Bladder diverticulum is rarely associated to hydroureteronephrosis. We present clinical images of an adult patient with a bladder diverticulum near the ureterovesical junction (UVJ) with secondary obstruction. An 84-year-old man presented with left hydroureteronephrosis and a presumed 25-mm left ureteral stone at UVJ on computed tomography. Cystoscopy revealed a stone located in a bladder diverticulum just cephalad and medial to left ureteral orifice; the patient successfully underwent endoscopic laser cystolithotripsy with resolution of his hydronephrosis. Juxta-UVJ bladder diverticula may cause obstruction of the ipsilateral upper urinary tract.
膀胱憩室很少与输尿管积水肾积水相关。我们呈现了一位成人患者的临床图像，该患者在输尿管膀胱连接部（UVJ）附近有膀胱憩室，伴有继发性梗阻。一位 84 岁男性因左侧输尿管积水和 CT 显示的 UVJ 处疑似 25mm 左侧输尿管结石就诊。膀胱镜检查显示结石位于左侧输尿管口上方和内侧的膀胱憩室内；患者成功接受了内镜激光膀胱碎石术，肾积水得到缓解。UVJ 附近的膀胱憩室可能导致同侧上尿路梗阻。
