Genitourinary tract anomalies in Thai children with urinary tract infection.

One hundred and forty-three pediatric patients with initial documented UTI were analysed retrospectively. E. coli was the most common organism found in uncomplicated cases. Forty-six per cent of 110 patients who had radiologic evaluation had genitourinary tract anomaly with higher frequency in boys during the infancy period and girls during the early childhood period. Primary VUR was found in 11 per cent of patients mainly in infancy with an equal number among boys and girls. We conclude and strongly advise that radiologic evaluation should be done in all children with UTI, especially if they are younger than 5 year old.
