How can i encourage my kidney stone to pass by september 2014?

Unpredictable...: Some 85% of stones may pass through ureter in some 2 weeks if its size is 4 mm or less. This does not mean smaller stone always passes or bigger one always never passes. Yet, not all stones will move out of kidney; it is unpredictable. So, who knows? Ask your doctor. Note: more than 95% of kidney stones are not dissoluble with drugs although possible for those few but still very time-consuming...
