Abstract：
UNASSIGNED: The aims were to describe a software-based reconstruction of the patient-specific kidney cavity intraluminal appearance via a head-mounted device and to estimate its feasibility for training novices.
UNASSIGNED: In total, 15 novices were recruited. Each novice was shown a three-dimensional reconstruction of a patient\'s computed tomography scan, whose kidney was printed. They then joined the surgeon in the operating room and assisted them in detecting the stone during flexible ureteroscopy on the printed model. Then, each participant did a 7-day virtual reality (VR) study followed by virtual navigation of the printed kidney model and came to the operating room to help the surgeon with ureteroscope navigation. The length of the procedure and the number of attempts to find the targeted calyx were compared.
UNASSIGNED: With VR training, the length of the procedure (p = 0.0001) and the number of small calyces that were incorrectly identified as containing stones were significantly reduced (p = 0.0001). All the novices become highly motivated to improve their endourological skills further. Participants noticed minimal values for nausea and for disorientation. However, oculomotor-related side effects were defined as significant. Five specialists noticed a good similarity between the VR kidney cavity representation and the real picture, strengthening the potential for the novice\'s education via VR training.
UNASSIGNED: Virtual reality simulation allowed for improved spatial orientation within the kidney cavity by the novices and could be a valuable option for future endourological training and curricula.

摘要：
■目的是通过头戴式设备描述基于软件的患者特定肾腔腔内外观重建，并评估其培训新手的可行性。
■总共，招募了15名新手。向每个新手展示了患者计算机断层扫描的三维重建，印有谁的肾.然后，他们加入了手术室的外科医生，并在打印模型上的输尿管软镜检查期间协助他们检测结石。然后，每位参与者进行了为期7天的虚拟现实(VR)研究,然后对打印的肾脏模型进行虚拟导航,并来到手术室帮助外科医生进行输尿管镜导航.比较了程序的长度和试图找到目标花萼的次数。
■通过VR训练，手术时间(p=0.0001)和被错误识别为含有结石的小肾盏的数量显著减少(p=0.0001).所有的新手都变得非常积极，以进一步提高他们的泌尿技能。参与者注意到恶心和迷失方向的最小值。然而,动眼相关副作用定义为显著。五位专家注意到VR肾腔表示与真实图片之间的相似性，通过VR培训加强新手教育的潜力。
■虚拟现实模拟允许新手改善肾腔内的空间定向，并且可能是未来的泌尿训练和课程的有价值的选择。
