신세포암과 신우요로 상피암의 CT상 감별점

Abstract

It may be difficult to differentiate renal cell carcinoma involving collecting system from renal pelvis urothelial tumor invading into renal parenchyma. The purpose of this study was to find out CT differential points of two diseases.

Renal cell carcinoma was characterized by no hydronephrosis(80%), normal CT renal function (100%) and outward bulging mass(100%). However, renal pelvis urothelial tumor showed hydronephrosis(70%), abnormal CT renal function(60%) and preserved reniform shape(100%). In conclusion, renal contour changes and CT renal function are reliable criteria in differentiating two diseases.
