Editorial Comment: Diagnostic ureteroscopy prior to nephroureterectomy for urothelial carcinoma is associated with a high risk of bladder recurrence despite technical precautions to avoid tumor spillage

摘要

The use of flexible ureterorenoscopy for the diagnosis (DFU) of suspected lesions in the renal pelvis, calyx and other segments of the collecting system is common in urology. This elegant work tries to use a systematization of the surgical access in order to evaluate the possibility of tumor spillage in other urinary segments, when handling is diagnostic or therapeutic in urothelial tumors.
