Nonobstructing kidney stone measuring 0.7 cm. is that too big to pass or will i need surgery?

Lithotripsy: The stone may be too big pass on its own. Discuss with your doctor if you may be a candidate for lithotripsy. The procedure uses sound waves to break up the stone so that the fragments may pass in the urine.

Kidney stones: It really depends on where this stone is. Inside the kidney, it will probably stay put. In the ureter it is likely to cause pain and suffering. In the bladder, it will sit. Stones today rarely are treated with surgery, but instead use non-invasive sound waves to fracture the stone into fragments that can pass easily.
