Area of Science:

  • Urology
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Robot-assisted laparoscopic radical prostatectomy is increasingly common.
  • The transperitoneal approach is the predominant method used worldwide.
  • Alternative surgical approaches are being explored to optimize outcomes.

Purpose of the Study:

  • To report the experience and outcomes of robot-assisted extraperitoneal laparoscopic radical prostatectomy.
  • To evaluate the feasibility and safety of this novel surgical technique.
  • To compare results with existing literature on prostatectomy.

Main Methods:

  • A total of 325 patients with clinically localized prostate cancer underwent the procedure over two years.
  • Perioperative, oncological, and functional data were prospectively collected.

  • The extraperitoneal approach was utilized with da Vinci robotic assistance.
  • Main Results:

    • The average operative time was 130 minutes with a mean blood loss of 196 cc.
    • No intraoperative conversions to open surgery were required.
    • Pathological stages ranged from pT2a to pT3b, with a 13% positive surgical margin rate and 2.1% positive nodal disease.

    Conclusions:

    • The extraperitoneal approach enhances robotic dexterity and visualization while avoiding peritoneal cavity complications.
    • This technique simulates open retropubic prostatectomy, offering potential advantages.
    • The extraperitoneal approach is likely to increase in popularity as surgical experience grows.
