[Recurrent infection of the urinary tract in girls]

A group of 18 girls, studied in a period between 1979 and 1985 with recurrent urinary tract infections (RUTI), with at least three culture documented episodes of bacteriuria in the previous year and without radiologic evidence of urinary tract abnormality is described. Incidence was 6.1% amount a selected group of 295 girls with urinary tract infection. The period of follow-up was between 2 and 6 years (X 3.33). Symptomatology was light. No predominance of urinary symptoms were found. E. coli was the most frequent germ isolated. The number of recurrences/year/girl were significantly lower with prophylactic treatment and with years of evolution. Renal damage was not found. Vesicoureteral reflux appeared in two girls only. They had a benign course and a good prognosis. Reduction of aggressive investigation in this group of patients is proposed.
