Purpose: We investigated recent aspects of causative organism and antimicrobial susceptibility of urinary tract infections(UTI). Materials and Methods: We retrospectively analysed 735 uropathogens, and their antimicrobial susceptibility in 479 patients of one general hospital between January 2010 and December 2011. Causative organisms and antimicrobial sensitivities according to sex, age and admission year were analyzed using descriptive statistics. Result: The incidence of UTI shows peaks in the 7th decade(31.1%). The common pathogens were E.coli(41.7%), Klebsiella(12.4%), Staphylococcus(12.2%), Enterococcus(9.8%) and Pseudomonas(7.8%). The incidence of gram positive organisms were increased from 23.0% in 2010 to 29.4% by 2011. For the gram negative isolates, amikacin and imipenem showed relatively higher sensitivity, while cephalothin, ceftazidime and piperacillin/tazobactam showed relatively lower sensitivity. For the gram positive isolates, teicoplanin and vancomycin showed relatively higher sensitivity, while clindamycin and ciprofloxacin showed relatively lower sensitivity. Conclusions: In this study, causative organism and antimicrobial sensitivity of UTI were investigated. These results may help to treat the patients with UTI. Further larger study considering clinical aspects of UTI patient is needed.
