3 Largest Kidney Stones Ever Removed

Kidney stones are known for being notoriously painful and some women even report that passing a kidney stone is worse than childbirth. As their name suggests, kidney stones are hard deposits of minerals and salt that form inside of a person’s kidneys. They are fairly common and typically can be passed through the urinary tract without any problem.

However, many people have kidney stones that are too big to pass naturally and they need to be broken up or removed through surgery. On average these kidney stones that can’t be passed naturally are only a few millimeters in diameter, but all of the kidney stones on this list dwarf those stones by several centimeters. The largest stone ever removed is over half a foot in diameter!

Stone Urological Research Institute, were officially added to the record books in 2005.

Since the kidney stone was so large, Ghuge’s surgery took four hours to perform. Ghuge’s kidney stone was broken up into smaller pieces using a laser and a minimal invasive technique.
