Background and Objective: Urinary tract infections lead to increased hospitalization, direct patient costs, and mortality. Data on the prevalence of common uropathogens and antimicrobial (AM) susceptibility pattern are sparse and it varies geographically. Our aim was to determine AM resistance patterns in a tertiary urological center. Materials and Methods: Data on bacterial uropathogens and AM susceptibility between January 2015 and January 2016 in 1080 significant bacterial isolates were analyzed. Results: The most commonly isolated bacteria were Escherichia coli in 720 (66.6%), Klebsiella species in 170 (15.7%), and Pseudomonas aeruginosa in 80 (7.4%) patients. E. coli from inpatients was susceptible to imipenem (260; 97%), amikacin (212; 79%), piperacillin–tazobactam (206; 77%), nitrofurantoin (198; 73%), and cefoperazone–sulbactam (206; 77%). Klebsiella isolates were sensitive only to imipenem, piperacillin–tazobactam, and cefoperazone–sulbactam. Pseudomonas and Proteus species were sensitive only to imipenem and piperacillin–tazobactam. In outpatients, the common uropathogens showed lesser resistance only to nitrofurantoin (15%–47%). Conclusions: E. coli and Klebsiella are the most common uropathogens. Nitrofurantoin should be the drug of choice in outpatients. In inpatients, beta-lactamase inhibitors and amikacin have good AM sensitivity. Carbapenems should be the first choice AM agents in the intensive care unit.
