To overcome these limitations, we developed the “lift-and-cut method,” a minimally invasive surgery (MIS) designed to minimize gastric resection without opening the gastric lumen.

This widespread usage and the reported benefits of 3D imaging in urology should reassure the audience about the effectiveness of this technology. VR/AR/MR were primarily used for simulation (19%) and navigation (16%). While 63% expressed interest in these technologies, 51% reported never having used them. Among the barriers to adoption, 25% cited high cost, 24% cited the effort required for data processing, and 14% cited the difficulty of use.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>3D images and VR/AR/MR technologies were expected to play a pivotal role in urological robotic surgery.
