Sri Lankan military doctors have removed what is now recorded as the world's largest kidney stone from a 62-year-old retired soldier, the army said on Wednesday .
The stone removed from ex-sergeant Canistus Coonge weighed 801g, more than five times the weight of an average male kidney, the army said. Mr Coonge's kidney stone measured 13.37cm long, compared to an average kidney stone which is about 10 to 12cm long. "The removal of the world's largest and heaviest kidney stone through a major surgery occurred on June 1 at the Colombo Army Hospital," the military said in a statement.
Mr Coonge told the local Swarnavahini TV that he had abdominal pain since 2020 and oral medication had not helped.The Sri Lankan case surpassed the largest kidney deposit previously recorded of 620g from a patient in Pakistan in 2008, according to Guinness World Records."The most important thing for us is that the kidney is functioning normally despite this stone," army surgeon K. Sutharshan said.
