title: Obstruction of a ureter by isolated primary focal amyloidosis.
abstract: A rare case of obstruction of the pelvic segment of the ureter by an isolated focus of primary amyloidosis is described. The operation consisted of resection of the constricted segment of the ureter and end-to-end anastomosis, with very good early and late results. The differential diagnosis and therapy of this type of ureteral obstruction are discussed.
