Low-Cost Training Simulator for Open Dismembered Pyeloplasty: Development and Face Validation.

Area of Science:

• Medical Education
• Surgical Simulation
• Pediatric Surgery

Background:

• Traditional surgical apprenticeship models are evolving.
• Open surgery for ureteropelvic junction (UPJ) presents unique pediatric training challenges due to small workspaces and fine sutures.
• Enhanced dexterity is crucial for successful UPJ procedures.

Purpose of the Study:

• To develop and validate a low-cost training simulator for open dismembered pyeloplasty.
• To address the need for improved surgical training tools in pediatric urology.
• To assess the face validity and usability of the novel simulator.

Main Methods:

• The simulator was constructed using readily available materials: Kraft envelopes, syringes, balloons, and tape.
• A 5-point Likert-type scale evaluation form was used to assess the simulator.
• The simulator was distributed to 31 French pediatric surgery departments for evaluation by surgeons of varying expertise levels.

Main Results:

• 180 devices were sent, with 118 procedures performed by experts, fellows, and residents.
• Statistically significant differences in perceived difficulty and anatomical representation were noted across expertise levels.
• The simulator achieved a global score of 4.2/5 for realism, face validity, and usability.

Conclusions:

• The developed low-cost simulator is an efficient tool for teaching and training open dismembered pyeloplasty.
• The simulator demonstrates significant potential as a valuable educational resource in pediatric surgical training.
• Further validation may confirm its role in improving surgical dexterity for UPJ procedures.
