Doctors in Sri Lanka removed a 3.1kg bladder stone from a 55-year-old patient, with the hospital saying it could be one of the largest bladder stones ever removed through surgery.
The surgery was performed last Friday (14 Aug) at Trincomalee General Hospital in Trincomalee.
The patient had been admitted about a month earlier after suffering a stroke.
However, during the treatment, he experienced difficulty urinating.
Further examinations discovered a large stone in his urinary bladder.

A team of specialists then prepared the patient for surgery to remove the stone.
Dr Pahalathan Balakrishnan, who led the surgery, said the removed stone weighed 3.1kg and measured between 14cm and 19cm in length.
The size was comparable to an ostrich egg and its weight to that of a full-term newborn baby, the doctor said.
She credited the specialist doctor and medical team for successfully carrying out the procedure, adding that the hospital administration supported the operation by providing the necessary facilities and equipment.
The stone is estimated to have been in the patient’s bladder for five to 10 years.
Bladder stones typically occur when urine is not fully expelled, becoming concentrated enough for minerals to crystallise into solid lumps.

Although small stones can pass through urine on their own, stones larger than one centimetre can obstruct flow and demand medical care.
Those exceeding four centimetres are typically classified as massive.
The hospital director said the stone could potentially qualify for a Guinness World Record as the largest bladder stone removed through surgery, although this has not been officially confirmed.
According to the BBC, the previous Guinness World Record for the largest bladder stone removed was a 1.9kg stone measuring 17.9cm, removed from a person in Brazil in 2003.
The patient is in good health and will continue to be treated for other medical conditions, said Dr Pahalathan.
