    Abstract:
    The effect of revascularization on decreased glomerular filtration rate (GFR) was studied in 18 patients with renovascular hypertension (RVH) for a period of 5 to 74 months after operation. Renal artery stenosis (SRA) was present unilaterally in 3 patients, bilaterally in 13 patients, and in two patients with one kidney. Following surgical correction, the GFR increased or normalized in 6 patients, decreased in 2, and did not change in 10 patients. The blood pressure of almost 90% of the operated patients normalized or improved. The results support the assumption that severe hypertension is indicated for surgery, irrespective of the magnitude of GFR decrease. Revascularization effected a reversal of renal insufficiency only in a third of the patients.
