[Endoscopic therapy of ectopic ureterocele].

For a long time the standard treatment of an ectopic ureterocele, combined with a double collection system, was an upper-pole resection with or without ureter resection. Between 1980 and 1992, 27 children were treated initially with an endoscopic incision of the ureterocele. Twenty-four of these children were followed up. In 11 of 24 cases the endoscopic incision was sufficient and in 5 of 24 other children a reflux operation had to be performed afterwards, so that in 66% of the children the upper-pole resection was not necessary. We presume that the endoscopic incision of an ectopic ureterocele must be the first step in operative planning.
