Abstract

BACKGROUND

Virtual reality (VR) has been recognized as a useful modality in the training of surgical skills. With respect to basic endoscopic skill training of urology, we sought to investigate the effectiveness of the UroMentor(TM) virtual reality simulator (VRS) in the skill acquisition of flexible cystoscopy.

METHODS

Urologists familiar with rigid cystoscopy procedures were selected to take part in a virtual training course of flexible cystoscopy. Changes in total operating time, frequency of injury, number of digital markers inside the bladder, and the global rating scale (GRS) scores were assessed following eight repeated training sessions on the UroMentor(TM).

RESULTS

Eighteen urologists voluntarily took part in the study. Total operating time was significantly lower after eight sessions of training by comparison ((111 ± 10) seconds and (511 ± 67) seconds, respectively; P < 0.001). Additionally, the frequency of injury decreased with training from (12 ± 2) times to (5 ± 1) times (P < 0.001), while the number of digital markers observed increased from 9 ± 0 to 10 ± 1 (P = 0.005). Finally, training with the UroMentor(TM) resulted in a GRS increase from (1.3 ± 0.2) points to (3.9 ± 0.2) points (P < 0.001).

CONCLUSION

the VRS UroMentor(TM) can improve urologists' ability to perform flexible cystoscopy and could be used as an effective training tool for trainees.

摘要

背景

虚拟现实（VR）已被认为是一种用于外科技能培训的有用模式。在泌尿外科基本内镜技能培训方面，我们试图研究 UroMentor（TM）虚拟现实模拟器（VRS）在软性膀胱镜检查技能获得中的有效性。

方法

选择熟悉硬性膀胱镜检查程序的泌尿科医生参加软性膀胱镜检查的虚拟培训课程。在 UroMentor（TM）上进行八次重复训练后，评估总操作时间、损伤频率、膀胱内数字标记数量和总体评估量表（GRS）评分的变化。

结果

18 名泌尿科医生自愿参加了这项研究。与培训前相比，经过八次培训后，总操作时间明显降低（分别为（111±10）秒和（511±67）秒，P<0.001）。此外，随着训练的进行，损伤频率从（12±2）次减少到（5±1）次（P<0.001），而观察到的数字标记数量从 9±0 增加到 10±1（P=0.005）。最后，使用 UroMentor（TM）进行培训可使 GRS 从（1.3±0.2）分增加到（3.9±0.2）分（P<0.001）。
