Flexible cystoscopy and pigtail catheter extraction are two of the first procedures that residents learn to perform in the outpatient urological clinic. Systematic training of these procedures is known to be helpful for performing a safe and fast pigtail catheter removal in a real-life setting. However, due to high costs and scarce availability of training models, many residents present a limited learning curve, which could have a direct negative impact on the patients´ well-being and outcome.
We present the necessary material and methods to construct a bladder model designed for the training of early years’ residents for the simulation of pigtail catheter removal. We propose the low priced construction of a Do-It-Yourself-(DIY)-model with building supplies store products and excessive outdated material of the everyday clinical use presenting an alternative way of learning the procedure in a safe and repeatable manner.
The approximate construction time is 150 minutes; the cost of the simulator is less than 30 euros. The model can be used directly after construction. We built a bladder-like simulator representing the natural intravesical anatomy with tubes as artificial ureters. Through the tubes pigtails can be placed in the bladder antegradely. The pigtail catheters can be extracted with the help of a flexible cystoscope (e.g. excessive single use flexible cystoscope). We can repeat the pigtail removal as many times as wanted. Thanks to its compact design the model can be easily stored and due to the solid structure, there is no need of filling it with liquid to expand the interior wall of the bladder model.
There is a shortage of low-cost bladder models to learn pigtail catheter removal, one of the main and characteristic procedures in the outpatient urological clinic. The widespread use of affordable simulators could contribute to a better level of education of early years´ urological trainees. We proposed the construction of a low-cost, easily storable and reusable simulator to train the pigtail catheter removal procedure.
