Development of a low-cost model for laparoscopic pyeloplasty simulation

ABSTRACT

Aims: Simulation is increasingly important in the training of paediatric urology;training time lost due to the Covid-19 pandemic, patient safety concerns and the uptake of technology (i.e., robotics) means that trainees must develop new methods of attaining operative competency. Laparoscopic pyeloplasty can be technically challenging and involves a steep learning curve to be confident in performing this procedure independently. We therefore aimed to develop a low-cost, high-fidelity model which trainees could create using easily available materials. Method(s) Unique Party Balloon (Unique Party Store)-1200 Scarlet Red (pack of 10) [2.34] were filled with cotton wool pads (2 packs of 50 rounds 1-Aldi) and fashioned into a kidney shape. Pink 102 latex Balloons (PABBEU) [4.99] were filled with a 50 ml of water to create the renal pelvis and superglued (Loctite pack of 3, Ryman) [4.99] to the kidney. Then Long Pastel Twisting Balloons (pack of 50)-[4.29] were attached over the tied end of the renal pelvis creating the ureter. The model was then secured into the Laparoscopic box trainer using Velcro Hook and Loop Coins (Syntego, 105 pack) [2.95]. Result(s) The model was utilised in departmental skills sessions. Feedback demonstrated the model provided a realistic feel performing the anastomosis due to the latex, water-filled, balloons. Total cost per model was 1.10 (20 models). Conclusion(s) We demonstrate a low-cost model of laparoscopic pyeloplasty which trainees can create easily themselves. However, further work will be needed to improve the model for anatomical relations, particularly crossing vessels.
