Acute uncomplicated cystitis is the most common urinary tract infection that mainly occurs in adult females, particularly sexually active young women and postmenopausal women. It is commonly observed in primary health care settings, including urology as well as obstetrics and gynecology; more than half of healthy adult women visit clinics and hospitals at least once in their lifetime due to acute uncomplicated cystitis. The most common bacterium causing this condition is Escherichia coli, followed by Staphylococcus saprophyticus, Klebsiella pneumoniae, Proteus mirabilis, and etc. Trimethoprim-sulfamethoxazole or fluoroquinolones have been used as an empirical antibiotic treatment. However, as fluoroquinolone-resistant organisms or extended spectrum beta-lactamase-producing organisms are becoming more prevalent worldwide, information on regional antibiotic resistance and guidelines on antibiotic use are becoming increasingly more desparate.
