Hurry up, give me a cup! Dr. Zhang Hong of JNU's First Affiliated Hospital said on a flight from Guangzhou to New York. Then he sucked mouthfuls of urine through a tube from an elderly airline passenger who lay on the floor.
 

According to the flight information, China Southern flight 399 left Guangzhou at 1:55 a.m. on Nov. 19. Most of the passengers fell asleep after midnight. 
 

(On the plane)
Six hours before the scheduled landing time, the purser in the rear cabin announced that an elderly man was in desperate need of medical assistance for his inability to urinate. Dr. Zhang from the First Affiliated Hospital of Jinan University (also known as the Guangzhou Overseas Chinese Hospital) and Dr. Xiao Zhanxiang from Hainan General Hospital immediately rose to examine the man. They found that he risked bladder rupture if roughly 1000 milliliters of urine was not rapidly removed from his bladder. Because of the plane's limited medical equipment, Dr. Zhang had to suck out the urine, spitting it into the cup for 37 minutes. He successfully removed 700 to 800 milliliters.

Asked later how he knew what to do in such an emergency, Dr. Zhang calmly replied that he couldn't come up with a better way at the time and wanted only one thing: to relieve the man's pain, his duty as a doctor.
