I have not looked into that.

But a quick search gave me this paper, which claims that kidney stones can be caused by both acidic and alkaline urine -- each causes a different type of stone.

If true, it means there is no way to know if changing the Ph level of the urnine one way or the other would help, unless it is known which type of stones they are.

Even then, is there any research to show that eating a particular type of food causes a direct change of the urine Ph level, which causes destruction of the stones in the human body, as opposed to simply causing such a thing to happen in a laboratory test tube? I don't know the answer to that, but knowning it might be helpful.
