RESUMO
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.

Ureterocele is an unfrequent urinary malformation in pediatric age, but frequently it is clinically severe. Ureterocele in a double pyelo-ureteral system often presents very difficult treatment problems not uniformely dealt with. Authors report their experience with 66 ureteroceles observed in 60 children; more than a half of which were less than one year old. In the authors experience simple ureterocele does'nt give any surgical problem. On the contrary ectopic ureterocele, almost always associated with a pyeloureteral duplication, frequently gives some problems of surgical treatment. Treatment is always individualized but in our experience the best results have been achieved with unroofing of the ureterocele and upper heminephoureterectomy in one stage. This treatment can be used successfully in the majority of ectopic ureteroceles in pediatric age.
