Abstract
A case is reported of a large ureterocele associated with a single collecting system. The ureterocele caused frequent urinary retention and it was treated successfully by a staged endoscopic procedure, consisting of complete transurethral resection of the ureterocele followed by perimeatal polytetrafluoroethylene (Teflon) paste injections to prevent subsequent vesicoureteral reflux. This new approach of a combination of 2 endoscopic techniques proved to be useful in this case.
