Tumor thrombus from renal cell carcinoma (RCC) usually occurs within the renal vein. We present the first report of a tumor thrombus from RCC extending from the kidney down the ureter and into the lumen of the bladder. This case both: (1) provides evidence for growth of RCC along the urinary tract, and (2) poses a staging dilemma.
肾细胞癌（RCC）的肿瘤血栓通常发生在肾静脉内。我们首次报告了一例RCC肿瘤血栓从肾脏向下延伸至输尿管并进入膀胱腔的病例。该病例兼具：（1）为RCC沿泌尿道生长提供了证据，以及（2）带来了分期难题。
