Kidney transplantation is ideal for children and adolescents with chronic end-stage renal disease because it offers better growth, development, and quality of life. Donor choice is vitally important in this age group, given the long life expectancy of these patients. A retrospective analysis of pediatric patients (<18 years) who underwent kidney transplantation from January 1999 to December/2018 was performed. Short- and long-term outcomes were compared between living and deceased donor transplants. We included 59 pediatric kidney transplant recipients, 12 from a living donor and 47 from a deceased donor. Thirty-six (61.0%) patients were boys, and 5 (8.5%) had a retransplant. There were no differences between groups on sex, race, and weight of the recipient and donor, as well as the age and the etiology of the recipient's primary disease. Most recipients received induction immunosuppression with basiliximab and maintenance with triple therapy, with no differences between groups. Living donor transplants were mostly pre-emptive (58.3% vs 4.3%, P <.001) and had fewer HLA mismatches (≤3: 90.9% vs 13.0%, P <.001), older donors (38.4 vs 24.3 years, P <.001) and shorter hospital stays (8.8 vs 14.1 days, P =.004). There were no statistically significant differences regarding medical-surgical complications and graft or patient survival. However, we found that at 13 years post-transplant 91.7% of the living donor grafts were functioning vs 72.3% of the deceased donor grafts. Our experience points out that a living donor graft in pediatric patients is associated with a higher probability of pre-emptive transplant, shorter hospital stay, greater HLA compatibility, and increased graft survival.
