14. Distal ureter and bladder cuff excision using the “Keyhole Technique” during Robotic Radical Nephroureterectomy
ABSTRACT Introduction: Upper tract urothelial carcinoma (UTUC) accounts for 5-10% of all urothelial tumors (1). Radical nephroureterectomy (RNU) remains the standard treatment for high, and low-grade UTUC (2). Although the open approach has been considered the gold standard, robotic techniques have shown comparable oncological outcomes with potential advant
