A virtual reality simulator provides a novel training model for improving surgical skills in a variety of fields. They can simulate a variety of surgical scenarios to improve the overall skills required for endoscopic operations, and also record the operative process of trainees in real-time and allow for objective evaluation. At present, some simulators for transurethral resection of the prostate (TURP) are available. The utility of virtual reality simulators in training of transurethral prostatectomy was investigated.
Thirty-eight urologists were randomly selected to take part in a simulation based training of TURP using the TURPSim(TM) system. Pre and post-training global rate scale (GRS) scores and objective parameters recorded by the simulator were assessed. Then, questionnaires were filled out.
Compared with baseline levels, the GRS scores of trainees increased (18.0 ± 4.0 vs. 12.4 ± 4.2, P < 0.001), while the rate of capsule resection (26.3% ± 0.6% vs. 21.2% ± 0.4%, P < 0.001), amount of blood loss ((125.8 ± 86.3) ml vs. (83.7 ± 41.6) ml, P < 0.001), external sphincter injury (3.6 ± 2.9 vs. 2.0 ± 2.0, P < 0.001) decreased significantly after training. Most trainees were satisfied with the simulator based training and believed that the simulator accurately mimicked actual surgical procedures and could help improve their surgical skills.
As a new method of training on transurethral prostatectomy skills, training of TURP using a virtual simulator can help urologists improve their surgical skills and safety. Therefore, the application of the TURPSim(TM) system in education and training of urologic surgery is warranted.
虚拟现实模拟器为提高各种领域的手术技能提供了一种新颖的培训模式。它们可以模拟各种手术场景，提高内镜手术所需的整体技能，还可以实时记录学员的手术过程，并进行客观评估。目前，有一些经尿道前列腺切除术（TURP）模拟器。本研究旨在探讨虚拟现实模拟器在经尿道前列腺切除术培训中的应用。
随机选择 38 名泌尿科医生使用 TURPSim（TM）系统进行 TURP 模拟基础培训。评估培训前后全球评分量表（GRS）评分和模拟器记录的客观参数，然后填写调查问卷。
与基线水平相比，学员的 GRS 评分升高（18.0 ± 4.0 比 12.4 ± 4.2，P < 0.001），包膜切除率（26.3% ± 0.6% 比 21.2% ± 0.4%，P < 0.001）、出血量（（125.8 ± 86.3）ml 比（83.7 ± 41.6）ml，P < 0.001）和外括约肌损伤（3.6 ± 2.9 比 2.0 ± 2.0，P < 0.001）显著降低。大多数学员对基于模拟器的培训感到满意，并认为模拟器准确模拟了实际手术过程，有助于提高他们的手术技能。
作为一种经尿道前列腺切除术技能培训的新方法，使用虚拟模拟器进行 TURP 培训可以帮助泌尿科医生提高手术技能和安全性。因此，TURPSim（TM）系统在泌尿科手术的教育和培训中的应用是合理的。
