420 stones found in man's kidney

Around 420 stones have been taken out from a patient's kidney in Dongyang city, Zhejiang province.

The man surnamed He, 55, does not like drinking water, and is really fond of bean curd.

He ate it almost everyday, which may have caused the kidney stones, China News Service reported.

"I have never seen so many stones", said a doctor who has been practicing medicine for eight years.
