目的：评估面部有效性，构建有效性和虚拟现实TURP模拟器的培训优势。方法：11个新手（无TURP经验）和7位专家（> 200个TURP）完成了一项虚拟现实的中间裂口前列腺切除任务（Turpsim（ TM）（俄亥俄州克利夫兰的Simbionix USA Corp.）。绩效指标（切除（PR）的百分比（PR），囊囊切除百分比（CR）和时间核心环路活跃而无需组织接触（TAWC）（TM），并在新手和专家之间进行了比较以评估构造有效性。口头评论。口头评论。由任务完成后的专家提供的专家来评估面部有效性。 （TM）。分辨率：专家每分钟的前列腺明显更高（p <0.01），并且没有组织接触的活动时间明显较少（p <0.01），而新手则能够进行模拟。有效地，在重复训练后，新手指出了所有测量参数的显着改善，这证明与专家组显着不同（p = 0.18）。结论：这项研究已经建立了TURPSIM（TM）的面部和构造有效性。也已经证明了使用此工具训练新手的潜在好处。 （c）2012年外科助理有限公司由Elsevier Ltd.发布的所有权利保留。
Objective: To assess face validity, construct validity and the training benefits of a virtual reality TURP simulator.Method: 11 novices (no TURP experience) and 7 experts (>200 TURP's) completed a virtual reality median lobe prostate resection task on the TURPsim (TM) (Simbionix USA Corp., Cleveland, OH). Performance indicators (percentage of prostate resected (PR), percentage of capsular resection (CR) and time diathermy loop active without tissue contact (TAWC) were recorded via the TURPsim (TM) and compared between novices and experts to assess construct validity. Verbal comments provided by experts following task completion were used to assess face validity. Repeated attempts of the task by the novices were analysed to assess the training benefits of the TURPsim (TM).Results: Experts resected a significantly greater percentage of prostate per minute (p < 0.01) and had significantly less active diathermy time without tissue contact (p < 0.01) than novices. After practice, novices were able to perform the simulation more effectively, with significant improvement in all measured parameters. Improvement in performance was noted in novices following repetitive training, as evidenced by improved TAWC scores that were not significantly different from the expert group (p = 0.18).Conclusions: This study has established face and construct validity for the TURPsim (TM). The potential benefit in using this tool to train novices has also been demonstrated. (c) 2012 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.
