It seems that you have a hard calcium stone as the soft stoes would not show up on this type of Xray. People have written of the various ways they reduce the size of these hard stones before doing LFs. H. Clark's kidney cleanse dissolves calcium stones in the bile system and kidneys. Moritz's method uses malic acid to soften stones. Some people are using Pulverex or gold coin grass. It may help to change your diet to keep your body slightly alkaline rather than more acid.
