A Single Center Experience With Adult Dual Kidney Transplant

Objectives: Our renal transplant center in South Australian has been at the forefront of dual kidney transplants in Australia. In this study, we reviewed the 17 adult dual kidney transplants performed at our center between 1998 and 2014. Materials and Methods: We retrospectively reviewed the 17 adult dual kidney transplants performed at our center since 1998 and report data pertaining to donor demographics, preimplant function, and histology of donor kidneys, as well as postoperative outcomes of transplant recipients. Results: The mean age of donors was 68.5 ± 7.27 years, with 47% presenting with comorbid disease adversely affecting renal function (diabetes or hypertension). Histologic sampling of donor kidneys showed high rates of glomerular obsolescence, scarring, and vascular sclerosis. The mean age of recipients was 57.18 ± 10.93 years, with 10 patients receiving kidneys that were implanted bilaterally in each iliac fossa and 7 patients having both kidneys implanted into 1 iliac fossa. Early surgical complications (within the first 2 wk) were found in 6 patients (4 bilateral, 2 unilateral). In patients with bilaterally placed grafts, 2 developed a urinary leak, 1 lost both grafts secondary to renal vein thrombosis, and 1 lost a single graft due to renal vein thrombosis. In patients with unilaterally placed grafts, 1 had wound infection and 1 had double graft loss related to renal vein thrombosis. Conclusions: Adult dual kidney transplants offer an alternative use of kidneys from marginal donors.
