Doctors in Sri Lanka recently succeeded in removing a bladder stone weighing about 3.1 kilograms from a patient, exceeding the current Guinness World Record for such a stone, which stands at 1.9 kilograms.
The patient, a 55-year-old male, was admitted to a hospital in Trincomalee, eastern Sri Lanka, about a month ago after suffering a stroke. Doctors discovered he had difficulty urinating, and subsequent examinations revealed the presence of a bladder stone.
The stone removal surgery was performed on the 14th. Measurements showed the stone was about 17 centimeters long and weighed around 3.1 kilograms—about the same as a full-term newborn. Photos released by the hospital show the stone is irregularly oval in shape and about the size of an ostrich egg.
The current Guinness World Record for the largest bladder stone is 1.9 kilograms, removed by doctors from a patient in São Paulo, Brazil, in August 2003.
The lead surgeon for this operation, Balakrishnan, said: "According to existing records, this is the largest bladder stone ever surgically removed."
He estimated that the stone had been present in the patient’s body for 5 to 10 years.
The patient is in good condition after surgery but will need to remain in hospital for further treatment.
