Urinary tract infection (UTI) is one of the most common bacterial infections in childhood that delayed diagnosis and treatment can cause irreversible complications. The aim of this study was to determine the prevalence of urinary tract infection in elementary school children in Khorramabad city, Iran. In this descriptive cross-sectional study, 460 female students of elementary and secondary schools of Khorramabad city were recruited after completing a questionnaire including symptoms of infection, medical and disease history, and urine culture. Antibiotic susceptibility pattern was determined by disk diffusion method accordance with Clinical and Laboratory Standards Institute (CLSI) instructions. Statistical analysis were performed by SPSS software. Of 460 students, based on urine culture results 12 (2.6%) had urinary tract infection. Asymptomatic bacteriuria in 5 patients (1.1%) and positive culture and clinical symptoms were reported in 7 cases (1.5%). Escherichia coli (83.3%) was reported as the main cause of UTI among the tested samples. The highest antibiotic susceptibility was related to imipenem (91.6%) and ceftazidime (83.3%). The prevalence of UTI, pathogenic microbial agents and sensitivity to antibiotics in different regions and periods has a significant difference, which can be due to different health levels, constant change in incidence of germs that cause UTI and various antibiotics resistance. Because almost half of the cases of urinary tract infection are asymptomatic, screening for primary school children is necessary.
