Localized primary amyloidosis of the ureter.
A 57-year-old man with a history of right-sided renal colic had a stricture of the right ureter which was suspected to be caused by a tumour or retroperitoneal periureteric fibrosis. Peroperative frozen section examination revealed tumour-forming amyloidosis of the ureter. The right kidney therefore could be salvaged by an end-to-end ureter anastomosis. Although primary amyloidosis of the ureter is rare, it should be included in the differential diagnosis of ureteric strictures.
