Endoscopic correction of vesicoureteral reflux using dextranomer/hyaluronic acid copolymer (Deflux) is a widely used technique. Complications are uncommon, and ureteral obstruction occurs particularly infrequently. We present a case of delayed symptomatic partial bilateral ureteral obstruction after bilateral high-volume (>1.0 mL) Deflux injections that required surgical repair 16 months after injection (Clavien classification IIIb.) Bilateral delayed obstruction after endoscopic correction of vesicoureteral reflux has not been previously reported. Previous reports of immediate and delayed ureteral obstruction after Deflux injection are reviewed. Copyright © 2013 Elsevier Inc. All rights reserved.
