Ureteroscopic management of upper tract transitional cell carcinoma

The expanding experience with endoscopic techniques for treating upper tract urothelial malignancy demonstrates its safety and efficacy in carefully selected patients. Diagnostic accuracy can be enhanced, and pathologic confirmation of tumor grade and stage is possible. In carefully selected patients who have low-grade and low-stage disease, the results of endourologic management have been encouraging. Patients with an anatomic or functionally solitary kidney, bilateral disease, or significant renal insufficiency can often be considered candidates for endoscopic treatment as the first line of therapy. In the setting of low-grade, low-stage disease in a patient with a normal contralateral kidney, the role of endourologic management remains controversial. Adjuvant topical therapy with mitomycin C or BCG seems to be safe and well tolerated after endoscopic management of upper tract TCC.
