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.
输尿管下内镜注射是治疗膀胱输尿管反流（VUR）的一种安全有效的方法。葡聚糖omer/透明质酸（Dx/HA）是治疗VUR最常用的填充剂。我们报告了一例令人困惑的影像学表现，在一名间歇性腰痛的女性患者中，钙化的Dx/HA注射最初模拟了远端输尿管结石。Dx/HA植入物的钙化可能会模仿远端输尿管结石；因此，泌尿外科医生应注意可能令人困惑的影像学图像。
