[Choice of donor and the results of renal grafting (author's transl)].

For the calculation of the donor influence on the results of renal grafting, all non-renal causes of transplant failure must be excluded. The following criteria for the selection of a suitable kidney donor were found: the urine production of the donor in the last hour before nephrectomy should amount to at least 200 ml and the age difference between donor and recipient should be not more than 20 years. Proteinuria, a high serum creatinine level, vascular anomalies and a long operation time for vascular anastomosis were unfavourable. The preservation time, the warm ischemia time and the sex of the donor have little effect. If no rejection crises occurred within the first 3 weeks after transplantation, the transplant survival rate increased from 45% to 71%.
