Prognostic variables in patients with transitional cell carcinoma of the renal pelvis and proximal ureter

Recent technological advances in urological endoscopic surgery of the renal pelvis and proximal ureter via ureteroscopy or percutaneous nephroscopy have made it possible to consider parenchymal-sparing procedures in patients with transitional cell carcinoma. To define the role of these procedures in the management of renal pelvic or proximal ureteral transitional cell carcinoma we analyzed retrospectively 31 patients who underwent nephroureterectomy for transitional cell carcinoma of the renal pelvis and/or proximal ureter. High grade upper urinary tract transitional cell carcinoma and a history of metachronous or synchronous bladder transitional cell carcinoma were independent adverse prognostic factors. However, patients with low grade upper urinary tract transitional cell carcinoma and no evidence of a urothelial field change had a 100 per cent 5-year survival rate. It would appear that parenchymal-sparing endoscopic techniques should be regarded with caution in patients with either high grade transitional cell carcinoma of the renal pelvis and proximal ureter or a history of bladder cancer.
