Little did the team of Sri Lankan doctors know that after they were done removing a kidney stone from 62-year-old retired soldier Canistus Coonghe's abdomen, they would have a world record holder in their hands. Quite literally.

The massive kidney stone has set the world record for both the largest and the heaviest kidney stone to have been ever removed from a human body, as per a press release by the Sri Lanka Army. The colossal ball made up of excess minerals and salts is 13.372 cm long and weighs 801 g.

As you can see in the photo above, it looks like a big turnip that has been rotting in the ground for a couple of years.

The stone was larger than the patient's kidney

The stone was larger than Coonghe’s actual kidney, with a bipolar length of 11.8 cm.

The surgery occurred on June 1 at the Colombo Army Hospital in Colombo, Sri Lanka. As per the existing Guinness World Records, the largest kidney stone found in the world (India in 2004) was 13 cm and the heaviest kidney stone found (Pakistan in 2008) was 620 g in weight.

The previous record holder for the largest kidney stone was an Indian man named Vilas Ghuge, who had a 13 cm kidney stone surgically removed in 2004. And the previous record for the world’s heaviest kidney stone was held by Pakistan’s Wazir Muhammad, who had a 620 g stone removed in 2008, as per the Guinness World Records.

Usually, the size of a kidney stone ranges from a granule to a pebble. But as we can see, sometimes they can grow much larger due to a high level of certain minerals in a person’s urine. Kidney stones can form in one or both kidneys and rarely cause permanent damage.

A sharp pain in the back, lower or side abdomen, and blood in the urine are some of the symptoms to watch out for. Sometimes the size of the kidney stone is so small that it may easily pass through the urinary tract, and the person wouldn’t even get to know it. Not in Coonghe’s case, however.

He underwent a procedure called open pyelolithotomy, in which the stone is removed from within the renal pelvis or from the ureter. He’s now recovering and doing well, as per Guinness World Records.
