If renal artery stenosis is found and treated in time, it has no effect on life expectancy. However, some of them were discovered late, and the kidney has shrunk obviously because of stenosis. Generally, there is no need to worry, because people have two kidneys, and one kidney can be intact after problems occur.
However, if one kidney is severely atrophied, irreversible lesions will occur, and patients will have refractory hypertension and even heart diseases because of this kidney. At this time, it is necessary to consider whether to remove the kidney as soon as possible and remove the causes of hypertension. If it is only simple renal artery stenosis, it is necessary to carry out surgical intervention, stent implantation and even bypass surgery in time. At this time, the blood flow will be improved, which has no effect on the patient's life, so don't worry too much.
