A 17-year-old boy was released from a Beijing hospital on Monday after successful surgery to transplant one of his mother's kidneys, Beijing News reported on Tuesday. Feng Jiong, who was diagnosed with uremia at 15, was found lying on the street outside a hospital in Beijing on Sept 25 by Lin Jia, a 59-year-old woman. Lin helped take care of him and initiated a donation drive. About 580,000 yuan ($95,860) was raised in donations, part of which was used to bring his mother to Beijing.
