The family donating kidneys to their siblings

"When people say to you, 'what have you done in your life?' I can at least fall back on this and say I've saved someone's life."

In December Christopher Schuman, from Reading, donated his kidney to his brother Jeremy, who believes he was at "death's door".

This act of kindness was far from unique for their family, as in 2011 their brother Philip gave one of his kidneys to their sister Susan.

In the Schuman family of eight, two of the children inherited polycystic kidney disease, which meant in time their kidneys would fail.

The family returned to the Churchill Hospital in Oxford, where they underwent their life changing operations.

The hospital has done more living kidney donor transplants than any other in the UK, carrying out 68 last year.

The family reunion marks World Kidney Day - a global campaign aimed at raising awareness of the importance of our kidneys.

"I would have had to go onto dialysis, I was down to 4% to 5% function of my kidney," said Susan, when remembering the impact of the disease on her health.

She said she was "exhausted" and needed medication to increase her hemoglobin, because she was suffering with anemia - a common complication of chronic kidney disease.

"It's without doubt, I can say without hesitation, the best thing I've ever done," says Philip, who now lives in America, and joined his relatives virtually.

"I was thinking maybe it's a good chance to always get a good Christmas present from the person," he joked.
