Successful Pediatric Kidney Transplantation Into an Adult Recipient: A Case Report.

Area of Science:

• Nephrology
• Transplant Surgery
• Pediatric Nephrology

Background:

• Donor kidney shortages necessitate innovative transplantation strategies.
• Utilizing pediatric donors (up to 5 years) for adult recipients, often transplanted en bloc, is a viable approach.
• En bloc retrieval involves the aorta and inferior vena cava, with anastomosis to the recipient's iliac vessels.

Observation:

• A 3-year-old's kidneys were transplanted en bloc into a 30-year-old man with end-stage renal disease and a history of failed transplant.
• Post-transplantation, the patient experienced normal renal function initially, followed by renal artery stenosis and nephrotic proteinuria.
• Medical interventions managed proteinuria, and despite significant stenosis, renal function remained stable for 7 years.

Findings:

• En bloc transplantation of pediatric kidneys into adult recipients demonstrates high efficacy.
• Graft and recipient survival rates are comparable to those seen in living donor kidney transplantation.
• This pediatric en bloc kidney transplant approach is a successful strategy for managing end-stage renal disease.

Implications:

• This pediatric en bloc kidney transplantation method offers a promising solution to the organ donor shortage.
• It provides a viable alternative for patients awaiting kidney transplants, improving long-term outcomes.
• The study highlights the potential of utilizing young pediatric donors for adult kidney recipients.
