Doctors in Sri Lanka have removed a 3.1kg (6.8lb) bladder stone from a man - which they believe to be the largest of its kind on record.

The procedure was carried out last week at a hospital in Trincomalee, in the east of the country.

The 55-year-old patient had been admitted to hospital after suffering a stroke. But while receiving treatment, doctors found stones in his urinary bladder after noticing that he was experiencing difficulty urinating.

During surgery, doctors removed the bladder stone - it weighed as much as a full-term baby and was around the size of an ostrich egg.
