Abstract

Objective: To compare surgical outcomes between living kidney donors with a single renal artery (SRA) and those with multiple renal arteries (MRA) undergoing transperitoneal laparoscopic donor nephrectomy (LDN) at a Vietnamese transplant center. Subjects and Methods: A retrospective descriptive study was conducted on 170 living kidney donors who underwent transperitoneal LDN at the Organ Transplantation Center, Viet Duc University Hospital, from January 2023 to June 2025. All donors were evaluated by multislice CT angiography and divided into two groups: SRA (n = 143) and MRA (n = 27). Clinical data, vascular anatomy, surgical variables, and reconstruction techniques were collected and analyzed. Results: No significant differences were found between groups in age, gender, BMI, or preoperative GFR. Mean operative time, warm ischemia time, and trocar usage were comparable (p > 0.05). The MRA group had significantly greater intraoperative blood loss (31 ± 14 ml vs. 12 ± 7 ml; p < 0.001). All MRA grafts required arterial reconstruction (78% unification, 19% dual anastomosis), while no prosthetic grafts were used. No intraoperative or postoperative complications were reported in either group. Conclusion: Laparoscopic donor nephrectomy in living donors with multiple renal arteries is feasible and safe when performed by experienced surgeons. Surgical outcomes are comparable to single-artery donors, supporting the inclusion of MRA donors in living kidney transplant programs.
