Doctors remove a kidney weighing 7.4kg, which is almost two newborn babies from a patient in New Delhi.
A healthy kidney usually weighs between 120-150g.
The patient was suffering from a condition called Autosomal Dominant Polycystic Kidney Disease, which causes cysts to grow all over the organ.
One doctor involved in the operation said large kidneys were common in patients with the disease.
Sachin Kathuria, a doctor from Sir Ganga Ram hospital in Delhi, said doctors generally would not remove the organ unless there were symptoms of infection and internal bleeding, as they were performing at least some filtering functions in the body.
“This patient had contracted a bad infection that was not responding to antibiotics, and the kidney’s massive size was causing the patient breathing difficulties, so we had no choice but to remove it,” he said.
The heaviest kidney according to the Guinness World Records is 4.5kg, although urology journals had records of kidneys that were even heavier than this one. One from the US weighed 9kg while another from the Netherlands was 8.7kg.
Sachin Kathuria said doctors had not decided whether to submit their findings to the Guinness commission as a world record, but they were “considering it”.
