CTが診断に有用であつた尿管腫瘍の1例

A CASE OF URETERAL TUMOR DIAGNOSED BY COMPUTED TOMOGRAPHY

緒言

　原発性尿管腫瘍は近年報告例が増加してはいるが，比較的まれな疾患である。診断は通常臨床症状，膀胱鏡検査，尿細胞診，尿路X線検査などによりなされている。しかし，症例によつては診断の困難なこともある。われわれは最近，尿管腫瘍を疑つてCTを施行し，診断し得た1例を経験したので報告する。

A 66-year-old woman, visited Tottori University Hospital with the chief complaint of asymptomatic macrohematuria on Oct. 4, 1979. RP showed right hydroureteronephrosis due to right lower ureteral stenosis. Computed tomography (CT) was employed to investigate the right lower ureter, which showed a tumor in the right lower ureter, confined within the ureteral wall. Diagnosis of the right ureteral tumor with right hydroureteronephrosis was made and under general anesthesia right complete nephroureterectomy was performed on Oct. 26, 1979.

So, the accuracy of the preoperative diagnosis was confirmed by the operation.
