The most common anatomic variant seen in donor kidneys for renal transplantation
is the presence of multiple renal arteries, which can cause an increased risk of
complications. Accessory renal arteries should be anastomosed to the proper
source arteries to improve renal perfusion via the appropriate vascular
reconstruction techniques. In microsurgery, 2 kinds of vascular augmentation
methods, known as 'supercharging' and 'turbocharging,' have been introduced to
ensure vascular perfusion in the transferred flap. Supercharging uses a distant
source of the vessels, while turbocharging uses vascular sources within the same
flap territory. These technical concepts can also be applied in renal
transplantation, and in this report, we describe 2 patients who underwent
procedures using supercharging and turbocharging. In one case, the ipsilateral
deep inferior epigastric artery was transposed to the accessory renal artery
(supercharging), and in the other case, the accessory renal artery was
anastomosed to the corresponding main renal artery with a vascular graft
(turbocharging). The transplanted kidneys showed good perfusion and proper
function. No cases of renal failure, hypertension, rejection, or urologic
complications were observed. These microsurgical techniques can be safely
utilized for renal transplantation with donor kidneys that have multiple arteries
with a lower complication rate and better outcome.
