I had lithotripsy on a large stone, 1.6 cm, in my left kidney on 5/23/2014. For about five days now I have been experiencing edema in my lower legs, ankles, and feet. It is progressively worse each day even though it subsides a bit overnight but does not completely resolve. I have never had edema this pronounced before. Could this be a sequelae of the lithotripsy procedure?
