OBJECTIVES: to determine the microorganisms mostfrequently found in urocultures after urinary catheterization and their antibiotic sensitivities in women undergoing elective gynecological surgery. METHODS: the study was carried out at theInstituto de Medicina Integral Professor FernandoFigueira, IMIP, in Recife, Pernambuco, Brazil, between January and May 2007. Urine cultures wereobtained from these patients on two occasions subsequent to the removal of the catheter: within the first 24h and 710 days later. RESULTS: urine samples were collected from 249 women. 23.6% (n=46) of the samples collected in the first 24h were found to have urine cultures and 11.1% (n=25) of those collected 710 days after removal of the catheter. No significant difference was observed regarding the microorganisms present in the uroculture, when comparing the two periods of sample collection. Klebsiella spp. was the most frequentmicroorganism found (first 24h=47.8% vs. 7/10 days=44.0%; p=0.76), followed by Escherichia coli, and other Gram negatives. The antibiotics, amicacine, cefepime, ciprofloxacin, meropenem andticarcilinclavulanate showed sensitivity equal to orgreater than 75% for the main microorganism isolated. CONCLUSIONS: Klebsiella spp. was the most frequent microorganism present in urocultures after urinary catheterization in women undergoing elective gynecological surgery. Ciprofloxacin was found to have a sensitivity of 95%.
