[Hypertension following renal transplantation (author's transl)].

Hypertension is more frequent in transplant recipients than in the general population. The two most frequent causes are reduced function of the transplant and the presence of the recipient's own kidneys. Beyond the immediate postoperative period, administration of glucocorticoids appears to have little influence on blood pressure. The various forms of arterial stenosis of the transplant are infrequent, but clinically important, because they are susceptible to surgical correction or arterial dilatation. The pathogenetic mechanisms and diagnostic problems of the various forms of posttransplant-hypertension are discussed in this review.
