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 was found lying on the street outside a hospital in Beijing on Sept 25 by Lin Jia, a 59-year-old woman. The teen, whose father died when he was 7 and whose mother had been living in another city since he was 8, had been diagnosed with uremia when he turned 15.

In 2013, Feng left his hometown in Southwest China's Guizhou province alone and ended up in Beijing, and was found by Lin Jia after he passed out on a street.

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 from where she was working in Zhejiang province.

On Dec 12, Feng underwent a kidney transplant, receiving a kidney from his mother.
