I think the olive oil and lemons are just for removal of gallstones and not kidney stones.
For kidney stones, I have a friend that got rid of of one kidney stone by drinking a gallon of cranberry juice a day. He used CRAN-GRAPE from Ocean Spray as the cranberry alone was too bitter for him to drink. (Prior to that he had gone to the E.R. in severe pain and they just put him on an IV with pain killers and hours later sent home pain free but the stone still stuck--was told nothing else they could do for him and that the kidney stone cannot be removed.)
And, another remedy that has also helped another friend of mine is "CHANKA PIEDRA" herb that he buys at a health herbal food store. He makes a large pot of tea with it and drinks as much as possible a day until the stone come out. He's done it twice, and twice he has been successful.
I hope this helps.
