title: [Long-term non-malformative urinary infections in children. (I)].
abstract: Non malformative long term urinary tract infections affect above all the female sex. The specific anatomic conditions explain only in part the predisposition for the female sex. Other determinants are the individual susceptibility and bacterial virulence. The authors studied 169 pediatric patients with recurrent urinary tract infections; of which 159 where females. The study of the blood group in 70 patients showed a net predominance of the groups B and AB. About one-third of the patients studied presented a scarce symptomatology or complete absence. The urodynamic study in 120 patients has revealed an abnormal pattern in more than 80% of the cases. According to the authors the abnormal urodynamic pattern is related to the long-term infection and is reversible in the cases which are curable. In about one-third of the cases with long-term infections which are resistent to the therapy, the cystoscopy has revealed a cystitis cystica. The study carried out by the authors permits precise indications on the specific tests that must be effectuated in this particular type of pathology and the indications of treatment.
