Results of surgery in hypertension due to renal artery stenosis.

We have previously reported our exeriene on the detection af renovascular hypertension, a combination of intravenous 3yelography and isotope renography being used as a screening procedure in hypertensive patients (Kennedy et al., 1965; Luke et al., 1966). In this paper we give an account of the effect of surgical treatment in the 27 patients with renal artery stenosis operated on up to May 1966, so that the minimum follow-up period was at least one year. These 27 patients originated from group of 41 with functional renal artery stenosis found by screening about 1,000 patients with hypertension. We shall report separately the results of surgery in the slightly greater number of patients with unilateral chronic pyelonephritis and other forms of unilateral parenchymal renal disease originating from the same group of hypertensive patients.
