The Impact of Learning Curve on Robotic Living Donor Nephrectomy Outcomes: Retrospective Analysis
Sarah Papa, Aleksandar Popovic, Reut Hod Dvorai, Rauf ShahbazovABSTRACT
Background
We aimed to investigate the outcome of patients after RDN at different time points.
Methods
We studied the outcomes of 77 living robotic living donor nephrectomies (RDN). Donors were separated into three groups: learning curve period (LCP), stabilisation period (SP), and teaching period (TP).
Results
There were significant differences in blood loss and hospitalisation times between the three groups. Operative time was significantly shorter in the LCP group compared with the SP and TP groups (282 ± 51.6 min vs. 308 ± 38.7 min vs. 314 ± 28.7, p = 0.02). However, warm ischaemia time was shorter in the TP group compared with the LCP and SP groups (5.0 ± 3.6 min vs. 3.4 ± 3.2 min vs. 1.5 ± 1.3 min, p < 0.01). Complication rates were higher in the LCP group compared with the SP and TP groups (p = 0.04).
Conclusion
This study demonstrated that RDN outcomes improve after the learning period.
