Abstract

Background: There are few realistic and accessible laparoscopic pyeloplasty training models. The aim of this study is to develop a functional training model through user-centered design that depicts the pathological features of pelvicoureteric junction obstruction (PUJO).

Methods: Realistic patient-matched anatomical models of the kidney, renal pelvis, and ureter were created based on segmentations of computed tomography (CT) scans of a paediatric patient with PUJO who underwent laparoscopic pyeloplasty. Three training model versions (polyjet, resin, and silicone) were produced, tested, and published. Training model testing was conducted by consultant surgeons (n = 14), training surgeons (n = 5), and medical students (n = 8). Face validity testing was conducted to assess realism and usefulness of training models on a 10-point Likert-type scale. Training model accessibility was assessed using equipment availability and cost to set-up and produce as proxy measures.

Results: Participants significantly preferred polyjet and silicone models over resin models for overall rating (6.9 ± 2.3, 7.9 ± 1.1, and 5.0 ± 1.8) respectively; and usefulness in trainees (7.6 ± 2.1, 8.6 ± 0.9, and 5.0 ± 3.1) respectively. While both the polyjet and silicone models were found to be realistic and useful, the silicone model is considered more accessible due to the ready availability of the manufacturing equipment and materials and around 300-fold reduction in cost compared to polyjet.

Conclusions: A surgeon-assessed realistic and useful pyeloplasty surgical training model was developed here which enables surgical practice on challenging small anatomical features. The comparatively low cost and accessibility of the silicone model can enable trainees to practice the procedure depicting the realistic pathological features in environments with limited resources.

肾盂成形术手术训练模式的开发与面效性检验。
背景:目前很少有现实可行的腹腔镜肾盂成形术训练模式。本研究的目的是通过以用户为中心的设计,建立一个描述盆腔输尿管交界处梗阻(PUJO)病理特征的功能训练模型。方法:基于一名接受腹腔镜肾盂成形术的PUJO患儿的计算机断层扫描(CT)分割,建立切合实际的肾脏、肾盂和输尿管解剖模型。三个训练模型版本(聚喷气机,树脂和硅胶)生产,测试和出版。培训模式检验由会诊外科医生(n = 14)、培训外科医生(n = 5)和医学生(n = 8)进行。采用10分likert量表进行人脸效度测试,评估训练模型的真实感和有效性。使用设备可用性和设置和生产成本作为代理措施来评估培训模型的可及性。结果:与树脂模型相比,参与者在总体评分上明显更喜欢聚喷射和硅树脂模型(分别为6.9±2.3、7.9±1.1和5.0±1.8);受训者的有用性分别为7.6±2.1、8.6±0.9和5.0±3.1。虽然聚合物喷射模型和硅胶模型都被认为是现实和有用的,但由于制造设备和材料的现成可用性,硅胶模型被认为更容易获得,并且与聚合物喷射模型相比成本降低了约300倍。结论:本文开发了一种外科医生评估的现实和有用的肾盂成形术手术培训模型,该模型使具有挑战性的小解剖特征的手术实践成为可能。硅胶模型的相对低成本和可及性使受训者能够在资源有限的环境中练习描绘真实病理特征的程序。
