RECURRENT hematuria in the pediatric age group presents a problem with varying prognostic implications. Although recurrent hematuria in the pediatric patient is usually a manifestation of diseases that carry serious prognoses, we have encountered a group of patients in whom this symptom has a benign course and was not apparently associated with any of the known pathogenic etiologies.
Gross hematuria may recur during the recovery period following acute glomerulonephritis of group A streptococcal etiology. Recurrent hematuria in this disease may be precipitated by streptococcal as well as nonstreptococcal upper respiratory infections.1 Such recurrences are limited in number and occur within a few months after the initial attack of acute glomerulonephritis. The good prognosis associated with group A streptococcal acute glomerulonephritis is not necessarily altered by these recurrences. However, the persistence of hematuria over a prolonged period of time should raise the possibility that one is dealing with acute exacerbations of
