A team of doctors of the Sri Lanka Army surgically removed what is considered to be the largest and heaviest kidney stone from a patient on June 01.
At the Army Hospital in Colombo, they removed the calculus that is 13.372 cm long and weighs 801 g.
The previous record for the largest (13 cm) kidney stone was held by India and the heaviest (620 g) by Pakistan.
Head of the hospital’s genitourinary unit Lt. Col. Dr. K. Sutharshan led the surgery, assisted by Capt. Dr. W.P.S.C. Pathiratne, Dr. Thamansha Prematilake, and two colonels, Dr. U.A.L.D. Perera and Dr. C.L. Abeysinghe, as anesthetists.
Later, army chief Lt. Gen. Vikum Liyanage was shown the kidney stone that has now entered the Guinness World Records.
