Results: The solution developed for medical training was considered a useful tool for training in urological anatomy, facilitating the translation of this knowledge to clinical practice. Surgeons reported their experience using this preoperative planning tool for surgery. The surgical planning solution was used during laparoscopic renal tumorectomy in an experimental model and video-assisted right upper lobectomy in an adult patient. Expert urological surgeons completed a questionnaire to evaluate its use. The urology training application provided access to a variety of anatomical and surgical training contents. Materials and Methods: Applications were developed for the use of the Microsoft HoloLens device. Herein, we present two solutions based on mixed reality that aim to improve both training and planning in minimally invasive surgery. However, access to this information often requires the support of an assistant and may compromise sterility in the surgical process. Conversely, advances in preoperative imaging have made it an essential part of any successful surgical procedure. Introduction: Medical training is a long and demanding process, in which the first stages are usually based on two-dimensional, static, and unrealistic content. 4Scientific Direction, Jesús Usón Minimally Invasive Surgery Centre, Cáceres, Spain.3Thoracic Surgery Unit, Cáceres University Hospital, Cáceres, Spain.2TREMIRS Project, Jesús Usón Minimally Invasive Surgery Centre, Cáceres, Spain.1Bioengineering and Health Technologies Unit, Jesús Usón Minimally Invasive Surgery Centre, Cáceres, Spain.Sánchez-Margallo 1* Carlos Plaza de Miguel 2 Roberto A.
