Do all stones require surgery?
No. There are several variables, which affect a person’s ability to completely pass a kidney stone. Some stones can pass spontaneously without medical or surgical intervention. The size and the location of the stone are factors that may effect whether a stone will pass spontaneously. Stones that are smaller than 4 mm have a 40-fold greater chance of passing spontaneously than for stones larger than 6 mm, regardless of the location of the stone.
