title: [Protocol for percutaneous treatment of upper urinary tract urothelial tumors].
abstract: We develop the diagnostic methodology to select patients with upper urinary tract urothelial tumors who are candidates for percutaneous endoscopic treatment. This treatment is indicated for low grade and stage lesions in the pyelocalyceal system (> 3 cm), lumbar ureter (> 1-2 cm) and for failures of the retrograde approach. In this protocol, we emphasize the performance of intraoperative biopsy and pyelocalyceal mapping, as well as the need of a second look to rule out residual tumor.
