Robot-assisted laparoscopic nephroureterectomy offers a safe, minimally invasive option for upper-tract urothelial cancer. This technique simplifies the challenging distal ureter excision, improving patient outcomes.

Area of Science:

  • Urology
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Upper-tract urothelial tumors are often treated with nephroureterectomy.
  • Minimally invasive laparoscopic approaches offer oncologic efficacy comparable to open surgery.
  • Managing the distal ureter and bladder cuff presents a technical challenge in these procedures.

Purpose of the Study:

  • To introduce and evaluate a novel technique for transvesical excision of the distal ureter and bladder cuff using the daVinci robot system.
  • To assess the feasibility and safety of robot-assisted laparoscopic nephroureterectomy for upper-tract urothelial cancer.

Main Methods:

  • Ten patients with upper-tract urothelial cancer underwent laparoscopic nephroureterectomy.
  • The daVinci robot system was utilized with specific port placements (umbilical, ipsilateral, and contralateral lateral rectus).

Related Experiment Videos

  • A transvesical approach was employed, involving a coronal orientation clam-shell incision at the bladder dome for distal ureterectomy.

    • Main Results:

    • The described technique was successfully implemented in all ten patients.
    • The mean operative time for the complete procedure was 4.4 hours.
    • The average postoperative hospital stay was 3 days.

    Conclusions:

    • Robot-assisted laparoscopic nephroureterectomy is a safe and effective minimally invasive treatment for upper-tract urothelial cancer.
    • This robotic approach significantly reduces the technical difficulty associated with excising the distal ureter and bladder cuff.
