Primary localized amyloidosis of the ureter and bladder managed by ileal interposition.

Amyloidosis of the ureter is a rare condition. It is even rarer when it involves both the ureter and bladder. The case presented is the second known case of combined amyloidosis of the bladder and ureter and the first combined case to be treated successfully by ileal ureter replacement. Historically, amyloidosis of the ureter has been treated by nephroureterectomy. Based on the benign nature of the disease, amyloidosis of the ureter is optimally treated with a kidney-sparing procedure such as ileal ureter replacement.
