ureteral neoplasms/amyloid

BACKGROUND Morphologic findings of amyloid in urine cytology material have rarely been reported because amyloidosis of the urinary tract is a relatively uncommon disorder. We present a case of primary amyloidosis of the ureter, including catheterized urine cytologicfindings. METHODS A 78-year-old

A case of localized amyloidosis of the ureter is reported. The patient was a 49-year-old female whose chief complaint was macrohematuria. Roentogenographic examination showed left hydronephrosis due to stenosis of left middle ureter. Left nephrouretectomy with cuff was performed with a diagnosis of

A 78-year-old woman was referred to our hospital with chief complaint of colicky right flank pain. Computed tomography (CT) demonstrated right hydronephrosis and a wall thickening in the right ureteropelvic junction. Right nephroureterectomy was performed under a clinical diagnosis of invasive

A 46-year-old female was referred to our hospital with a complaint of left flank pain. Ultrasongraphy and computed tomography demonstrated a left hydronephroureter due to stenosis with a ureteral mass in the left lower ureter. Retrograde pyelography revealed severe stricture of left lower ureter and

OBJECTIVE To analyze a new case of primary localized amyloidosis of the ureter, describing the differential diagnosis with ureteral tumors and its pathogenic mechanism. METHODS Description of the case of a male patient who presented clinical symptoms of renoureteral pain and hematuria and an image
