Obese living kidney donors: a comparison of hand-assisted retroperitoneoscopic versus laparoscopic living donor nephrectomy
Background: The aim of this study was to examine the difference in outcome between hand-assisted retroperitoneoscopic and laparoscopic living donor nephrectomy in obese donors, and the impact of donor body mass index on outcome. Methods: Out of 1108 living donors who underwent hand-assisted retroperitoneoscopic or laparoscopic donor nephrectomy between 2010 and 2018, 205 were identified having body mass index ≥ 30. These donors were included in this retrospective study, analyzing postoperative outcomes and remnant renal function. Results: Out of 205 donors, 137 (66.8%) underwent hand-assisted retroperitoneoscopic donor nephrectomy and 68 donors (33.2%) underwent laparoscopic donor nephrectomy. Postoperative outcome did not show any significant differences between the hand-assisted retroperitoneoscopic donor nephrectomy group and the laparoscopic donor nephrectomy group in terms of major complications (2.2% vs. 1.5%, P = 0.72), postoperative pain scale (4 vs. 4, P = 0.67), and the length of stay (3 days vs. 3 days, P = 0.075). The results of kidney function in donors after nephrectomy demonstrated no significant differences between the groups. Additional analysis of 29 donors with body mass index ≥ 35 (14.1%) as compared with 176 donors with body mass index 30–35 (85.9%) revealed no significant differences between groups in postoperative outcomes as well as kidney function after donation. Conclusion: Our results show that laparoscopic living donor nephrectomy for obese donors is safe and feasible with good postoperative outcomes. There were no significant differences regarding postoperative outcome between hand-assisted retroperitoneoscopic and laparoscopic donor nephrectomy. Furthermore, the outcome in donors with body mass index ≥ 35 was comparable to donors with body mass index 30–35.
