Comparison of Single-docking Robotic-assisted and Traditional Laparoscopy for Retroperitoneal Lymph Node Dissection During Nephroureterectomy With Bladder Cuff Excision for Upper-tract Urothelial Carcinoma.

Objective: To compare the results of traditional laparoscopy and a simple, single-docking robotic approach for retroperitoneal lymph node dissection (RPLND), nephroureterectomy, and bladder cuff excision.

Materials And Methods: We evaluated 63 and 37 consecutive patients who underwent laparoscopic and robotic nephrouretectomy with RPLND, respectively, for upper-tract urothelial carcinoma (UTUC).

Results: Our robotic approach was associated with improved lymph node procurement (21.
