Abstract

PURPOSE

Surgical simulation technology may efficiently train and accurately assess the acquisition of many skills. Surgical simulators often lack realism and can be expensive at $3,000 to more than $60,000. We assessed the face, content and construct validity of a newly developed, anatomically accurate, reasonably priced high fidelity ureteroscopy and renoscopy trainer.

MATERIALS AND METHODS

A total of 46 participants, including attending urologists, urology residents, medical students and industry representatives, assessed the face and content validity of the simulator using a standard questionnaire. Ten experienced ureteroscopists with greater than 30 procedures per year and 10 novice ureteroscopists with 0 were assessed on the ability to perform flexible ureteroscopy, renoscopy and intrarenal basket extraction of a lower pole calculus using the adult ureteroscopy trainer (Ideal Anatomic Modeling, Holt, Michigan). Subject performance was assessed by an experienced ureteroscopist using a checklist, global rating scale and time to task completion.

RESULTS

Of participants 100% rated the trainer as realistic and easy to use, and thought it was a good training tool, 98% thought that it would serve as a good training format and 96% would recommend it to urology trainees. All participants recommended it for use in residency programs and 96% would or would have used it during residency. Only 37.5% vs 100% of experienced vs novice ureteroscopists would use it to practice. Of participants 9% foresaw a problem with the trainer. On the trainer experienced ureteroscopists scored significantly higher on the global rating scale (mean +/- SD 33.1 +/- 1.3 vs 15.0 +/- 2.7, p <0.0001) and checklist (4.1 +/- 1.0 vs 2.4 +/- 1.1, p = 0.004), and required less time to complete the task (141.2 +/- 40.1 vs 447.2 +/- 301.7 seconds, p = 0.01).

CONCLUSIONS

Our preliminary study suggests the face, content and construct validity of the adult ureteroscopy trainer as a high fidelity ureteroscopy and renoscopy trainer.

摘要

目的

手术模拟技术可以有效地训练和准确评估多项技能的掌握程度。然而，手术模拟器往往缺乏真实感，且价格昂贵，价格在 3000 美元至 60000 美元以上。我们评估了一种新开发的、解剖学上准确的、价格合理的高保真输尿管镜和肾镜训练器的表面、内容和结构有效性。

材料与方法

共有 46 名参与者，包括主治泌尿科医生、泌尿科住院医师、医学生和行业代表，使用标准问卷评估了模拟器的表面和内容有效性。10 名经验丰富的输尿管镜医师（每年进行 30 次以上手术）和 10 名新手输尿管镜医师（每年进行 0 次手术）使用成人输尿管镜训练器（理想解剖模型，密歇根州霍尔特）评估进行软性输尿管镜检查、肾镜检查和下极结石的肾内篮提取的能力。由经验丰富的输尿管镜医师使用检查表、总体评分和完成任务的时间来评估受试者的表现。

结果

100%的参与者认为该训练器具有真实感且易于使用，认为这是一种很好的培训工具，98%的人认为它将是一种很好的培训模式，96%的人会向泌尿科住院医师推荐它。所有参与者都建议将其用于住院医师培训计划，96%的人会在住院医师培训期间使用它，而只有 37.5%的经验丰富的输尿管镜医师会使用它进行练习，而 100%的新手会使用它进行练习。9%的参与者预计该训练器会存在问题。在训练器上，经验丰富的输尿管镜医师在总体评分（均值 +/- SD 33.1 +/- 1.3 对 15.0 +/- 2.7，p <0.0001）和检查表（4.1 +/- 1.0 对 2.4 +/- 1.1，p = 0.004）上的得分显著更高，且完成任务所需的时间更少（141.2 +/- 40.1 对 447.2 +/- 301.7 秒，p = 0.01）。
