Surgeons in Sri Lanka successfully removed a 3.1-kilogram bladder stone from a 55-year-old patient in Trincomalee. The operation, conducted at a local hospital, is believed by medical professionals to potentially represent a world record for the largest bladder stone ever surgically removed. The sheer size of the stone is remarkable, highlighting a rare and extreme case. Details surrounding the patient’s condition prior to the surgery have not been widely released. Medical teams are currently compiling documentation to submit for official record verification. This successful procedure demonstrates the capabilities of the Sri Lankan medical system and offers a significant case study for urological research.
