nearly 15% to 25% of patients in general hospitals have a catheter at some time during their stay. Nosocomial UTIs up to97% is related to catheter. Type of bacteremia is usually polymicrobial which making treatment more difficult. Studies showed that in these patients, mortality of bacteremia is probable.  In order to compare prevalence of UTIs among patients with and without catheter and detecting type of bacteriuria and antibacterial resistance pattern, this study was done. 
In this cross sectional study, samples were taken between Jan 2011 to July 2011.  678 hospitalized patients in different wards of Afzali pourhospital-Kerman- Iran, were enrolled the study. E_test was used to detect pattern of  resistance to  gentamicin, nitrofurantoin, ciprofloxacin, ceftriaxon and co-trimoxazole.  SPSS16 has been used For statistical analysis. Among positive culture  samples 86% were women. E.coli in 72%, candida in 10% and staphylococcus were detected in 7% of positive cultures. 56% of detected E.coli was sensitive to gentamicin , 60% to ceftriaxine, 74% to ciprofloxacin and finally 59% was sensitive to nitrofurantoin.
As regards in this research the most sensitive antibiotics in UTIs were ciprofloxacin and ceftriaxone. Unfortunately rate of antibacterial medicine resistance was high in comparison with developed countries.  Wise selection of antibiotics at hospitals can reduce antimicrobial resistance.
