Outcomes and Cost Comparison of 3 Different Laparoscopic Approach for Living Donor Nephrectomy: A Retrospective, Single-Center, Inverse Probability of Treatment Weighting Analysis of 551 Cases.

Background: At our institution, we switched from hand-assisted retroperitoneal laparoscopic donor nephrectomy (HRN) to hand-assisted transperitoneal laparoscopic donor nephrectomy (HTN); we later switched to standard retroperitoneal laparoscopic donor nephrectomy (SRN). This study was performed to evaluate outcomes and hospital costs among the 3 techniques.
Methods: This retrospective, observational, single-center, inverse probability of treatment weighting analysis study compared the outcomes among 551 cases of living donor kidney transplantation between 2014 and 2022.
Results: After the inverse probability of treatment weighting analysis, there were 114 cases in the HRN group, 204 cases in the HTN group, and 213 cases in the SRN group. Donor complication rates were lowest in the SRN group but did not differ between the HRN and HTN groups (1.1 vs 4.4 and 5.9%, P = .021). Donors in the SRN group had the lowest serum C-reactive protein concentrations on postoperative day 1 (4.3 vs 10.5 and 7.8 mg/dL, P < .001) and the shortest postoperative stay (4.3 vs 7.4 and 8.4 days, P < .001). Donors in the SRN group had the lowest total cost among the 3 groups (8868 vs 9709 and 10,592 USD, P < .0001). Donors in the SRN group also had the lowest costs in terms of "basic medical fees," "medication and injection fees," "Intraoperative drug and material costs," and "testing fees." Furthermore, the presence of complications was significantly correlated with higher total hospital costs (P < .001).
Conclusion: SRN appeared to have the least invasive and complication, and a potential cost savings compared with the HRN and HTN.
