Title: Solubility data of compounds relevant to human health. Solubility of substances related to urolithiasis

Series: Solubility Data Series; editor-in-chief: Mark Salomon

Task Group
E. Königsberger and L.-C. Königsberger

The prevention and treatment of crystal deposition in the human body are based on the understanding of the physico-chemical properties underlying the precipitation of the substances involved. Amongst these properties, the solubilities of the crystals are very important. In the scope of urolithiasis, there are more than 20 different types of kidney stones composed of calcium oxalate hydrates (mono-, di- and trihydrate), ammonium magnesium phosphate (struvite), calcium phosphates (hydroxyapatite and brushite), uric acid and urates, cystine and xanthine. Solubilities of these substances can be incorporated in databases of sophisticated software packages that permit solubility calculations in artificial urine solutions. The results of these simulations would lead to some understanding and/or useful suggestions regarding the cause, prevention and treatment of renal or bladder calculi. Nevertheless, proper modelling of the solubilities of these substances requires reliable solubility constants. Thus it is necessary to critically assess the literature values reported for these substances. Recently, two reviews on this subject have been published:
