Dual Kidney Transplantation (DKT) has been developed to improve outcomes from transplantation based on extended criteria of donors (ECD) and demonstrated excellent short-term outcomes. We performed DKT at Samsung Medical Center in March 2021. The donor was a 74-year-old male with no history of known underlying diseases but died from traumatic subarachnoid hemorrhage. The recipient was a 72-year-old male who had been undergoing nephrological observation for 4 years prior to the kidney transplant. The patient had been on hemodialysis since July 2017 and had been suffering from type 2 diabetes since 2003. On non-contrast computed tomography, diffuse calcific atherosclerosis was observed in the abdominal aorta and left iliac artery. As a result, ipsilateral DKT was performed. Because of this diffuse calcific atherosclerosis, we planned ipsilateral DKT on the right side. Postoperative healing was uneventful without complications. In conclusion, DKT is an option for improving survival in the ECD pool, and ipsilateral DKT can be helpful option for preventing organ discard in ECDs.
