Robot-assisted, Laparoscopic and Transvaginal Surgery for Pelvic Organ Prolapse: a Comparative Retrospective Single-Center Study.

International urogynecology journal·2026

This study introduces an augmented reality (AR) system to visualize blood vessels during robotic sacrocolpopexy, improving surgical safety by guiding mesh placement and avoiding critical vascular structures.

Area of Science:

  • Medical technology
  • Surgical navigation
  • Augmented reality in medicine

Background:

  • Pelvic organ prolapse requires surgical correction via sacrocolpopexy.
  • Precise mesh anchoring to the sacral promontory is crucial but risky due to hidden vessels.
  • Existing methods lack intraoperative imaging for real-time guidance.

Purpose of the Study:

  • To introduce an augmented reality (AR) navigation system for visualizing vessels at the sacral promontory during robotic sacrocolpopexy.
  • To integrate AR visualization into the Da Vinci robotic console, eliminating the need for intraoperative imaging.

Main Methods:

  • Identified anatomical landmarks (round ligament insertions) from preoperative CT scans and intraoperative endoscopic views.
  • Used stereo endoscopic triangulation to determine 3D landmark positions.

  • Developed a registration algorithm using a dedicated rod and iterative minimization to align CT-based vascular models with the endoscopic view.

    • Main Results:

    • Achieved geometric alignment of CT-based vascular models with intraoperative views with an average error of 10 mm in a phantom study.
    • Demonstrated accuracy within the clinically safe vascular window at the sacral promontory.
    • The system provided consistent overlay for mesh placement, with the rod acting as a stable reference.

    Conclusions:

    • The developed AR system enables visualization of vascular anatomy during robotic sacrocolpopexy, offering anatomical guidance.
    • This marks the first application of AR-based navigation in gynecological surgery.
    • The study confirms technical feasibility, with future work focusing on clinical validation.
