Renal pelvic recurrence of renal cell carcinoma.

An 85-year-old man was referred for gross hematuria and a recurrent renal pelvic mass in a solitary left kidney, status post right nephrectomy for renal cell carcinoma 11 years previously. Three years before referral he had undergone ureteroscopic fulguration of a renal pelvis mass that had proved to be metastatic renal cell carcinoma on biopsy. We performed percutaneous resection of the renal pelvic mass, with no local recurrence at 1-year follow up. Contralateral renal pelvic recurrence is a rare form of renal cell carcinoma metastasis.
