Introduction & Objective :

Bedside suprapubic catheterization (SPC) is a fundamental skill required of all urology trainees. Ultrasound guidance during SPC insertion can minimize complications, and its use is recommended in clinical practice guidelines.  However, a lack of affordable simulation models and the unpredictability of bedside SPCs make learning this procedure difficult for trainees. We developed and initially validated a low-cost ultrasound-compatible SPC simulator that allows trainees to safely and deliberately practice the task while acquiring skills that are transferable to bedside SPCs.


Methods :

The SPC simulator consists of 7 components (Table 1). 7 staff urologists and 4 interventional radiologists conducted a SPC using the model with ultrasound guidance (Figures 1 and 2). To assess for face and content validity, each participant rated the model using a 5-point Likert scale on 3 domains: anatomic realism, usefulness as a training tool, and overall reaction.


Results : Participants were in practice for an average of 10 years (range 2-23), and the median number of SPCs performed was 50. For the domains, anatomic realism scored a mean of 4.1 (mean of 4.0 for sonographic realism). Usefulness as a training tool scored a mean of 4.3, and the mean for overall reaction was 4.4. Participants strongly agreed that the model should be incorporated into urology residency (mean=4.4), the skills are transferable to patients (mean=4.3), and its use would improve trainee confidence (mean=4.6). The cost of the model is approximately $48 CAD, and can be used multiple times during one session.


Conclusions : This novel, low-cost, easily reproducible ultrasound-compatible SPC training simulator received positive evaluations from urologists and interventional radiologists as a useful model for teaching bedside ultrasound-guided SPC insertion. This model will be integrated into our annual urology boot camp curriculum for first-year residents, which will allow for the evaluation of trainees as they learn SPC on the model with instruction and feedback. Additional research is required for construct validation.
