@burcidi-- Not only is alcohol diuretic, but it also reduces the excretion of uric acid from the body. I'm not a doctor but I think that alcohol is best avoided by those who are at risk of kidney stones.
Treatment of kidney stones is not very difficult. The body usually takes care of it itself. There are also herbal remedies that can relieve pain and quicken the process of passing kidney stones. I don't think alcohol will help. If anything, it will probably make things worse because of its effects on uric acid and diuretic properties.
