“…In 2015, Salvad o et al created and validated an assessment tool that incorporated hand motion analysis for performance evaluation during semirigid ureteroscopy. 23 Using the previously validated ureteroscopy model by Matsumoto et al, 22 this group integrated a motion tracking device (the ICSAD [Imperial College Surgical Assessment Device]), that was placed on the dorsum of each hand to measure path length, number of movements, and overall length of time of the procedure.…”

Current Landscape of Surgical Assessment Models in Urology Residency Training

et al. 2023

Purpose:Assessing trainees’ surgical proficiency is an important aspect of urological surgical training. The current standard is the Urology Milestone Project, initially implemented in 2013. This evaluation is limited in that it contains only 3 questions on surgical competency per surgical modality with assessments occurring semi-annually without real-time operative feedback. However, since the Urology Milestones Project’s inception a plethora of competency-based surgical assessment tools have been described. We aim to perform a comprehensive review of the literature of these available tools and analyze their strengths and weaknesses as a way of providing a repository of available assessment strategies for further development of a more comprehensive and standardized assessment tool.Materials and Methods:A review of the primary literature was performed using key words such as “surgical assessment tools urology,” “surgical assessment tools prostate,” “bladder surgical assessment tools,” “renal surgical assessment tools urology,” and “surgical assessment tools urology task specific.” Technical and nontechnical skill assessments were included. One reviewer identified and analyzed studies that published assessment tools for use in surgical and urological training.Results:A total of 1,497 articles published between 1997-2022 were identified. Of these, 34 met the inclusion criteria. Eighteen (52.9%) were specialty nonspecific and 16 (47.1%) were specific for urological training. Of the 18 tools developed for general surgical principles, 12 (66.7%) had some form of validity, 9 (50.0%) were significantly reliable, and 2 (11.1%) were externally validated. Of the 16 tools developed specifically for use in urology training, 13 (81.3%) had some form of validity, 7 (43.8%) were significantly reliable, and none were externally validated. Of these 16 tools, 12 (75.0%) were procedure-specific and 4 (25.0%) were developed for general use in endourological procedures.Conclusions:Surgical training is evolving toward a competency-based model, as evidenced by the increase in assessment tools created within the past 10 years. These instruments not only provide objective feedback to trainees, but also monitor progression. However, they are heterogeneous in construct and utilization. There remains a need for the adoption of a standardized, valid, and reliable tool, ie, both procedure-specific and generalizable across multiple procedures for use in urology training.

“…Surgical simulations are already performed in operative urology and several simulator systems are already in use 10,15,22. However, these simulation systems typically lack anatomical details and are often fabricated from hard plastics with material properties that are very different from the target organ.…”

Soft 3D-Printed Phantom of the Human Kidney with Collecting System

et al. 2016

Organ models are used for planning and simulation of operations, developing new surgical instruments, and training purposes. There is a substantial demand for in vitro organ phantoms, especially in urological surgery. Animal models and existing simulator systems poorly mimic the detailed morphology and the physical properties of human organs. In this paper, we report a novel fabrication process to make a human kidney phantom with realistic anatomical structures and physical properties. The detailed anatomical structure was directly acquired from high resolution CT data sets of human cadaveric kidneys. The soft phantoms were constructed using a novel technique that combines 3D wax printing and polymer molding. Anatomical details and material properties of the phantoms were validated in detail by CT scan, ultrasound, and endoscopy. CT reconstruction, ultrasound examination, and endoscopy showed that the designed phantom mimics a real kidney’s detailed anatomy and correctly corresponds to the targeted human cadaver’s upper urinary tract. Soft materials with a tensile modulus of 0.8–1.5 MPa as well as biocompatible hydrogels were used to mimic human kidney tissues. We developed a method of constructing 3D organ models from medical imaging data using a 3D wax printing and molding process. This method is cost-effective means for obtaining a reproducible and robust model suitable for surgical simulation and training purposes.

“…En la actualidad, las oportunidades de aprendizaje para los residentes de urología se encuentran limitadas, dificultando la adquisición de habilidades quirúrgicas en los programas de residencia 10,11 . Esto se debe a múltiples causas, entre ellas están la necesidad de brindar una atención segura y de calidad al paciente, las restricciones en los horarios de trabajo de los residentes, los altos costos institucionales que implican la formación quirúrgica y el surgimiento de nuevas tecnologías 12,13 .…”

Validación De Un Modelo Simulado Inanimado Basado en Impresión 3d De Ureterorrenoscopía Flexible

2020

Objetivo: Establecer validez aparente, de contenido y constructo de un programa de simulación de ureterorrenoscopía flexible.Materiales y métodos: Se desarrolló un modelo de simulación de silicona para ureterorrenoscopía flexible, en el cual se establecieron 8 marcas de colores en los distintos cálices. Para la validación, se reclutaron urólogos expertos y residentes de urología con experiencia variable en este procedimiento. Se separaron en 3 grupos: G1 para residentes sin experiencia en ureteroscopía, G2 para residentes con experiencia variable y G3 para urólogos expertos. Se les solicitó realizar una navegación completa del modelo, en un tiempo máximo de 600 segundos. Al finalizar, cada participante contestó una encuesta respecto a la utilidad y realismo del modelo. Además, se midió tiempo total, número de puntos encontrados y cantidad de veces de reingreso a los cálices para validación de constructo.Resultados:15 personas participaron en la evaluación. Se obtuvo una mediana de 8,6 puntos para la utilidad del modelo y 6,75 puntos para el realismo de este. Los tiempos totales de navegación fueron 504, 293 y 133 segundos para G1, G2 y G3 respectivamente (p=0,02). De las 8 marcas, se encontraron en promedio 5,1, 6.6 y 7,3 (p=0,18), presentando un promedio de 9,5, 3,8 y 1,3 reintentos de exploración de los cálices en los respectivos grupos (p=0,11).Conclusiones: Se establece validez aparente y contenido para un modelo de ureterorrenoscopía flexible. El programa de simulación de ureterorrenoscopía flexible establecido, permite diferenciar novatos de expertos en cuanto a reducción en los tiempos de navegación.
