Surgeons at a hospital in Trincomalee have successfully removed a 3.1-kilogram bladder stone from a 55-year-old paralysed patient, with medical staff suggesting it may rank among the world's largest stones of its kind removed through surgical intervention.

A surgical team at a Trincomalee hospital removed an exceptionally large bladder stone weighing 3.1 kilograms from a 55-year-old patient on August 14. The stone measured between 14 and 19 centimetres in length, according to doctors involved in the operation.

The patient, who is paralysed, was initially admitted to the hospital approximately one month prior after scans detected what appeared to be a mass in the abdominal region. Subsequent diagnostic investigations determined that the mass was a substantial bladder stone rather than another condition. A team of specialists then prepared the patient for surgical removal.

The hospital director stated that the extracted stone may potentially qualify for recognition as a Guinness World Record for the largest bladder stone removed surgically, though official confirmation from the record-keeping organisation has not yet been obtained. The director emphasised the contribution of the specialist physician and medical team in successfully completing the procedure, while noting that institutional support through provision of facilities and equipment was also instrumental to the operation's success.

Medical literature typically documents bladder stones as relatively uncommon complications that can develop over extended periods, particularly in patients with limited mobility or certain urological conditions. The size of this particular specimen has drawn attention from medical professionals as an unusually large example of such a condition.
