[Recurrent bacteriuria in children].

Fifty-four children admitted to the Children's Hospital of Cordoba City with recurrent bacteriuria were followed for 12 to 97 months. Most of them were females and Escherichia coli was the most frequent microorganism isolated in recurrent attacks of bacteriuria. Ninety percent of the patients showed urological abnormalities. Vesicoureteral reflux was the most frequent. Residual urine was considered the main cause of recurrent bacteriuria. After antibioticotherapy and surgical treatment, over one half of the patients persisted with relapses. Recurrent bacteriuria appeared more frequently in male infants with severe urologic abnormalities. Finally, three groups of patients in relation to uropathy and functional renal impairment are described and a different prognosis for each one is proposed. For this reason, each patient must have a complete urologic examination done at the onset and a carefull follow-up, carried out.
