[Therapeutic concept of complicated ureterocele in childhood].

Because of the varied pathological manifestations of complicated ureteroceles, it is difficult to formulate a standardized management schedule. In a retrospective analysis of the methods of treatment appued in recent years, we try to determine the best procedure. Incision of the ureterocele is obsolete. Ureteroceles are often combined with renal duplication. Therefore, in small children we prefer staged surgical management with primary heminephrectomy and partial ureterectomy, with the option of avoiding later excision of the ureterocele. In older children it is advisable to perform all the treatment of the urinary tract in a single stage.
