RESUMO
OBJECTIVES: To determine the frequency of urinary system anomaly in children aged 0-18 y suffering from first urinary tract infection (UTI) and to establish which age group requires urinary ultrasonography (USG) screening. METHODS: Age and gender, urine culture, urinary USG, and urological imaging results among 247 children in the 0-18 y age group with a first diagnosis of UTI were investigated retrospectively. RESULTS: Anomaly was detected at USG in 68 (27.5%) of the 247 patients suffering from first UTI. The most common anomaly was hydronephrosis. Non-E. coli micro-organisms were the pathogenic agents in 61.8% of patients with anomalies detected at USG. Being in the 0-5 y age group (OR: 0.524, 95% CI 0.284-0.970, p = 0.040) and presence of atypical UTI (OR: 4.746, 95% CI: 1.675-13.450, p = 0.003) emerged as independent predictive markers of severe urinary system pathologies on multiple regression analysis. CONCLUSION: Based on the data in the present study, routine USG screening is recommended for children suffering from first UTI under the age of 5 y and for the children suffering from atypical UTI at all ages.
