Computer-assisted surgery: virtual- and augmented-reality displays for navigation during urological interventions

Area of Science:

• Urology
• Surgical Navigation
• Medical Imaging

Background:

• Navigation technologies are advancing urological interventions.
• Diverse imaging modalities (CT, MRI, ultrasound) create surgical roadmaps.
• Registration techniques align virtual plans with surgical views.

Purpose of the Study:

• To review developments in virtual and augmented reality navigation for urological surgery.
• To provide an overview of current navigation procedures in urology.

Main Methods:

• Review of pre- and intra-operative imaging modalities.
• Analysis of registration methods (electromagnetic, mechanical, vision-based).
• Inclusion of new non-invasive intraoperative modalities (ultrasound, gamma probes, fluorescence cameras).

Main Results:

• Navigation systems utilize various imaging and registration techniques.
• New non-invasive modalities offer alternatives to X-ray exposure.
• Some studies suggest equal or better outcomes, but with small patient groups and limited follow-up.

Conclusions:

• Computer-assisted surgery concepts indicate a future for navigation in urology.
• Further validation with larger cohorts and long-term data is essential.
• Navigation holds potential to enhance guidance in urological interventions.
