A urinary tract infections (UTI) is an infection that affects the urinary tract caused by bacteria (most often Escherichia coli). Antimicrobial are used to treat UTI. The sensitivity of bacterial pattern toward antimicrobials and the bacterials pattern will affect the effectiveness of UTI treatment. This research was conducted to evaluate the strains of bacterial and sensitivity of bacterial pattern that caused UTI. A descriptive evaluation and retrospective study was done in this research. In total 79 cases patient with UTI at Inpatient Unit “X” hospital in Yogyakarta 2011, whose has sensitivity test and sprout up germ culture examination data were included. Patient with UTI at Inpatient Unit which has barren germ culture data and sprout up germ were excluded. The common microbes were gram negative bacteria including Escherichia col, Pseudomonas aeruginosa, Klebsiella pneumonia, and Staphylococcus coagulase negative. Gram negative microbes were sensitive to amikasin, imipenem, netilmicin, and fosfomicin. Gram positive microbes were sensitive to nitrofurantoin, vancomicin, imipenem and cefuroxime.
