Abstract

Introduction: This study aimed to evaluate fresh-frozen cadavers (FFC) as a novel model for percutaneous nephrolithotomy (PCNL) training, focusing on ultrasound-guided supine PCNL.

Methods: Sixteen urologists participated in a 2-day course at a tertiary center to assess the utility of an FFC model for ultrasound-guided supine PCNL. After the procedure, the participants completed a 24-question evaluation of the FFC model using a 5-point Likert scale. The questionnaire assessed tissue quality, US imaging, procedural steps, overall experience compared to live patient procedures, and suitability of the model for both basic and advanced supine PCNL training.

Results: The tactile sensation, skin stiffness, and distensibility of the calyces resembled real-life scenarios as the cadavers thawed. Similarly, US quality was worse in frozen cadavers and improved after irrigation with the collection system. Valdivia-Galdakao positioning is considered more difficult than in real life, because of rigor mortis.

Conclusion: FFC demonstrated robust content validity as a training model for PCNL. The model provides a realistic and effective training experience, offering a promising tool for developing critical surgical skills, while minimizing radiation exposure and procedural risks.

新鲜冷冻尸体作为经皮肾镜取石术（PCNL）新的训练模型。

本研究旨在评估新鲜冷冻尸体（FFC）作为经皮肾镜取石术（PCNL）训练的新模型，重点是超声引导的仰卧PCNL。方法：16名泌尿科医生在某三级中心参加了为期2天的课程，以评估FFC模型在超声引导仰卧PCNL中的应用。在此过程之后，参与者使用5点李克特量表完成了对FFC模型的24个问题的评估。问卷评估了组织质量、超声成像、程序步骤、与现场患者手术相比的总体经验，以及模型对基础和高级仰卧PCNL训练的适用性。结果：尸体解冻后的触感、皮肤硬度和肾盏的膨胀性与真实情况相似。同样，美国冷冻尸体的质量较差，在用收集系统灌溉后有所改善。由于尸体僵硬，Valdivia-Galdakao的定位被认为比现实生活中更困难。结论：FFC作为PCNL的训练模型具有显著的内容效度。该模型提供了一个现实和有效的培训经验，为开发关键的外科技能提供了一个有前途的工具，同时最大限度地减少辐射暴露和手术风险。

期刊介绍： Research and Reports in Urology is an international, peer-reviewed, open access, online journal. Publishing original research, reports, editorials, reviews and commentaries on all aspects of adult and pediatric urology in the clinic and laboratory including the following topics: Pathology, pathophysiology of urological disease Investigation and treatment of urological disease Pharmacology of drugs used for the treatment of urological disease Although the main focus of the journal is to publish research and clinical results in humans; preclinical, animal and in vitro studies will be published where they will shed light on disease processes and potential new therapies. Issues of patient safety and quality of care will also be considered.
