Comparison of the Voiding Cystourethrogram Results One and Three weeks after the First Urinary Tract Infection in 1-Month to 15-Year-Old Children

To determine whether the timing of voiding cystoureterogram (VCUG) in the first or the third week after a diagnosis of urinary tract infection (UTI) is important in the diagnosis and severity of VUR. Materials and Methods: In this case-control study, 72 children between 1 month and 15 years old diagnosed with their first episode of UTI were investigated over one year. The study population was divided into 2 groups of 36, early (VCUG in the first week after UTI) and late (VCUG 3 weeks after UTI), and compared the severity and incidence of reflux in both groups. Results: The prevalence of VUR was 66.6%. Twenty-two cases in the first group (61%) and 26 cases in the second group (72.2%) presented with VUR. The peak age of the disease in both groups was 1-3 years with a female predominance. The most common germ detected was E-Coli and the most common presentations were fever (87.5%) and dysuria (26.3%). Conclusions: As VUR following UTI is very common in children and is one of the most important risk factors of early hypertension and chronic renal failure, early diagnosis by VCUG seems to be useful in all UTI patients before discharge.
