Early outcome in renal transplantation from large donors to small and size‐matched recipients – A porcine experimental model. :  Kidney transplantation from a large donor to a small recipient, as in pediatric transplantation, is associated with an increased risk of thrombosis and DGF. We established a porcine model for renal transplantation from an adult donor to a small or size‐matched recipient with a high risk of DGF and studied GFR, RPP using MRI, and markers of kidney injury within 10 h after transplantation. After induction of BD, kidneys were removed from ∼63‐kg donors and kept in cold storage for ∼22 h until transplanted into small (∼15 kg, n = 8) or size‐matched (n = 8) recipients. A reduction in GFR was observed in small recipients within 60 min after reperfusion. Interestingly, this was associated with a significant reduction in medullary RPP, while there was no significant change in the size‐matched recipients. No difference was observed in urinary NGAL excretion between the groups. A significant higher level of HO‐1 mRNA was observed in small recipients than in donors and size‐matched recipients indicating cortical injury. Improvement in early graft perfusion may be a goal to improve short‐ and long‐term GFR and avoid graft thrombosis in pediatric recipients.
