Of all primary malignant renal tumors, 10% to 15% originate from the renal pelvis, and 90% to 92% of these tumors are transitional cell carcinomas. Nonetheless, renal pelvis transitional cell carcinoma extending into the inferior vena cava is very rare. We report one confirmed case and one highly suspicious case of renal pelvis transitional cell carcinoma with a tumor thrombus in the inferior vena cava. Both of our patients died within 6 months of initial diagnosis, indicating the poor prognosis and advanced stage of transitional cell carcinoma with an inferior vena cava thrombus. Transitional cell carcinoma should be considered in patients with obstruction of the renal vein and the inferior vena cava.
在所有原发性恶性肾肿瘤中，10%至15%起源于肾盂，其中90%至92%的肿瘤为移行细胞癌。然而，肾盂移行细胞癌延伸至下腔静脉的情况非常罕见。我们报告一例确诊病例和一例高度可疑病例，均为肾盂移行细胞癌伴下腔静脉肿瘤血栓形成。我们的两名患者均在初次诊断后6个月内死亡，这表明伴有下腔静脉血栓的移行细胞癌预后不良且分期较晚。对于肾静脉和下腔静脉梗阻的患者，应考虑移行细胞癌的可能。
