Critical robotic equipment malfunction during robotic-assisted laparoscopic prostatectomy (RALP) is rare, affecting only 0.4% of cases in high-volume centers. This study reviews robotic system reliability in prostate cancer treatment.

Area of Science:

  • Urology
  • Surgical Technology
  • Robotics in Medicine

Background:

  • Robotic-assisted laparoscopic prostatectomy (RALP) is increasingly utilized for prostate cancer treatment.
  • The reliability of the da Vinci robotic system, a key technology in RALP, requires further investigation.
  • Equipment malfunction during RALP can necessitate procedure conversion or abortion.

Purpose of the Study:

  • To conduct the first large-scale, multi-institutional review of robotic equipment malfunctions during RALP.
  • To evaluate the perioperative robotic malfunction rate in high-volume RALP procedures.
  • To identify common robotic system components prone to failure.

Main Methods:

  • A questionnaire was distributed to high-volume, experienced surgeons performing RALP.

  • Surgeons reported data on total RALPs performed, equipment malfunctions, and procedure outcomes (conversions/abortions).
  • Data analysis focused on identifying the frequency and nature of robotic system failures.

    • Main Results:

    • Eleven institutions contributed data, totaling 8240 RALP cases with a median surgeon volume of 700 cases.
    • Critical robotic equipment malfunction occurred in 34 cases (0.4%).
    • Most malfunctions involved robotic arms and the optical system; 24 cases were cancelled, and 10 were converted to alternative procedures.

    Conclusions:

    • Critical robotic equipment malfunction is exceptionally rare in centers with high RALP volumes.
    • The nonrecoverable malfunction rate for the da Vinci system in this study was 0.4%.
    • High-volume centers demonstrate robust reliability of robotic systems in prostatectomy.
