Insights
Pediatric kidney transplantation outcomes in our department mirror adult results, with similar graft survival rates despite higher acute rejection rates in children. This study analyzed 101 pediatric kidney transplants over 35 years.
Area of Science:
- Nephrology
- Pediatric Surgery
- Transplantation Medicine
Background:
- Pediatric kidney transplantation constitutes a small fraction (around 4%) of all kidney transplantations in Europe.
- Understanding the specific outcomes and trends in pediatric renal transplantation is crucial for improving care for this unique patient group.
Purpose of the Study:
- To analyze the evolution of pediatric renal transplantation within our department over a 35-year period.
- To compare the outcomes of pediatric renal transplant recipients with those of adult recipients.
- To identify predictive factors for graft loss and survival in pediatric kidney transplantation.
Main Methods:
- A retrospective analysis of 101 pediatric renal transplantations performed between January 1981 and December 2016.
- Evaluation of clinical, analytical, and surgical data to determine factors influencing graft survival.
- Comparative analysis between pediatric and adult renal transplant populations.
Main Results:
- Pediatric transplants represented 3.4% of all kidney transplants in the department; 12% involved living donors.
- Younger donor age was linked to reduced graft survival, and acute rejections were more common in pediatric recipients.
- One, 5, and 10-year renal graft survival rates were 94.8%, 77.4%, and 66.5%, respectively, with no significant difference compared to adults.
Conclusions:
- Pediatric renal transplantation demonstrates comparable graft survival rates to adult transplantation.
- Despite challenges like higher acute rejection rates, pediatric kidney transplant outcomes are consistent with adult benchmarks.
Background:
In Europe, pediatric transplantation accounts for only about 4% of all kidney transplantations performed. The aim of our work is to evaluate the evolution of pediatric renal transplantation in our department over time, but also to compare this special population with the adult one.
Methods:
We evaluated all pediatric renal transplantations performed in our department between January 1981 and December 2016. We performed the analysis of clinical, analytical, and surgical factors to look for predictive factors of graft loss or decrease of survival. In addition, we performed a comparative study of pediatric and adult populations and an evaluation of the evolution of pediatric renal transplantation in our department over time.
Results:
We evaluated 101 renal transplantations performed in patients younger than 18 years. Pediatric transplantations corresponded to 3.4% of all renal transplantations performed in our department. The rate of living donors was 12%. Donors of grafts for the pediatric population were significantly younger than in the adult population. The increase in donor age was associated with lower renal graft survival rates. Acute rejections were more frequent in the pediatric population. Eleven pediatric recipients (10.9%) died in the follow-up period. Renal graft survival in the pediatric population was 94.8%, 77.4%, and 66.5% at 1, 5, and 10 years, respectively. There was no significant difference in graft survival in the pediatric and adult population. The pediatric overall survival rate at 1, 5 and 10 years was 97.9%, 96.8%, and 91.9%, respectively.
Conclusion:
Pediatric renal transplantation presents results identical to those identified in adults.

Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...
