Postoperative Ureteral Obstruction After Subureteral Injection of Dextranomer/Hyaluronic Acid Copolymer

Abstract

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.
