[|Human|] My uncle was just told by his doctor that he has an aneurysm in the artery that is conneccted to the kindeys.  The doctor told him that he has two options, one is to wait and see what happens, and two to have surgery to repair what has happened.  My uncle is in his 50s and is very over weight and has diabities and has a very poor diet.  Could you tell me how long can an aneurysm last until it bursts and if it does burst what can happen to the body?
[|AI|]  Dear User, aneurysms may have a very slow progression or may rapidly give a rupture, which in the case of renal artery may be lethal. Much depends on diameters of the dilatation. I suppose that it is a mild dilatation, since your doctor recommended following it during the time. But, if it is over 7-10 mm, I recommend being evaluated by a surgeon, also to understand more of its position, etiology, etc. Take care
