Estenosis de arteria renal en riñón único funcionante

Renal artery stenosis in single kidney is associated with an increase in morbidity-mortality. There is currently a dilemma on its treatment, on if it is better to perform a conservative treatment or revascularization. We present the case of a 72 year old woman with arterial hypertension, without episodes of acute pulmonary edema, right single functioning kidney and right renal artery stenosis, in which it was decided to perform conservative treatment given the control of the blood pressure with drug treatment and because she had maintained stable kidney function in the last year. The literature is reviewed and its treatment discussed.
