Surgeons provided with 3D VR models were more likely to alter their surgical plan, with a "strong trend" toward increased use of nerve-sparing approaches to protect urinary continence and sexual function: 92% versus 78%. On multivariable analysis adjusting for other factors, having access to 3D VR models was a significant predictor of undetectable postoperative PSA.
"Notably, surgeons were often more aggressive with nerve sparing after viewing the 3D VR models," Dr. Shirk and colleagues write. This meant they were better able to "precisely select of the right operative pathway regarding margins," while avoiding nerve injury that could lead to problems with urinary and sexual functioning.

By overcoming the limitations of current imaging and surgical planning, the use of 3D VR models may help surgeons counsel patients more directly regarding projected trifecta outcomes – which may help patients to make treatment choices that reflect their preferences and appropriate expectations. Dr. Shirk and colleagues emphasize the need for further research on 3D VR models, including effects on longer-term outcomes of prostate cancer surgery.
About Urology Practice
An Official Journal of the American Urological Association (AUA), Urology Practice focuses on clinical trends, challenges and practice applications in the four areas of Business, Health Policy, the Specialty and Patient Care. Information that can be used in everyday practice will be provided to the urology community via peer-reviewed clinical practice articles (including best practices, reviews, clinical guidelines, select clinical trials, editorials and white papers), "research letters" (brief original studies with an important clinical message), the business of the practice of urology, urology health policy issues, urology education and training, as well as content for urology care team members.
About the American Urological Association
Founded in 1902 and headquartered near Baltimore, Maryland, the American Urological Association is a leading advocate for the specialty of urology, and has more than 23,000 members throughout the world. The AUA is a premier urologic association, providing invaluable support to the urologic community as it pursues its mission of fostering the highest standards of urologic care through education, research and the formulation of health care policy.
