比较了球囊导管阻塞肾动脉逆行肾静脉造影(RBRVG)技术与其他放射学方法检测肾恶性肿瘤肾内静脉侵犯的诊断能力。31例疑为肾肿瘤或出血患者的RBRVG中,肾癌21例(肾细胞癌16例,肾盂癌5例),US和CT均未显示肾外或肾内静脉侵犯。先作下腔静脉以排除腔静脉或肾静脉血栓,然后把一根6.5F双腔球囊导管插进肾动脉,再将一根6.5F
The diagnostic ability of balloon catheter occlusion of renal artery reverse renal vein angiography (RBRVG) and other radiological methods for the detection of renal venous invasion of renal malignant tumors were compared. Among 31 RBRVG patients suspected of having renal tumor or hemorrhage, there were 21 cases of renal cell carcinoma (renal cell carcinoma in 16 cases and renal pelvis carcinoma in 5 cases), and neither US nor CT showed any extrarenal or intrarenal vein invasion. First for the inferior vena cava to exclude vena cava or renal vein thrombosis, and then a 6.5F dual-lumen balloon catheter inserted into the renal artery, and then a 6.5F
