[Ureterocele: study of 66 cases observed in 60 children].

: 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.
