3D-printed procedural task trainer for the aspiration of penile corpus cavernosa in ischaemic priapism

Abstract

Objective: The development and initial clinical assessment of a novel 3D-printed procedural task trainer for the aspiration of penile corpus cavernosa in ischaemic priapism. Methods: A task trainer for the aspiration of penile corpus cavernosa was designed and manufactured using commercially available 3D printing equipment. The trainer was assessed in two separate training sessions led by faculty investigators. Participants in the sessions were asked to complete a post-procedure survey with regards to the utility and realism of the task trainer. Results: The participants (n = 14) covered a broad spectrum of clinician types. The trainer was perceived by the participants as being anatomically realistic, and especially while under drapes provided a reasonable facsimile of real clinical setup. The trainer proved resilient to multiple attempts at aspiration by multiple participants. Conclusions: Participant and facilitator feedback indicates that the task trainer is a useful platform to train for what is a low frequency, but high stakes, procedure. Small numbers of participants preclude statistical rigour and certainty regarding overall performance of the trainer. However, the uniformity in the responses would suggest that this is indeed a task trainer that is ‘fit for purpose’.
