Objective: Determine the epidemiological behavior of the Urinary Tract Infections and the changes in sensibility and antibiotic resistance of Escherichia coli in the Hospital Universidad del Norte, Soledad, Atlántico. January 2005 to december 2006. Materials and methods: There was realized a descriptive study of retrospective type, with a sample of 537 cultures of the patients who consult at Hospital Universidad del Norte. The cultures were evaluated across the colonies forming units (CFU) and then the antibiograms’ reports were analyzed, annotating the information for resistance, antibiotic sensibility and evaluating the epidemiological behavior of the principal antibiotics used in the clinical practice at this institution. Results: The percentage distribution of Urinary Tract Infection f (UTI) found in 2005 in women: 72.9 %, men: 27.1 %, and in 2006, women: 73.8 %, men: 26.2 %. The most frecuent microorganisms in 2005 were Escherichia coli (66.24 %), Klebsiella (10.63 %) and for 2006: Escherichia coli (85 %), Proteus (5.29 %). The major rates of antibiotic resistance of the Escherichia coli in 2005 was: ampicilina, trimetoprim sulfa and ciprofloxacina. In 2006 the behavior was similar, but decrease is observed in the resistance to fluoroquinolonas; the major rates of sensibility in 2005 include nitrofurantoína, ampicilina/sulbactam and aminoglucosidos in relation to 2006, in which decrease is observed in the sensibility to the first and the second one. Conclusion: The percentage distribution shows that UTI is more frequent in women. The causal microorganism of most of UTI’s cases is Escherichia coli. Decrease was demonstrated in the rates of resistance to ampicilina, trimetoprim sulfametaxol, first generation cefalosporines and ciprofloxacina in 2006 with relation to 2005.
