Thursday night, doctors, researchers and patients celebrated a huge accomplishment for Barnes-Jewish Hospital and Washington University.

The staff celebrated their 1,500 adult lung transplant. A grandmother named Tracy Conway was the patient. She credits the program for keeping her alive.

Conway was diagnosed with Chronic Obstructive Pulmonary Disease. She prayed she would live to see her grandkids grow up as she waited for a lung transplant. She got two new lungs last month. Barnes-Jewish Hospital and Washington University's Lung Transplant Program is the 8th largest in the world and one of the oldest lung transplant programs in the country.

There are only three other hospitals in the country that have performed at least 1,500 lung transplants. Doctors say more organ donations are critically needed worldwide. They strongly encourage people to consider becoming an organ donor to help save lives.
