Beijing | Chinese doctors have removed an incredible 420 stones from the kidney of a 55-year-old gypsum tofu lover. The emergency surgery that lasted nearly two hours was performed on the left kidney of He Dong at Dongyang People’s Hospital in Jinhua city of East China’s Zhejiang province after a CT scan for abdominal pain showed his kidney filled with stones.
Dong told doctors that he ate a large daily diet of gypsum tofu, a local food with a high concentration of calcium sulfate. Soy products, especially gypsum tofu, are very high in calcium, the excess of which cannot be excreted from body without a sufficient intake of water, said the doctor Wei Yubin.
The operation almost took two hours. We spent 45 minutes just taking out the tiny stones. After the operation, my hands and legs were both numb, Yubin said.
The doctors removed the 420 stones one at a time with forceps, the Mirror reported. Dang said he didn’t like drinking water but has been ordered to change his eating habits. The doctors have advised Dang to cut down on the daily consumption of tofu as he kept the stones as a souvenir.
