Kidney stone consists of various organic, inorganic and semi organic compounds. Mineral oxalate monohydrate and di-hydrate are the main inorganic constituents of kidney stones. However, mechanisms leading to the formation of mineral oxalate kidney stones are not clearly understood. In this field of study, there are several hypotheses including nucleation, crystal growth and/or aggregation of formation of AOMH (Ammonium oxalate monohydrate) and AODH (Ammonium oxalate di-hydrate) crystals. The effect of some urinary species such as ammonium oxalate, calcium citrate, proteins and trace elements were reported by the author. The kidney stone constituents are grown in silica gel medium (SMS) which provides the necessary growth simulation (in-vivo). In the artificial urinary stone growth process, identification of growth parameters within the different chemical environment was carried out and reported for the urinary crystals such as CHP, SHP, BHP and MHP. In the present study, SrCrMHP (Strontium chromium magnesium hydrogen phosphate) crystals are grown in three different growth faces to attain the total nucleation reduction. Extension of this research, many characterization studies have been carried out and the results are reported.
