The death of a foreign tourist brought new life for Yiu Yuk-ki. A kidney taken from the tourist was transplanted into the teenager, who celebrates her 14th birthday on Thursday freed from dieting, limited mobility and long hours on dialysis. Yuk-ki, who was born with abnormally small kidneys, has had hormone injections every day since she was five. But her condition worsened and for the past five years she has needed 10 hours of dialysis every night. She could not go swimming (her favourite exercise), eat hamburgers or even watch television with her sisters in the living room. But a tragedy in September, when a western tourist had a massive stroke at the airport while transferring to a Beijing flight with a relative, changed things. He was taken to Princess Margaret Hospital and six days later was confirmed brain-dead. With the encouragement of the hospital's transplant co-ordinator, a veteran nurse, a relative agreed to donate his organs. The hospital immediately arranged a series of tests on the donor and contacted potential beneficiaries, including Yuk-ki, who rushed to the hospital with her mother. Three patients were saved after two kidneys and one liver were donated. 'The donor's relative was particularly happy that the donations could help save such a little girl's life,' said transplant co-ordinator Monica Wong Wing-kan. To protect the donor's privacy, she declined to disclose his nationality and age. The donor's body has already been sent back to his home country. 'He was very great,' Yuk-ki said, relishing the thought of freedom to see more of the world. 'I seldom went out after school because I had to have dialysis at home. I could not even watch TV with my sisters at night because the dialysis machine was in my bedroom. But now I don't need to have dialysis any more.' Still, Yuk-ki must remain under careful observation for six months. 'I hope more people will donate their organs after death so that patients like me can be saved,' she said, adding that she wanted to become a nurse one day and take care of other patients. According to the Hospital Authority, there are more than 1,300 patients in Hong Kong who need kidney transplants and about 140 in need of liver transplants.
