CNN —The world’s largest kidney stone has been removed from a patient in Sri Lanka – and it’s about the size of a grapefuit, as long as a banana and as heavy as four hamsters. Guinness World Records has confirmed that both records have been broken by the Sri Lankan stone, removed at the Colombo Army Hospital. Kidney stones consist of solid pieces of material that crystallize in the kidney, ureters or bladder due to genetic and environmental factors. A 2018 study suggested that the prevalence of kidney stones is increasing among both men and women in the United States. In order to confirm a diagnosis of kidney stones, physicians may use imaging techniques such as ultrasound or computed tomography (CT) scans.
