Paediatric aspects of renal transplantation: experience of a single centre.

From 1970 to 1991 a total of 244 renal transplantations were performed in 203 children at the Medical School in Hannover. The mean patient age was 10.4 years with a range between 11 months and 16.9 years. Fifty-nine children received a living donor graft from one parent and 144 received cadaveric grafts. Forty-two children were transplanted without prior dialysis treatment. After 20 years the overall survival rates were 86% for the patients and 39% for the first grafts. Grafts from donors below 5 years of age had a less favourable survival (44% after 5 years). Pre-emptive transplantation yielded comparable results with the benefit of a shorter period of uraemia. Hypertension developed in 80% of transplanted patients. Only children with living related donor grafts had significantly less hypertensive problems independent of the immunosuppressive regimen. Post-transplantational growth improved under cyclosporin. Children with nephropathic cystinosis also showed catch up growth after transplantation under cyclosporin. The long-term outcome and rehabilitation of grown-up recipients were encouraging.
