A 72-year-old man was admitted to another hospital because of general fatigue and dyspnea secondary to renal insufficiency. Abdominal computed tomography (CT) and magnetic resonance imaging showed left atrophic kidney, right hydronephrosis, and an intra-pelvic mass of soft-tissue density located anterior to the sacrum, involving the right ureter at the level between the 5th lumber vertebra and the sacrum. He was referred to our hospital after percutaneous nephrostomy was constructed into right kidney. CT-guided needle biopsy revealed the idiopathic retroperitoneal fibrosis, leading us to give him steroid therapy. Three weeks later, radiographic findings showed a remarkable reduction of the mass and the improvement of the right ureteral stricture.
一名72岁男性因肾功能不全继发全身乏力和呼吸困难入住另一家医院。腹部计算机断层扫描（CT）和磁共振成像显示左肾萎缩、右肾积水，以及位于骶骨前方盆腔内的软组织密度肿块，累及第5腰椎和骶骨之间水平的右侧输尿管。在对右肾进行经皮肾造瘘术后，他被转诊至我院。CT引导下穿刺活检显示为特发性腹膜后纤维化，遂对其进行类固醇治疗。三周后，影像学检查结果显示肿块明显缩小，右侧输尿管狭窄有所改善。
