Endoscopic Treatment with Deflux® for Refluxing Duplex Systems

Abstract Purpose: The aim of this study was to review the experience of a single institution with the endoscopic Deflux® (Q-Med Scandinavia, Uppsala, Sweden) procedure and assess its effectiveness in the treatment of refluxing duplex systems. Materials and Methods: A retrospective review of all patients that underwent endoscopic Deflux treatment for vesicoureteral reflux (VUR) in duplex systems between June 2003 and July 2007 was performed. Data collection included: age, gender, side of refluxing ureter, preoperative radiologic grade of VUR on a voiding cystourethrogram (VCUG), presence of VUR on a radionuclide VCUG 3 months postprocedure, volume of Deflux injected, number of Deflux injections performed per patient, and number of patients that underwent reimplantation surgery. Results: Sixteen patients with duplex systems, two being bilateral, for a total of 18 duplex ureteral systems, underwent the Deflux procedure. Grades of reflux were as follows: grade II: 4 ureters; grade III: 8 ureters; grade IV: 4 ...
