Renal autotransplantation for localized amyloidosis of the ureter.

Localized amyloidosis of the ureter is a relatively rare disease, causing at times ureteral stenosis with hydronephrosis and renal function impairment to various extent. Although it is not malignant nearly all reported cases have been treated by nephroureterectomy because it is clinically difficult to differentiate this entity from ureteral malignancy. We report a case in which the ipsilateral kidney was salvaged successfully by renal autotransplantation. To the best of our knowledge, this is the first case reported of renal autotransplantation for localized amyloidosis of the ureter in the English literature. We suggest that renal autotransplantation be considered in cases of localized ureteral amyloidosis.
