Of the nine defendants, five were prosecuted as main culprits and four others, including two nurses, a surgical assistant and an anesthesiologist, were tried as accessories, the court said.
The court added that the nine defendants had paid compensation worth more than 1.47 million yuan to Wang. The compensation and forgiveness from the teenager and his family led to leniency in sentencing.
Human organ trade and organ donations from living donors, except for close family members such as spouses and blood relatives, are illegal in China. An underground trade in human organs is booming in the country where there is a huge demand for transplants.
Ministry of Health statistics show that about 1.5 million people in China need transplants, but only 10,000 operations are performed each year.
Medical experts have long urged the establishment of a transparent system for organ donation and distribution in order to boost the number of donors.
"China should not only crackdown on the underground organ trade but also speed up in establishing a scientific and comprehensive system for organ transplants and donations," said Xia Xueluan, a sociology professor at Peking University.
Vice Health Minister Huang Jiefu has said China is considering an organ transplant system that incorporates measures, including offering donors compensation, to encourage donations.
