Ureteral Obstruction Due to Primary Localized Amyloidosis

Abstract

Localized amyloidosis of the ureter is a rare condition. There are only 27 cases reported. Because of the difficulty in differentiating between localized amyloidosis or other benign conditions and a malignant tumor many cases have led to nephrou-reterectomy. We report a case of a middle aged woman who had an almost complete obstruction of the right ureter caused by amyloidosis. Biopsies were taken via a ureteroscope prior to exploration of the ureter enabling the patient to be treated with local excision and ureteroneocystostomy instead of nephroureterectomy.

Key words:

• primary
• localized amyloidosis
• ureter
• obstruction
• ureteroscopy
• ureteroneocystostomy.
