Transitional cell carcinoma of ureteral stump after radical nephrectomy for renal cell carcinoma.

A 68-year-old male presented with microscopic hematuria during a routine checkup after undergoing a radical nephrectomy for renal cell carcinoma. Retrograde ureterography demonstrated a ureteral stump tumor. The ureteral stump was completely resected with a bladder cuff and histologic diagnosis was grade 2 to 3 transitional cell carcinoma of the ureteral stump. He is doing well and has been tumor-free for 2 years. The ureteral stump must be correctly evaluated using retrograde ureterography in any patient with a prior history of bladder cancer. Even if a patient had no history of ureterial cancer, whenever hematuria is present in the follow-up period after nephrectomy for renal cell carcinoma, a retrograde pyelogram should be performed.
