Hyperreninemia during renal transplantation.
18 patients undergoing renal transplantation were studied prospectively to determine the incidence and mechanism of blood pressure elevations which sometimes occur after release of vascular clamps from the grafts. No patients became as severely hypertensive as noted in previous reports. A weak, but statistically significant (r=0.56, p less than 0.05) positive correlation was found between changes in plasma renin activity and small incremental changes in blood pressure. 2 patients in whom the greatest change in renin occurred showed little or no increase in blood pressure. In view of the small blood pressure changes seen in the face of significant changes in plasma renin activity, it appears unlikely that acute hyperreninemia alone is sufficient explanation for postdeclamping hypertension which is sometimes observed during renal transplantation.
