(CNN)Surgeons have removed a kidney weighing 7.4 kilograms (16.3 pounds) -- the equivalent size of two newborn babies -- from a patient in India.
Doctors remove giant kidney weighing 16.3 pounds
It is thought to be the heaviest kidney ever removed in the country -- and the third heaviest worldwide.
The patient, a 56-year-old male from the Indian capital New Delhi, suffers from autosomal dominant polycystic kidney disease (ADPKD).
A genetic condition, it causes cysts to develop in the kidneys.
The surgery, which took place at the Sir Ganga Ram Hospital in New Delhi towards the end of October, lasted about two hours, with the removal of the organ itselft taking 30 minutes.
It is not unusual for patients with ADPKD to develop large kidneys, but Dr. Sachin Kathuria, consultant of urology at the hospital and the lead surgeon for the operation, said this was the biggest he has seen.
"Based on our knowledge, this is the third heaviest that has been removed," Kathuria told CNN.
"One in the US was 9 kilograms (19.8 pounds) and the other in the Netherlands... was 8.7 (19.2 pounds). We believe it is the largest that has been removed in India," he added.
The decision to operate was made after the patient complained of ongoing pain and increasing kidney failure.
"The patient was suffering from kidney failure, flank pain (and) infections that were not responding to medication because the antibiotics weren't able to penetrate the cysts.
"The cysts were at risk of haemorrhaging, which can lead to uncontrolled bleeding. He was having trouble breathing because of the size of the kidneys pressing into other organs," said Kathuria.
