceptibility of positive urine cultures characteristics were identified. Results: 82 positive urine cultures were collected, 62.2% of patients had more than 60 years, the etiologic diagnosis of entering the critical area was most frequent brain vascular disease (40.2%) and more associated comorbidity was hypertension blood (45.1%). The most common organism isolated was E.coli (32.9%), the largest microbial resistance to beta-lactams (96.7%) and increased sensitivity to aminoglycosides (50.8%). Antibiotic family of third-generation cephalosporins was the most used prior to diagnosis of nosocomial urinary tract infection (56.0%). Conclusions: E. coli is the most isolated in urine cultures of nosocomial urinary tract infections microorganism, the beta-lactam resistance in critical areas is high and high sensitivity is observed aminoglycosides.
