Abstract: 70歳男性.患者は約3年前に右上部尿管狭窄による右膿腎症で右腎摘除術を受け,1年後に肉眼的血尿で受診したが異常を認めず,血尿も自然消失した.しかし今回,再度の肉眼的血尿にて受診となった.超音波検査では右遺残尿管の拡張を認め,CTでは遺残尿管は全長にわたり肥厚し,尿管内部に造影効果を伴う充実性腫瘍を認めた.逆行性尿管造影では不整な尿管壁が描出され,採取した尿細胞診はclass IVで,右遺残尿管腫瘍と診断し,腹部傍腹直筋切開で尿管口を含めて右遺残尿管摘除術を施行した.病理所見では,肉眼的には尿管内腔にに乳頭状に増生する腫瘍を認め,顕微鏡的には乳頭状腫瘍は筋層に浸潤していたが尿管内に留まり,移行上皮癌G2,pT2と診断された.術後3年経過現在,局所再発や遠隔転移は認めていない
A case of primary carcinoma of the remaining ureter is reported. A 70-year-old man presented with asymptomatic gross hematuria. Three years ago, he had received right nephrectomy for pyonephrosis. Although drip infusion pyelography (DIP) and cystoscopy showed no abnormal findings, computed tomography (CT) and retrograde ureterography demonstrated the irregular thickening of the right remaining ureteral wall. He underwent right ureterectomy with bladder cuff resection. Pathological examination revealed transitional cell carcinoma of the remaining ureter. He has been free of disease for 3 years.
