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.

Although primary amyloidosis of the ureter is rare, it should be included in the differential diagnosis of ureteric strictures.
