GUANGZHOU:Parents and doctors suspect milk powder could be the cause of a kidney stone in an 8-month-old girl in Guangzhou, local media reported yesterday.

The child, diagnosed with a stone in her left kidney by doctors at Guangzhou No 8 People's Hospital last week, is said to have taken Dumex milk formula since birth, the Guangzhou-based New Express Daily said.

She reportedly did not suffer from any kidney ailment when her mother first took her for a medical checkup in Hubei province last September following the melamine-contaminated milk scare in the country.
