Abstract 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. Keywords Kidney transplantation · Living donors · Nephrectomy · Laparoscopy · Hand-assisted laparoscopy · Obesity Kidney transplantation is the most effective option in treating end-stage renal disease. Due to a persistent shortage of deceased donor organs, living donor kidney transplantation is considered as an excellent alternative to expand the kidney donor pool. Careful selection criteria for living donors are warranted because donor nephrectomy can cause complications, including short-term and long-term, in healthy * Kosei Takagi [email protected] 1
