Zheng Ren pointed at one of the arterial branches on the bladder. "Su Yun, mark this spot down," he said to the assistant, who was standing behind him.
Su Yun recorded the position of the spot that Zheng Ren had specified with a pen and paper.
He did not write it down in English or Chinese characters, opting instead for a sequence of unique symbols that only he could understand.
Even though his notes were simple, the A4-sized paper was almost completely filled and on the verge of being switched out.
He already had three full pages of notes.
"What is it? Any progress?" Su Yun had noticed slight changes in Zheng Ren's expression and suspected another new breakthrough.
"I think we can give it a try. It would be better to have a thinner guide wire. Given the surgical tools on hand, though, we may as well go with our original plan of using the neurological guide wire to dredge the thin arterioles," said Zheng Ren.
