Abstract
Objectives

To develop a suprapubic catheter (SPC) training model as no specific realistic training model exists to replicate SPC exchange where a catheter tract is present.

Materials and methods

We describe a novel, anatomically realistic, animal simulator model for use in SPC training, which was trialed at a national urology simulation boot camp by new urology trainees and validated by expert urologists. A scale reproduction of an abdominal wall was created using a porcine abdominal wall. A segment of small bowel was stitched around a size 16F Foley catheter to form a tract. Abdominal wall tissue was excised cylindrically to create an opening, and the small bowel tract was passed through the abdominal wall and sutured anteriorly, producing a realistic SPC tract: inferiorly, the tract was anastomosed to a porcine urinary bladder. This model was evaluated by 10 expert urologists for content validity with an 8-item 5-point rating scale used to evaluate domains relevant to the simulator.

Results

The domains were scored between 1 and 5 by 10 expert urologists, 1 being «strongly disagree» and 5 being «strongly agree». The average expert ratings of the domains were then calculated and tabulated following the training course. There was an average global rating of 4.2/5 for the model, with an average usefulness for training score of 4.6/5.

Conclusion

The feedback from experts and trainees (informal) was overwhelmingly positive. On average, our experts reported high satisfaction with their experience using this simulator as a training tool.

Resumen
Objetivos

Desarrollar un modelo de formación sobre el catéter suprapúbico (CSP), ya que no existe un modelo realista específico para replicar el recambio de CSP.

Materiales y métodos

Describimos un modelo animal de simulación, anatómicamente realista, para su uso en la formación del manejo del CSP, el cual fue probado por residentes de urología y validado por urólogos expertos. Usando una pared abdominal porcina, se creó una reproducción a escala de la pared abdominal. Un segmento del intestino delgado fue cosido alrededor de un catéter de Foley de tamaño 16F para formar el tubo. Se crea una apertura cilíndrica en la pared abdominal, realizando un canal para introducir el tracto del intestino delgado; este fue suturado en la parte anterior, produciendo una sonda de CSP de apariencia realista. En la parte inferior la sonda fue anastomosada a una vejiga urinaria porcina. La validez de contenido del modelo fue evaluada por 10 urólogos expertos, con una escala de calificación de 8 ítems y 5 puntos, utilizada para evaluar las distintas áreas relevantes del simulador.

Resultados

Estas áreas fueron puntuadas de 1 a 5 por 10 urólogos expertos, siendo 1 «totalmente en desacuerdo» y 5 «totalmente de acuerdo». El promedio de la calificación de los expertos fue calculado y tabulado al finalizar la formación. La calificación global del modelo fue de 4,2/5, con un promedio de utilidad para la formación de 4,6/5.

Conclusión

La respuesta (informal) obtenida por parte de expertos y alumnos fue altamente positiva. En promedio, nuestros expertos reportaron una experiencia satisfactoria con el uso de este simulador como herramienta de formación.
