"She wanted life to go back to what it was before her kidneys shut down."
Scot Radcliffe's wife, Gina Ravens, had been waiting four years on the transplant list for a lifesaving organ.
The 62-year-old was receiving dialysis three times a week.
Then, in the early hours of New Year's Day 2017, she got the call she was waiting for – a kidney had become available.
"It was like Christmas Day all over again for her," says Scot. "I was hooking her up to the dialysis machine when the call came in. She started unhooking herself, got dressed and off she went."
Gina headed into hospital in Oxford.
"She was all ready and they said that as soon as they found a bed for her, they would begin prepping her for surgery. They kept coming in every half an hour reassuring her that everything would be fine," said Scot.
But later that afternoon Gina got some devastating news.
"They came in and said they couldn't find a bed for her and she would have to go home."
Gina's transplant was cancelled and as far as they understood, the organ went to waste.
Oxford University Hospitals NHS Foundation Trust said it could not comment on individual cases but told 5 Live Investigates that "decisions taken about any individual patient's care are taken in the best interests of that patient by the clinicians who are looking after them".
It added that the majority of transplants last year did not require an intensive care bed and it is used to accommodating increasing numbers of transplants.
For Scot, the thought that a donated organ was not used is something he finds extremely difficult.
"I can't help but think the family who donated the kidney would be devastated just as much as I was, if not more so."
Although rare, Gina's case is not unique.
Prof Nizam Mamode is chairman of the chapter of surgeons, at the British Transplantation Society. He told the programme that the transplant service is "more than creaking".
He says availability of intensive care beds, difficulty accessing operating theatres, staff shortages and the provision of out-of-hours services are putting additional pressures on a service struggling to keep up with demand.
"I think it really is at breaking point. I don't think people can continue for much longer working on this basis and I think it really needs some urgent action.
"There's been a huge success in transplantation. The number of transplants has increased by about 50% over the last eight to 10 years, but the workload has gone up for everybody."
Prof Mamode said that the transplants team was under "very, very significant" stress, with surgeons regularly working extremely long shifts without a break.
As of next year, adults in England will be considered potential donors unless they chose to opt out or are excluded.
But an impact assessment carried out by NHS Blood and Transplant (NHSBT) obtained by the Guardian newspaper and seen by the BBC found that the system is already under pressure.
It found organ retrieval staff are experiencing "extreme stress". And it added that while it will take several years before the full impact of the changes will be felt, "transplant capacity is already struggling to meet demand in some units".
A Welsh government spokesperson said there have been rare occasions when organs could not be retrieved because of lack of capacity but everything possible was done to avoid that happening.
They added that they were working with NHSBT and hospitals across the UK "to ensure opportunities for organ donation and transplantation are maximised within existing resources".
Meanwhile, the Scottish government said the capacity issues facing parts of the NHS in England are "not replicated in Scottish transplant units" but continues to monitor the situation closely, adding it is "very rare in Scotland for a transplant unit to decline an organ due to capacity issues".
In Northern Ireland, people currently opt in to organ and tissue donation.
Prof Mamode says the change in legislation in England is good news for patients, but capacity issues are already having an impact.
"We are aware of some cases across the country where, because of lack of capacity, an organ ends up not being transplanted because once you get to a very long time, the organ now is no longer suitable to be transplanted – that's a rare event but that has happened."
