A 3.1kg bladder stone was surgically removed last week at a hospital in Trincomalee from a 55-year-old man, and doctors say it is the largest ever documented.
The stone was discovered after the patient—hospitalized following a stroke—developed difficulty urinating, prompting scans that found stones in his bladder.
At about 17cm wide, the mass was roughly the size of an ostrich egg and far exceeded the threshold for a “giant” bladder stone, which is larger than 4cm.
Doctors said the stone may have been in the bladder for five to 10 years; the patient remains hospitalized for other conditions but is in very good health after surgery.
The previous Guinness-listed record was a 1.9kg bladder stone removed in Brazil in 2003, making the Sri Lankan case markedly heavier though slightly shorter.
