AUA 2018: 3-Dimensional, Virtual Reality Planning for Robotic Partial Nephrectomy
His study compared 30 retrospective and 30 prospective patients who underwent robotic partial nephrectomy. The surgeons of the retrospective control patients, from previous medical records, used 2-dimensional CT and MRI scans to plan for the operative procedure. However, the prospective intervention patients’ CT and MRI scans were converted to 3-dimensional virtual reality models for the surgical planning. The converted 3-dimensional virtual reality models were then loaded onto the surgeon’s mobile phone application to use before and during the surgery. He collected demographic and clinical data from both patient groups. The outcome measures included: (OR) time, clamp time, estimated blood loss (EBL), and hospital stay.
His results displayed that using the 3-dimensional virtual reality model had decreased overall operative time (p<0.0001), clamp time, estimated blood loss, and were more likely to stay in the hospital for less than two days. Thus, he concluded that the 3-dimensional virtual reality model played an important role for improving operative planning, impacting outcomes, and providing a benefit for the patient, physician, and hospital. He added that further work should replicate the findings by increasing the randomized controlled trials, integrating test methods into the surgical workflow, and investigating the use and result of other complex case types.
