Abstract:
Localized amyloidosis of the ureter is a rare condition. Because of the difficulty in differentiating between localized amyloidosis and an obstruction due to other benign or malignant conditions of the urinary tract, in some cases even an unnecessary nephroureterectomy is performed. We describe a patient with obstructive amyloidosis of the right ureter. Diagnosis was confirmed by endoscopy with biopsies. The patient was treated successfully by partial ureterectomy and ureteroneocystostomy. No systemic involvement of other organs was detected and after a 2-year follow-up no local recurrence developed.
