title: The surgical management of megaureters in duplex systems: the efficacy of ureteral tapering and common sheath reimplantation.
abstract: We describe 6 children with renal duplication associated with megaureter(s) who underwent ureteral tapering and common sheath reimplantation. Of the patients 4 had complete duplication with reflux into 1 or both ureters and 2 had incomplete duplication with a short distal segment that was obstructed at the ureterovesical junction. All obstructed or refluxing ureteral segments were dilated to a degree that tapering was required at the time of common sheath reimplantation. Megaureter repair in the presence of a duplicate collecting system proved to be safe and reliable.
