kidney stones and stomach acid

Could there be a link between kidney stones and low stomach acid? One of the natural remedies for kidney stones is lemon juice and olive oil, and I know lemon juice can mimic stomach acid, and I think one of the stomach acids job is to break down minerals, so this seems like a likely assumption to me. And if this were the case, does that mean that getting your stomach acid levels up would help with all stone formation in the body? This is a huge issue for me, so I would appreciate any input that anyone wants to give.
