ABSTRACT: 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.
