title: Management of Vesicoureteral Reflux by Endoscopic Injection of Dextranomer/Hyaluronic Acid in Adults.
abstract: A 74-year-old man presented for evaluation after discovery of a left bladder-wall tumor. He underwent transurethral resection of bladder tumor (TURBT) operation for treatment of low-grade, Ta urothelial cancer of the bladder. The patient developed recurrent disease and returned to the operating room for repeat TURBT, circumcision, and administration of intravesical mitomycin C. The patient developed balanitis xerotica obliterans 4 years post-circumcision, requiring self-dilation with a catheter. He subsequently developed 3 consecutive episodes of left-sided pyelonephritis. Further investigation with voiding cystourethrogram (VCUG) revealed Grade 3, left-sided vesicoureteral reflux (VUR). Due to existing comorbidities, the patient elected treatment with endoscopic dextranomer/hyaluronic acid injection. A post-operative VCUG demonstrated complete resolution of left-sided VUR. This patient has remained symptom free for 8 months post-injection, with no episodes of pyelonephritis.
