局限性输尿管淀粉样变性1例报告

A case of localized ureteral amyloidosis

局限性输尿管淀粉样变性是一种罕见疾病,临床和影像学表现与输尿管癌相似。本文报道1例中年男性患者,表现为无痛性肉眼血尿。CT与MRI尿路造影检查提示肿瘤征象,行输尿管活检,病理诊断为淀粉样变性。行腹腔镜下输尿管部分切除术联合膀胱瓣代输尿管术。术后肾功能正常。术后随访1年无局部复发和远处转移。

Localized ureteral amyloidosis is a rare disease clinically and radiographically similar to ureteral carcinoma.We reported a 56-year-old man with painless gross hematuria.CT and Magnetic resonance urography(MRU)examinations showed tumor signs and ureteral amyloidosis was diagnosed by ureteral biopsy.Laparoscopic partial ureterectomy combined with boari flap was performed and the patient's renal function was preserved.There was no local recurrence and distant metastasis during the 1-year follow-up.
