Urology Residents Simulation Training Improves Clinical Outcomes in Laparoscopic Partial Nephrectomy

Area of Science:

• Urology
• Surgical Education
• Medical Simulation

Background:

• Partial nephrectomy (PN) is the standard treatment for small renal masses.
• Laparoscopic partial nephrectomy (LPN) requires significant surgical skill.
• Modern surgical training emphasizes off-site skill development.

Purpose of the Study:

• To evaluate the impact of resident laparoscopic surgical skills training on LPN outcomes.
• To assess the effectiveness of simulation-based training in a public teaching hospital.

Main Methods:

• Retrospective analysis of LPN cases performed by urology residents.
• Stratification of patients into two periods: pre-simulation training (Era 1) and post-simulation training (Era 2).
• Comparison of surgical outcomes including estimated blood loss, ischemia time, length of stay (LOS), and Trifecta achievement.

Main Results:

• Residents with simulation training (Era 2) showed significantly reduced estimated blood loss, ischemia time, and LOS compared to Era 1.
• The Trifecta achievement rate was significantly higher in Era 2 (77.5%) versus Era 1 (p=0.007).
• Patient baseline characteristics were similar between the two eras.

Conclusions:

• Simulation-based surgical training demonstrably improves clinical outcomes in laparoscopic partial nephrectomy.
• Adequate resident training is crucial for successful LPN implementation and patient safety.
• This study underscores the value of structured simulation programs in surgical residency.
