The current study aims to determine the prevalence of urinary tract infection (UTI) and the need to perform urine analysis and cultures in children admitted with bronchiolitis in a large tertiary children's hospital in Riyadh, Saudi Arabia. MethodsWe conducted a retrospective chart review of pediatric patients 0-2 years of age who were admitted with bronchiolitis from November 2016 till April 2017. All charts were analyzed to identify the children investigated for UTI, and their results were then reviewed. ResultsThere were 407 children admitted with bronchiolitis during the study period. Two-thirds of them were investigated for UTI. Only 2.6% of the patients tested positive for urine culture, and only 0.96% were found to have a true UTI. ConclusionThe prevalence of UTI in children with bronchiolitis is too low to justify routine screening. Therefore, only children with a high risk of having UTI should be investigated.
