[Features of renal dynamics among patients with vasorenal hypertension according to rheographic findings]. / Osobennosti pochechnoi gemodinamiki u bol'nykh s vazorenal'noi gipertenziei po dannym reografii.

Preoperative and late postoperative rheonephrographic findings in 23 patients with vasorenal hypertension are reported. Renal rheography was supplemented with a controlled hypotension test. Diagnostic and predictive value of renal rheography and the controlled hypotension test is explained. Indirect evidence of the irreversible nature of renal angiosclerotic changes on the side of occlusive lesion was demonstrated in patients with poor surgical results and a relatively intact contralateral kidney.

The duration of the case history was determined in 16 patients with vasorenal hypertension caused by unilateral lesion of the renal arteries, as well as renal activity in peripheral and reno-venous blood, Tmax and T1/2 according to the findings of renography, and blood flow in the renal artery before and after reconstruction according to the results of intraoperative flow measurement. The set of characteristics obtained was used in prognosing the parameters of arterial pressure (AP) in the postoperative period by means of regression analysis. The relative root-mean-square error in prognosing systolic AP was 15% and diastolic AP 20%. Nomograms for determining AP parameters according to the combination of characteristics were elaborated.
