Background and purpose: Laparoscopic nephrectomy (LN) has largely replaced open nephrectomy. The aim of this study was to describe a validated modular system for training urologists in LN in the context of the shorter training times available in the current era.
Methods: After attendance at dry and wet laboratory courses, three mentees (trainee, new consultant, and an experienced open surgeon) were mentored through a five-module LN training system in our center followed by the mentee's own hospital. A minimum of 25 independent procedures were then performed by mentees in their own hospital.
Results: There were 17 to 32 mentored cases needed to become competent in LN, followed by up to 5 observed cases in the mentee's own center. Subsequently, data from the first 105 cases (80 LN and 25 laparoscopic nephroureterectomies [LNU]) performed by the three surgeons after the end of their training without observation by their mentor were retrospectively collected and analyzed. There were three conversions (2.9%). For LN and LNU, respectively: median operative time was 140 minutes (65-390 min) and 180 minutes (90-300 min); median estimated blood loss was 30 mL (0-2000 mL) and 50 mL (0-2000 mL); median postoperative stay was 4 days (2-45 days) and 6 days (3-27 days). Four (3.8%) patients needed a postoperative transfusion. There was no 30-day mortality.
Conclusion: Mentees matched the median British Association for Urological Surgeons (BAUS) registry operative time (LN, 120-180 min, LNU, 180-240 min) and had lower conversion rates (2.9% vs 6.4% for BAUS). Mentees matched median BAUS database reported blood loss (LN and LNU <500 mL) and length of stay (LN-4 days, LNU-5 days). This modular training program allows urologists to become independent in LN after a short period of focused training in the training center followed by a short period of mentoring in the mentee's own center.
