A case of localized ureteral amyloidosis / 中华泌尿外科杂志

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.
