BERKELEY, CA (UroToday.com) - This video demonstrates the biopsy technique of a papillary upper tract urothelial carcinoma lesion by using the stainless steel flat-wire basket. The tumor is trapped between the wires, which are subsequently closed snugly but not completely. The specimen is removed en bloc thus avulsing a piece of tumor. The ureteroscope, basket, and specimen are removed as a single unit to avoid loss of tissue in the working channel. This technique enables debulking of a large lesion as well as obtaining a big piece of tumor for pathologic diagnosis.
