Modelo de entrenamiento para el manejo precoz del priapismo / A training model to teach early management of priapism

Antecedentes: El priapismo isquémico es una emergencia urológica que requiere atención médica temprana para evitar daños irreversibles en la función eréctil. La aspiración cavernosa es el primer paso en el tratamiento. Actualmente no hay modelos de entrenamiento satisfactorios para desarrollar habilidades en un ambiente controlado. Por lo tanto, hemos desarrollado un novedoso modelo de entrenamiento para enseñar a los alumnos los pasos de la aspiración del pene de una manera segura y representativa.Materiales y métodosHemos desarrollado un modelo de priapismo usando un antiguo simulador para el entrenamiento del cateterismo. La validez del modelo fue evaluada por participantes y urólogos experimentados en un Boot Camp de urología. Todos habían tratado al menos cinco casos reales de priapismo. Las respuestas fueron reportadas usando una Escala Likert de cinco puntos. Los datos se analizaron utilizando IBM SPSS Statistics V25. La correlación intraclase se calculó mediante un «Modelo aleatorio unidireccional».ResultadosOnce urólogos y siete aprendices participaron en la evaluación. La apariencia del modelo fue la característica mejor evaluada del modelo de priapismo. La retroalimentación táctil de la inserción de la aguja para la aspiración también se consideró realista, con un 72,6% informándolo como «bueno» o «muy bueno» y un 85,7% opinó que el modelo era realista para la inserción de la aguja. La correlación intraclase entre los expertos fue de 0,552. La mayoría de los aprendices (83,3%) informó una simulación realista. Todos los evaluadores estuvieron de acuerdo o muy de acuerdo en que el modelo proporcionaba una buena experiencia de simulación que sería útil para la enseñanza. (AU)

Background: Ischaemic priapism is a urological emergency with early treatment required to prevent irreversible loss of erectile function. Corporal aspiration is the first step in management. Currently, there are no satisfactory training models to develop skills in a controlled environment. We have therefore developed a novel training model to teach trainees the steps of penile aspiration in a safe and representative way.Materials and methodsWe have developed a priapism model using an old catheterisation teaching model. Face validity of the model was assessed by participants and experienced urologists teaching on a urology boot camp. All had managed at least 5 cases of actual priapism. Responses were reported using a 5-point Likert Scale. Data were analysed using IBM SPSS Statistics V25. The intra-class correlation was calculated using a «One-way Random model».ResultsEleven urologists and seven trainees participated in the evaluation. The model appearance was reported as the best simulation trait of the priapism model. Tactile feedback from needle insertion for aspiration was also felt to be realistic with 72.6% reporting it as «Good» or «very good» and 85.7% reported the model to be realistic for needle insertion. Intra-class correlation amongst experts was 0.552. Majority of trainees (83.3%) reported a realistic simulation. All evaluators agreed or strongly agreed that the model provided a good simulated experience that would be useful in training. (AU)

BACKGROUND: Ischaemic priapism is a urological emergency with early treatment required to prevent irreversible loss of erectile function. Corporal aspiration is the first step in management. Currently, there are no satisfactory training models to develop skills in a controlled environment. We have therefore developed a novel training model to teach trainees the steps of penile aspiration in a safe and representative way. MATERIALS AND METHODS: We have developed a priapism model using an old catheterisation teaching model. Face validity of the model was assessed by participants and experienced urologists teaching on a urology boot camp. All had managed at least 5 cases of actual priapism. Responses were reported using a 5-point Likert Scale. Data were analysed using IBM SPSS Statistics V25. The intra-class correlation was calculated using a «One-way Random model¼. RESULTS: Eleven urologists and seven trainees participated in the evaluation. The model appearance was reported as the best simulation trait of the priapism model. Tactile feedback from needle insertion for aspiration was also felt to be realistic with 72.6% reporting it as «Good¼ or «very good¼ and 85.7% reported the model to be realistic for needle insertion. Intra-class correlation amongst experts was 0.552. Majority of trainees (83.3%) reported a realistic simulation. All evaluators agreed or strongly agreed that the model provided a good simulated experience that would be useful in training. CONCLUSION: Our model provides a realistic simulation of corporal aspiration. It can be used repeatedly. Overall, the proposed model appears to be a promising tool for training junior doctors in the initial management of ischaemic priapism.
