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.
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.
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).
Our preliminary study suggests the face, content and construct validity of the adult ureteroscopy trainer as a high fidelity ureteroscopy and renoscopy trainer.
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。
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。
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）。
我们的初步研究表明，成人输尿管镜训练器作为一种高保真输尿管镜和肾镜训练器具有良好的表面、内容和结构有效性。
