Ureteral and renal pelvic metastases from renal cell carcinoma.

Six patients with ureteral or renal pelvic metastases from renal cell carcinoma (RCC) were studied radiologically. Correlation with surgical and histologic findings confirmed renal venous involvement in 5 and lymphatic invasion in 3 patients. The possible role of nephroureterectomy or secondary ureterectomy in patients with RCC is discussed in the background of our cases, as are prior reports of this finding.
