[Pyelo-ureteric amyloidosis].

The authors report a case of urinary tract amyloidosis in a 55-year-old woman with no particular medical history. In the light of this original case, the authors present a review of the pathophysiology, diagnosis, histology and treatment of this disease. A review of the literature confirms the rarity of this entity and its variable clinical expression. An aetiological work-up must always be performed, as amyloidosis can be the complication of numerous diseases.
