On a red-eye flight Tuesday from Guangzhou to New York, a doctor came to the aid of an elderly Chinese man who was unable to relieve himself and at risk of a ruptured bladder.
Six hours before the plane was due to land, Zhang Hong and Xiao Zhanxiang, both vascular surgeons at hospitals in China, had to think on their feet when a fellow passenger found himself unable to empty his very full bladder.
Zhang and Xiao determined that the man was holding in about 1 liter of urine — more than twice the normal daytime capacity — that needed to be drained immediately.
