[Parameters affecting the results of kidney transplantation. Critical analysis of the literature]

On the basis of a critical analysis of 227 studies reported in the literature it was examined to which extend the results of renal transplantation depend on the age of the recipient, the length of preoperative dialysis treatment, HBs-antigenemia, former pregnancies, preoperative blood transfusions, tissue compatibility and donor age. A negative influence of the recipient's age on the results was found, but nevertheless older patients can be also transplanted. HBs-antigenemia is not a contraindication for transplantation either. Preoperative blood transfusion can improve the graft survival, but the value of intraoperative transfusions is not quite clear. The same applies to donor age, former pregnancies and tissue compatibility.
