We report the case of a 68-year-old Japanese man who presented with postrenal azotemia due to bilateral upper ureteral stenosis. The patient's right kidney was nonfunctional; therefore, right nephroureterectomy was performed for the purpose of pathologic diagnosis. Histopathologic examination revealed follicular lymphoma with diffuse change in the ureter. With chemotherapy for malignant lymphoma, the stenosis of the left ureter was alleviated, and left renal function was preserved. Primary malignant lymphoma of the ureter is extremely rare. In cases of ureteral stenosis with ureteral wall thickening for which the cause is uncertain, the possibility of malignant lymphoma of the ureter should be considered.
我们报告了一例68岁的日本男性患者，其因双侧上输尿管狭窄出现肾后性氮质血症。患者的右肾无功能；因此，为进行病理诊断实施了右肾输尿管切除术。组织病理学检查显示输尿管存在滤泡性淋巴瘤伴弥漫性改变。通过对恶性淋巴瘤进行化疗，左输尿管狭窄得到缓解，左肾功能得以保留。原发性输尿管恶性淋巴瘤极为罕见。对于病因不明的输尿管壁增厚伴输尿管狭窄病例，应考虑输尿管恶性淋巴瘤的可能性。
