Abstract
OBJECTIVE: To describe and illustrate the evolution of surgical technique, emphasizing technical modifications of laparoscopic donor nephrectomy (LDN) and the impact on complication outcome. METHODS: This is a retrospective observational study of prospectively collected data on all consecutive purely LDN surgeries performed at a tertiary academic medical center (n = 1325), performed between March 2000 and October 2013. RESULTS: Over time, LDN was performed on older patients, changing from a mean of 35.7 years in 2000 to 41.2 years in 2013 (P <.001). Additionally, mean blood loss decreased from 75 mL in 2000 to 21.6 mL in 2013 (P <.001). However, body mass index, operative time, and length of stay remained similar. Overall, there were 105 (7.9%) complications: Clavien grade 1 (n = 81, 6.1%) and grade 2 or higher (n = 23, 1.8%). Procedure duration, blood loss, surgeon, year of procedure, laterality, body mass index, age, and gender did not significantly predict complications. There was no significant difference for Clavien complication rates between the early learning period (first 150 cases) and the rest of the series. CONCLUSION: With continual refinement with LDN techniques based on intraoperative observations and technological advances, complication rates remain consistently low, despite increasing donor age.
