Virtual reality and intracorporeal navigation in urology.

Objective: To provide an overview of the meaning and types of virtual reality (VR) system, its current applications in the field of urology and future implications.

Synthesis Of The Evidence: The concept of VR involves the generation of computer environments with which a user can interact directly. Urology technologies and surgical practices are constantly evolving and RV simulation has become an important complement in urologist training curricula, taking into account not only simulations in surgical techniques, but also in non-surgical techniques such as communication and decision making. VR approaches for image-guided surgery have demonstrated potential in the field of urology by supporting guidance for various disorders. An increasing number of pre and intraoperative imaging modalities have been used to create detailed surgical route maps. The tracing of these surgical roadmaps with the surgical vision of real life has been produced in different ways (electromagnetic, acoustic, optical ...), recommending the combination of several approaches to provide a superior result. One of the disadvantages of navigation systems is soft tissue deformations, requiring confirmatory images. Although early studies report that navigation surgeries provide results equal to or greater than conventional approaches, most of the work has been done in relatively small groups of patients, thus requiring studies with larger sample sizes.

Conclusions: The development of VR offers urologists many opportunities, with surgical simulation being one of its most important applications today. Likewise, the first clinical studies have demonstrated the potential of augmented reality (2D and 3D models) to improve surgical accuracy, describing different navigation systems for different urological surgical interventions.
