Sumario:Patient: Male, 30-year-old Final Diagnosis: End stage renal disease secondary to hypertensive nephropathy Symptoms: Uremic symptoms Medication:— Clinical Procedure: — Specialty: Transplantology OBJECTIVE: Rare disease BACKGROUND: En bloc pediatric kidneys (EBPK) are one potential solution to increase the number of organs available in the donor community, thus promoting transplantation of these allografts into adult recipients. However, EBPK transplantation has been traditionally considered suboptimal due to concerns for perioperative complications, mainly vascular thrombosis. We report an en bloc kidney transplantation using vascular grafts from another deceased donor to extend the EBPK aorta and vena cava and create a tension-free anastomosis with recipient external iliac vessels. CASE REPORT: A pair of 2-month-old female en bloc kidneys weighting 6 kg were transplanted to a 30-year-old adult male. Prolonged cold ischemic time (CIT) was related to high refusal rate and long travel from Nevada to Miami. Prior to transplantation, the EBPK were connected to the LifePort Renal Preservation Machine(®) and deemed transplantable only after showing a significant improvement in perfusion parameters. Back-table reconstruction was conducted through an end-to-end anastomosis between an adult deceased donor common iliac artery and vein grafts to the inferior vena cava and aortic distal ends, respectively. The patient displayed immediate graft function (IGF) without any postoperative complications, showing a creatinine of 1.5 mg/dl at 4-month follow-up. CONCLUSIONS: Use of renal preservation machine (RPM) and refined back-table reconstruction of these allografts are important tools to improve the significant discard rate and improve outcomes of EBPK.
