VesEcho Training System: Suprapubic Catheterization under Ultrasound Guidance

Area of Science:

• Urology
• Medical Simulation
• Surgical Education

Background:

• Suprapubic catheterization is a key skill for urology trainees.
• Ultrasound guidance is recommended to minimize complications during this procedure.
• A novel, cost-effective, and sonographically accurate training model was developed.

Purpose of the Study:

• To develop and evaluate a novel simulation model for ultrasound-guided suprapubic catheterization.
• To assess the model's realism and utility in resident training.
• To determine the impact of the training on resident comfort and proficiency.

Main Methods:

• A simulation model was constructed using a water balloon (bladder), pelvic bone replica, rectus fascia, and a gelatin mold.
• The model was integrated into a resident training course for suprapubic catheterization.
• Pre- and post-training surveys assessed anatomical/sonographic realism and procedural comfort among 13 urology residents.

Main Results:

• The simulator achieved high scores for anatomical (4.2/5) and sonographic realism (4.4/5).
• Residents rated the simulator's value as a training tool highly (4.7/5) and the course overall (5/5).
• Overall comfort with the procedure significantly increased post-training (mean increase of 5.1 points, p < 0.001).

Conclusions:

• The novel simulation model and curriculum were positively received by urology residents.
• The training enhanced resident confidence in performing ultrasound-guided suprapubic catheterization.
• This sustainable model is readily adaptable for urology training programs.
