Can preoperative planning using IRIS™ three-dimensional anatomical virtual models predict operative findings during...

Area of Science:

• Urology
• Surgical Technology
• Medical Imaging

Background:

• Robot-assisted partial nephrectomy (RAPN) is a complex procedure requiring precise surgical planning.
• Advanced visualization tools are crucial for improving surgical outcomes and spatial understanding.
• The IRIS™ system offers a 3D planning model for RAPN.

Purpose of the Study:

• To evaluate the predictive validity of the IRIS™ planning tool for RAPN.
• To assess the degree of overlap between preoperative surgical plans and intraoperative execution using IRIS™.
• To determine the clinical utility and effectiveness of IRIS™ in RAPN.

Main Methods:

• A prospective study involving 31 patients undergoing RAPN by four experienced urologists.
• Urologists reviewed the IRIS™ 3D model and completed preoperative questionnaires on surgical plans.
• Postoperative questionnaires assessed IRIS™ utility, efficiency, and effectiveness; overlap between planned and actual procedures was analyzed.

Main Results:

• Surgeons reported confidence in 67.7% of cases preoperatively.
• IRIS™ aided spatial sensation in 96.8% of intraoperative cases.
• High overlap was observed between planned and executed surgical approaches (90.0% for ischemia technique).

Conclusions:

• IRIS™ demonstrates high predictive accuracy for RAPN planning.
• The tool facilitates a strong correlation between preoperative planning and intraoperative execution.
• This study is the first to validate IRIS™ predictive accuracy in RAPN through direct comparison.
