Impact of High-fidelity Nonbiological Kidney Puncture Trainer on Residents' Skills During 30-Day Practical Course.

Objective: To describe the manufacture of the nonbiological kidney cavity puncture trainer under ultrasound control and its benefits during the 30-day learning course of junior residents.

Methods: Ten junior residents were included in this work. Each participant performed a kidney puncture on the described simulator under ultrasound control every day for a 30-day practical course. Also, ten urologists were included in the work and performed punctures on the trainer; the results obtained were compared with the residents' results on the 1st and 30th days of the study. The Face, content, construct, and criterion validities of the simulator have been defined. The residents also assessed the change in tactile sensations after the simulator's integrity restore and the increase in their motivation for a more in-depth study of all aspects of kidney puncture.

Results: All residents could independently perform a kidney puncture on the simulator through the calyx papilla, which was statistically significant compared with the results on day 1 of training. When comparing the final results of the residents with the urologists' ones, there were similar. Face, content, and construct validity were 4/5, 5/5, and 4.5/5. There was no change in tactile sensations during the everyday restoration of the simulator's integrity. All residents noted the positive effect of the described simulator on their motivation in mastering percutaneous kidney puncture.

Conclusion: The described simulator allows young residents to gain experience performing punctures of the kidney cavity, which positively affects their motivation to improve obtained skills further.
