[Size and formation of crystals in urinary calculi studied with x-ray diffraction profiles].
Application on in vivo grown urinary calculi shows that crystals of uric.acid.dihydrate and calcium.oxalate.dihydrate are larger than crystals of uric.acid.siccum and calcium.oxalate.monohydrate. These findings could be explained by the hypothesis, that dehydrated forms are secondary formations out of dihydrate crystals.
