This study shows a kidney displacement simulator accurately visualizes renal anatomy before surgery. This virtual surgical planning tool helps surgeons identify critical vessels, reducing operative risks for malignant renal tumors.

Area of Science:

  • Urology
  • Surgical Technology
  • Medical Imaging

Background:

  • Malignant localized renal or ureteral neoplasms require precise surgical intervention.
  • Accurate visualization of hilar anatomy and vascular structures is crucial for successful nephrectomy.
  • Minimizing operative risks and complications is a primary goal in oncologic surgery.

Purpose of the Study:

  • To evaluate the efficacy of a novel kidney displacement simulator in pre-operative surgical planning for renal neoplasms.
  • To assess the accuracy of virtual laparoscopic images generated from multi-slice computed tomography (MSCT) data.
  • To compare the simulator's visualization of vascular structures with intraoperative findings.

Main Methods:

  • Twelve patients with malignant renal or ureteral neoplasms underwent MSCT.

Related Experiment Videos

  • Volume rendering and virtual laparoscopic images were created using a dedicated workstation.
  • A retroperitoneal balloon was used to displace the kidney ventrally.
  • Simulator images were compared with intraoperative video during retroperitoneal laparoscopic nephrectomy.

    • Main Results:

    • The kidney displacement simulator demonstrated 100% sensitivity for renal arteries and 93% sensitivity for renal veins.
    • Hilar anatomy, tumors, and major vessel relationships were accurately depicted.
    • Visualization of adrenal and gonadal veins corresponded precisely with intraoperative views.
    • The system successfully predicted desired portions of major and branched vessels.

    Conclusions:

    • The kidney displacement simulator is a valuable tool for pre-operative planning in surgeries for renal neoplasms.
    • It accurately visualizes critical vascular structures, including small branched vessels.
    • This technology can guide surgeons, reduce operative risks, and potentially decrease complications.
