Robot-assisted laparoscopic nephroureterectomy.

Background: Laparoscopic nephroureterectomy for upper-tract urothelial tumors is a minimally invasive approach that parallels the open technique in oncologic efficacy. Multiple approaches to manage the distal ureter have been described. We developed a new technique using the daVinci robot system to perform a transvesical excision of the distal ureter and bladder cuff.

Methods: Ten consecutive patients with upper-tract urothelial cancer underwent a laparoscopic nephroureterectomy. The daVinci robot was docked through the umbilical, ipsilateral lateral rectus, and an additional contralateral lateral rectus port. The bladder was clam-shelled in a coronal orientation at the dome and the distal ureterectomy performed.

Results: Our technique was successful in all ten patients. The mean operative time for the entire case was 4.4 hours. The average hospital stay was 3 days.

Conclusions: Robot-assisted laparoscopic nephroureterectomy is a safe, minimally invasive approach to upper- tract urothelial cancer that reduces the technical challenge of excision of the distal ureter.
