A training simulator for ultrasound-guided percutaneous nephrostomy insertion

Area of Science:

• Urology
• Medical Education
• Surgical Simulation

Background:

• Limited training opportunities exist for nephrostomy tube insertion due to increasing trainee numbers and evolving work patterns.
• Current commercial and biological phantoms are costly and not widely accessible, creating a need for affordable alternatives.
• Safe, effective training methods are crucial for developing proficiency in percutaneous nephrostomy.

Purpose of the Study:

• To develop and validate a low-cost, accessible gelatin-based phantom for nephrostomy tube insertion training.
• To provide a safe, non-threatening environment for medical trainees to practice percutaneous nephrostomy skills.
• To assess the face and content validity of the proposed gelatin phantom as a training tool.

Main Methods:

• A simple technique for creating a gelatin-based phantom was developed.
• The phantom was designed to simulate the anatomical and tactile properties relevant to nephrostomy procedures.
• Face and content validity were assessed to determine its suitability as a training simulator.

Main Results:

• A cost-effective and safe gelatin phantom for nephrostomy training was successfully produced.
• The phantom demonstrated face and content validity, indicating its relevance and applicability to clinical practice.
• The simulation allows trainees to familiarize themselves with techniques and equipment.

Conclusions:

• The gelatin-based phantom provides a valid and accessible training solution for nephrostomy tube insertion.
• This simulation tool can optimize clinical training by allowing skill development prior to supervised patient procedures.
• Utilizing this phantom can enhance trainee confidence and psychomotor skills for successful nephrostomy insertion.
