980 Etiology of Acute Pyelonephritis and Correlation of Clinical and Analytical Parameters

Background and aims: Urinary tract infections (UTIs) are relatively common infections in children. Findings on nuclear renal scans suggest that the vast majority of infants and young children with febrile UTIs have acute pyelonephritis (APN, upper-tract infection). Early recognition and prompt treatment of UTIs is important to prevent late sequelae, such as renal scarring, hypertension, and renal failure. When assessing the pediatric patient with UTI, one may encounter few specific symptoms. Febrile UTI should be assumed to be pyelonephritis and treated accordingly. The aims of this study are determine prevalence of APN in our department, characterize etiologic agents of APN and establish correlation between clinical and analytical parameters.
