Dextranomer/hyaluronic acid injection is associated with a small risk of postoperative ureteral obstruction requiring endoscopic intervention, with an overall incidence of less than 0.7% of patients injected. Patients with voiding dysfunction or neurogenic bladder may be at increased risk. Intervention with temporary ureteral stenting is effective, technically simple and curative.
We report a large short-term single center experience with endoscopically injected Dx/HA. Although our cure rate of 64% was less than published rates for open surgery, the minimal morbidity and low complication rate of endoscopic treatment make it an attractive first line therapy for patients with VUR. Longer followup is required to better evaluate this technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
