Abstract
Subureteral endoscopic injection is a safe and effective treatment for vesicoureteral reflux (VUR). Dextranomer/hyaluronic acid (Dx/HA) is the most commonly used bulking agent for the treatment of VUR. We report a confusing radiographic finding of calcified Dx/HA injection initially simulates distal ureteral stone in a female patient who has intermittent lumbar pain. Calcification of Dx/HA implants may mimic distal ureteral calculi; therefore, urologists should be aware of the potentially confusing radiographic images.
Highlights
The prevalence of vesicoureteral reflux (VUR) in children has been estimated at 0.4%–1.8%

Summary
The prevalence of vesicoureteral reflux (VUR) in children has been estimated at 0.4%–1.8%. A 29-year-old female patient presented with complaint of intermittent right flank pain. A lack of hydronephrosis and flank pain may help to distinguish calcified implants from ureteral calculi in those with VUR treatment. This may be difficult in patients who present with subjective pain and mild hydronephrosis. We planned to perform ureterorenoscopy for this patient who was referred to us from the external center because the patient had intermittent pain and mild hydronephrosis Follow-up after 3 months CT showed no change in calcification at the ureterovesical junction
