A case of bilateral ureteral fibrosis is reported. The patient, a 32-year-old man, was admitted as a result of acute renal failure. Ultrasonography showed bilateral hydronephrosis, so that in-dwelling percutaneous nephrostomy tubes were immediately inserted in the bilateral kidneys. Since retrograde and antegrade pyelograms revealed bilateral midureteral stricture, idiopathic retroperitoneal fibrosis at first suspected, but no mass in the retroperitoneal space was found by a computed tomogram. An exploratory laparotomy showed no fibrous mass in the retroperitoneal space either, but that the wall of the ureter was thickened. Biopsy of the ureter led to a histological diagnosis of fibrosis. Since evidence of inflammation such as elevation of the erythrocyte sedimentation rate and cross-reacting protein was found, 50 mg of prednisolone has been administered every other day, with the result that inflammation is now under control. This report deals with specific ureteral fibrosis related to idiopathic systemic fibrosis and collagen disease.
报告一例双侧输尿管纤维化病例。患者为一名32岁男性，因急性肾衰竭入院。超声检查显示双侧肾积水，遂立即在双侧肾脏置入经皮肾造瘘管。逆行和顺行肾盂造影显示双侧输尿管中段狭窄，最初怀疑为特发性腹膜后纤维化，但计算机断层扫描未发现腹膜后间隙有肿块。剖腹探查也未发现腹膜后间隙有纤维性肿块，但输尿管壁增厚。输尿管活检得出纤维化的组织学诊断。由于发现有炎症迹象，如红细胞沉降率和交叉反应蛋白升高，每隔一天给予50毫克泼尼松龙，目前炎症已得到控制。本报告探讨了与特发性系统性纤维化和胶原病相关的特定输尿管纤维化。
