Background: Double kidney transplantation allows the use of marginal kidneys with a significant improvement in the recovery of renal function expected after transplantation, although with a greater anesthesiologic and surgical risk. One-sided positioning, more cautious in the event of functional exhaustion, can be complex due to vascular anomalies. Materials and methods: We report the case of 2 double unilateral kidney transplants with vascular reconstructions. The first is a double kidney transplant from a 83-year-old donor. Both kidneys (score 5) had 2 arteries and the arterial patch was not usable. A cryopreserved arterial graft was used for the packaging of an arterial axis with which a single T-L anastomosis was performed; the 2 veins were also joined with the packaging of a single anastomosis. The second case is a double kidney transplant from a cadaveric donor performed on a recipient suffering from severe diffuse atheromasia. The right kidney had 2 arteries and the left kidney had 3 arteries (both score 5). The aortic patches and veins of the 2 kidneys were joined together and a single arterial and venous anastomosis was performed. Results: The course has been uneventful. In both cases there were no perioperative vascular complications. Conclusions: The use of marginal organs is an increasingly common reality. Bench vascular reconstructions can further increase donation resources, safely enhancing the transplantation of already marginal organs that would otherwise not be usable and allowing the contralateral vascular axis to be kept intact.

Abstract

Background: Double kidney transplantation allows the use of marginal kidneys with a significant improvement in the recovery of renal function expected after transplantation, although with a greater anesthesiologic and surgical risk. One-sided positioning, more cautious in the event of functional exhaustion, can be complex due to vascular anomalies. Materials and methods: We report the case of 2 double unilateral kidney transplants with vascular reconstructions. The first is a double kidney transplant from a 83-year-old donor. Both kidneys (score 5) had 2 arteries and the arterial patch was not usable. A cryopreserved arterial graft was used for the packaging of an arterial axis with which a single T-L anastomosis was performed; the 2 veins were also joined with the packaging of a single anastomosis. The second case is a double kidney transplant from a cadaveric donor performed on a recipient suffering from severe diffuse atheromasia. The right kidney had 2 arteries and the left kidney had 3 arteries (both score 5). The aortic patches and veins of the 2 kidneys were joined together and a single arterial and venous anastomosis was performed. Results: The course has been uneventful. In both cases there were no perioperative vascular complications. Conclusions: The use of marginal organs is an increasingly common reality. Bench vascular reconstructions can further increase donation resources, safely enhancing the transplantation of already marginal organs that would otherwise not be usable and allowing the contralateral vascular axis to be kept intact.
