Factors affecting the success of endoscopic treatment of vesicoureteral reflux and comparison of two dextranomer based bulking agents: Does bulking substance matter?

Endoscopic treatment of VUR has satisfying outcomes in properly selected cases. Younger age (<54 months) and previous history of failed injection history were found to be related to unfavorable results. Postoperative UTI occurs more frequently in patients with persisting reflux, preoperative breakthrough infection history and girls. The choice of one of the dextranomer-based substances does not affect the surgical outcome and postoperative UTI development.Table.
