A man whose kidney's have grown to a 'record-breaking' size is preparing to have them removed before they kill him.
Warren Higgs, from Windsor, has polycystic kidney disease (PKD) which causes cysts to develop on his kidneys.
The organs have grown so large they are beginning to crush his heart, lungs and stomach, with his left kidney measuring 42cm (16ins) by 27cm (10.6inch) and his right kidney measuring a potentially record breaking 49cm (19.2ins) by 28cm (11ins).
Doctors believe Warren Higgs' kidneys could weight three times more than one removed from a man in India, which weighed 7.4kg (16.3lb)

What is Polycystic Kidney Disease (PKD)
Polycystic Kidney Disease (PKD) is a genetic disorder in which fluid filled sacs, called cysts, grow on the kidneys.
Signs and symptoms of the disease include high blood pressure, headaches, abdominal pain, blood in the urine, excessive urination and back pain.
There are currently no approved treatment or therapies to prevent the progression of the disease.
The 54-year-old said the inherited condition first became an issue for him at the age of 35 when it caused an aneurysm leading to a stroke which has left him paralysed on his right size.
Five years ago, the father-of-one's kidney's started to grow and are now five times bigger than they should be.
The high-risk operation to remove the kidneys is scheduled for July.
Following the procedure, he will need to be on dialysis while awaiting a transplant.
Mr Higgs, who previously enjoyed taking part in triathlons, is now fundraising in the hope that he will raise enough money to pay for an electric recumbent tricycle to improve his fitness and 'get his life back' following the operation.
The condition has completely changed his life, leaving him with breathing difficulties and being unable to move.
'Considering your kidneys are meant to be the size of a clenched fist, mine are massive,' he told the BBC.
'They're crushing my lungs, crushing my stomach, and I know they've just done a recent scan and they're crushing my heart now.
'It's horrible because I can't move. I can't breathe.'
Speaking of his potential record, he said: 'It's not really a record you want to live with, believe me its horrible. PKD has literally taken away my whole life.'

Royal Borough of Windsor and Maidenhead councillor Wisdom Da Costa, who has been involved in the fundraising, said: 'I have been inspired by his kindness, love for life and get up and go, despite suffering increasingly difficult circumstances in life.
'How could you not want to support such a shining light.'
