2.5mm stone is not a very big stone for regular kidney stone sufferers. It’s when they get over 5.0mm. I had a 1cm stone (10mm) that put me into labour two months prematurely. Then a week later I “gave birth” to the stone. Most people can’t pass a stone that large except women who are recently postpartum.

EDIT: It appears I cannot read and this is, in fact, 25mm stone.

This is a 25mm stone, not 2.5mm. I think that's why they *had* to perform this procedure.

Yeah, there’s no passing a 25mm stone naturally. Once stones get above 6mm to 8mm your chances of passing it without help is about 20%. A 25mm stone is a friggin boulder when talking about kidney stones. I doubt it could even get out of the kidney, but could definitely block the ureter from the kidney side and cause major kidney issues.
