Passing a 0.7cm Kidney Stone: Surgery or Natural Passage?

It is unlikely that a 0.7-meter (70 centimeters) kidney stone could be passed without surgery. This would be an exceptionally large stone, much larger than the typical size of a kidney stone, which usually ranges from a few millimeters to a few centimeters. A stone of this size would likely cause significant obstruction and damage to the kidney and would require medical intervention.
