Ultrasound is a useful tool for integrating clinical assessment with a bedside reliable imaging technique, but it requires adequate training. Ultrasonographic training involves examination performed on human models, in which many pathologic findings are not always readily available for the trainee to observe. The possibility of creating test objects that reproduce pathologic images allows the provision of training courses with those elements that are not always available. Our aims were to describe how to create a urinary bladder test object and to test its image quality and usefulness. Thus, we compared computed volume with the actual filling volume for five different devices to assess their reliability in volume estimation. Moreover, we evaluated the image quality and teaching utility using a 5-point Likert-type questionnaire among a group of learners. Computed bladder volume had excellent correlation with actual filling volume (p < 0.001, R2 = 0.9874). Trainees judged the ultrasound exploration realistic and considered the device useful in understanding ultrasound images and improving ultrasound skills. In conclusion, our device contributes to ultrasound training by providing a realistic ultrasound image, improving image understanding and skill development and allowing reliable bladder volume estimation.
