title: Endourologic treatment of renal pelvic and ureteral transitional cell carcinoma.
abstract: Endoscopic treatment of patients with upper urinary tract transitional cell carcinoma is recommended in those with tumor in a solitary kidney, bilateral disease, renal dysfunction, and significant intercurrent illness that precludes a major abdominal surgical procedure. Endoscopic management also may be appropriate in selected patients with small, low-grade lesions in the presence of a normal contralateral kidney. Almost all ureteral tumors and some renal collecting system lesions can be managed using rigid and/or flexible ureteroscopy, which is associated with less bleeding and more rapid recovery than a percutaneous approach. However, larger renal malignancies can be managed effectively using percutaneous resection. Six patients with upper tract transitional cell carcinoma underwent endoscopic resection. The antegrade and retrograde surgical techniques are described. With follow-up up to 23 months, local recurrence in two patients was managed successfully by repeat endoscopic resection. No patient has experienced disease progression or developed metastases.
