A mother is due to donate one of her kidneys to her 19-year-old-daughter in a live transplant.
Kirsty and Kathryn Fleet will be taking part in a live transplant
Kathryn Fleet, 42, from Tredegar, Blaenau Gwent was found to be a match for Kirsty, a student in Swansea, after she suffered renal failure in April.
It is set to be the 100th transplant performed at the University Hospital of Wales in Cardiff this year.
Kirsty said she was excited to be getting her health back on track and about going back to college.
"I want to get back to university in September and get back to being the normal me," she said.
Kirsty, who is currently on dialysis three times a week, said she became unwell after attending a college ball eight months ago.
"I was violently sick the next day and the following week I just kept being sick and having really bad nosebleeds.
"I came home for Easter and two weeks later I was in hospital hearing I had kidney failure," Kirsty added.
Mrs Fleet described her daughter's diagnosis as a "frightening moment".
"She had a throat infection but she wasn't getting better and she's never normally ill, but she was sleepy all the time and when she was awake she was being sick," Mrs Fleet said.
Kirsty Fleet was told she would have to wait three years for a donor
Her daughter was given a blood test and within hours she was called to the hospital, underwent dialysis and had two blood transfusions.
After they took a biopsy of her kidneys, Kirsty was told they were 70% scarred.
She later learned that rather than having to wait for over three years for a kidney donor she was told of the possibility of having a live transplant.
All members of Kirsty's family, including her father Mark, 21-year-old sister Jodie and 18-year-old brother Joel were compatible as donors, but Mrs Fleet was advised to go ahead with the transplant.
It is expected the whole process will take about 12 hours.
"Mam will go down at around eight o'clock in the morning and the operation will last for around three to four hours," Kirsty said.
"Then they'll call me down just as Mam's out of theatre and then I'll go in because they don't like leaving the kidney outside the body for too long.
"I should be back on the ward by around eight o'clock at night - it's a 12-hour job really," she said.
