In brief: Diet - kidney stones
Soy can contribute.
Soy contains oxalate, which binds with calcium to form stones. Minimize oxalate-beets, spinach, rhubarb, strawberries, nuts, chocolate, tea, wheat bran, and all dry beans (fresh, canned, or cooked), excluding lima and green. Also: eat low salt, Less than 4 oz meats, high fruit, high veg, 4 liters fluid, 5 tblspns ReaLemon extract, 2 cups Orange J, modest calcium per day.

In brief: Not necessarily.
Soybeans are rich in oxalate, a naturally occurring substance found in many plants and beans.
80% of kidney stones in adults are calcium-oxalate stones. Many people prone to stone formation must avoid oxalate; however, eating oxalate-rich food does not necessarily cause stones to form. I would not avoid soy unless you have a history of stone formation and a workup that shows high urine oxalate.
