Retrograde renal phlebography is important in the differential diagnosis when carcinoma of the renal pelvis is suspected. Vessel cut-offs, differences in contrast density, variations in vessel caliber, and irregular identations of the vessel wall can be seen with this technique. This seems to be the only method of demonstrating varicositites of the renal veins.
当怀疑有肾盂癌时，逆行肾静脉造影在鉴别诊断中很重要。通过这项技术可以看到血管截断、造影剂密度差异、血管管径变化以及血管壁的不规则压迹。这似乎是显示肾静脉静脉曲张的唯一方法。
