Results of renal transplantation using pediatric cadaver donors.

In order to determine the results of transplantation using pediatric cadaver donors, a retrospective analysis of a series of 502 renal transplant recipients was carried out. Methods of procurement, preservation, recipient selection, and immunosuppressive regimen were similar for all patients. Sixty-five recipients were approximately equally divided into three groups whose donors were younger than 5 years of age, 6 to 10 years old, and 11 to 15 years. These three groups then were compared with each other and to a randomly selected representative group of recipients whose donors were adults (16 years or older) for the following parameters: actuarial graft and patient survival, causes of graft failure and patient death, level of serum creatinine in currently functioning grafts, and recipient age. There were no statistically significant differences between groups for any parameter except that the mean age of recipients was approximately 16 years for the donors up to 5 years of age and was between 31 and 36 years for the other donor age groups (P = 0.01). These results support the contention that brain-dead pediatric patients of any age should be considered to be potential cadaveric kidney donors. Exclusion of these patients is very wasteful and also is unnecessary since results of transplantation equal to those obtained with adult donors can be expected. Technical graft failures should not be more frequent than with adult kidneys, and there is no need to modify the basic surgical technique for small kidneys in order to achieve this.
