Colombo: Doctors in Sri Lanka have successfully removed a massive 3.1 kg bladder stone from a 55-year-old man, which is believed to be the largest bladder stone ever removed through surgery.
The rare procedure was performed last week at Trincomalee General Hospital in eastern Sri Lanka.
The patient had been admitted to the hospital after suffering a stroke. During treatment, doctors noticed that he was facing difficulty while urinating. Further medical examination revealed the presence of large stones in his urinary bladder.
During surgery, doctors removed the giant bladder stone, which weighed almost as much as a full-term baby and was approximately the size of an ostrich egg.
Dr Prahalahan Balakrishnan, who led the surgical team, said that according to available records, the stone was the largest bladder stone documented and removed through surgery.
Doctors said the patient is currently in good health and remains under medical care for his other health conditions. The surgical team estimated that the stone had been developing inside the patient’s bladder for nearly five to 10 years.
The removed stone measured around 17 cm in length. Doctors explained that bladder stones form when minerals in urine crystallise and turn into hard masses.
Bladder stones usually develop when the bladder does not empty completely, causing concentrated urine to form crystals. While very small stones may pass naturally, larger stones can block urine flow and require medical treatment.
A bladder stone larger than 4 cm is considered a giant bladder stone.
According to Guinness World Records, the previous largest bladder stone was removed from a patient in Brazil in 2003. It weighed around 1.9 kg and measured 17.9 cm in length.
The Sri Lankan case, involving a 3.1 kg stone, could potentially set a new medical record pending official verification.
