A urinary tract infection (UTI) is a very common disease and can occur at any age. The vast majority of UTIs is caused by enteric bacteria. The study aimed to identify the etiologic agents most frequently, the profile of antibiotic susceptibility and the factors possibly associated to the UTIs recurrents in women older than 15 years, cared for and / or admitted to the Hospital of the University of Goias. From March to November 2009, were invited and accepted to participate in the study 923 women in this age group and they were interviewed using a questionnaire about demographics data and risk factors for recurrent infections. Escherichia coli was the most frequent agent accounting for 67.9% of the total, followed by Enterobacter sp (6.2%), Klebsiella sp (6.2%), Proteus mirabilis (4.5%), Morganella morganii (4.0 %), Acinetobacter baumannii (2.8%) and Staphylococcus aureus (2.2%). %). E. coli showed higher rates of resistance to ampicillin in 46.7% patients with recurrent infection and 50.0% in infections nonrecurring; amoxicillin/clavulanate (32.6% and 35.7%), trimethoprim-sulfamethoxazole (30,0 and 25,0%, respectively) and 100,0% susceptibility to imipenem and nitrofurantoin in both groups. Enterobacter sp showed greater resistance to ampicillin, amoxicillin/clavulanic, norfloxacin and gentamicin (>88.0%) and greater susceptibility to amikacin, cefepime, imipinem and cephalosporins. Klebsiella sp showed high resistance to ampicillin and amoxicillin / clavulanate (> 60.0%) and greater susceptibility to quinolones (> 60.0%), amikacin and imipenem (100.0%) in both groups. There were no statistically significant differences between the risk for recurrent infection or not assessed for menopause, hypertension, hysterectomy, SEL (Systemic Erythematosus Lupus) and smoking. The only risk factor associated to recurrent infection in patients older than 50 years with diabetes. In this study, there was a greater number of E. coli in UTIs, followed by other enterobacteria such as Enterobacter sp and Klebsiella sp. Among all drugs tested, all the micro-organisms, were resistant generally to penicillins, being the most effective quinolones and carbapenems.
