[Peculiarities morphology and structure of the uroliths].

THE AIM: According to statistical data of a number of the countries, have an urolithic disease from 5% to 15% of the population today. A recurrence arises at 50-85% of patients. The purpose of this work was complex studying of morphology, structure, mineral structure of urolit, identification of regularities of their formation, establishment of interrelation between mineral and organic matter in structure of urolit. MATERIALS: the urinary stones from the urology departments of hospitals and clinics of the Tomsk region (Russia). METHOD: s: crystallomorphological (the study of the surface morphology of uroliths binocular and trinocular microscopes); polarizing optical (study of the mineral composition of uroliths on a polarizing microscope); x-ray crystallography (the study of spectral composition on the apparatus DRON-3); electron microscopic (study of the peculiarities of morphology of crystals in an electron microscope). RESULTS: On features of morphology of a surface four types of urolit are allocated: druzovidny, sferolitovy, combined, korallovidny. Structural kinds of urolit: crystal and granular, dendritovidny, combined, rhythmic - zone. In structure of urolit the following types of rhythms are established: zone, granular, combined. In the urolitakh with rhythmic - the zone structure allocated elements of their building: kernel, layer, zone, rhythm. A mineral part of uric stones is presented by the crystals belonging to the classes: oxalates, phosphates, urat . SUMMARY: The peculiarities of the morphology of the selected four types of uroliths: druzoid, with, combined, coral. Structural variations uroliths: crystal-grained Shelly, dendritic, combined, rhythmically zoned. In the structure of uroliths, the following types of rhythms: zoned, granular, combined. In urolith with rhythmically zoned structure selected elements of their structure: core, layer, area, rhythm. DISCUSSION: Morphological and structural features of the structure of urolites, especially the presence of rhythmic zoning, due to the alternation of layers of mineral and organic matter, indicate a close relationship between the living organism and the organo-mineral aggregate in the human urinary system. With a high degree of confidence we can talk about the symbiosis of living and mineral matter in the human body; as a result of this symbiosis, organic-mineral formations are formed, which are often the further cause of some diseases (for example, urolithiasis and cholelithiasis). CONCLUSION: The complex research of uric stones allows to obtain important information on their structure, structure and features of morphology. Morphological and structural features of the structure of urolit, in particular existence of the rhythmic zonality caused by alternation of layers of mineral and organic matter demonstrate close interrelation between a live organism and the organo-mineral unit in an urinary system of the person.

[The study of mineral composition and structure of uroliths in the residents of Tomsk district (Tomsk)].

AIM: To successfully treat and prevent urolithiasis, the composition and structure of uroliths should be examined using modern analytical techniques. For a long time, studies of the biomineral formation in the human body have been conducted exclusively in the field of medicine. The main attention has been paid to the diagnosis and treatment of diseases leading to the occurrence of pathogenic formations. At the same time, it is quite obvious that it is important to have a clear idea about the causes of pathogenic formations, the mechanisms for their further formation, composition and structure. Currently, these issues are widely studied all over the world by mineralogists, biochemists, geo-ecologists using methods of mineralogical analysis. The aim of this work was to determine the content of the elements that make up uroliths. This value should be normalized by the clarks of the noosphere. Studies on the mineral composition and structure of uroliths in the Tomsk region allowed to calculate the content of elements. It turned out that each medical district has its own specific geochemical series, which depends, probably, on natural and technogenic factors. MATERIALS AND METHODS: The study included urolith samples obtained from residents of 4 medical sub-districts of Tomsk district. 100 samples of different mineral composition were studied. Analytical techniques including crystal-morphological, spectral, X-ray structural, instrumental neutron-activation, electron microscopic analyses were used to investigate the morphology, mineral composition and structure of uroliths. RESULTS: The average content of elements in the uroliths, and the element concentrations normalized by the clark were established. After calculating the concentration, geochemical associative series of elements were formed. Depending on the morphology, drusiform, microspherolite, porous, coral formations, uroliths with a smoothed surface and stones with combined morphology were identified. Three groups of uroliths were defined according to their structural features: crystalline-granular, spherolithic and combined. CONCLUSION: Studies to determine the mineral composition and structure of the uroliths of the inhabitants of the Tomsk region made it possible to calculate the content of the elements that make up uroliths, normalized by clarks of the noosphere. Each medical sub-district has its own specific geochemical series, which depends on natural and technogenic factors. The increased value of the indicator of the content of elements in uroliths should serve as a warning factor for developing measures to reduce the urolithiasis incidence in the population.

[The list of literature (review) on studying urinary stones by russian researchers (Dated between 1965 and 2015, in 2 parts) Part I].

Urolithiasis is one of the most common urological diseases. Determination of mineral composition and structure of urinary stones is necessary for urologists to provide targeted therapeutic and preventive measures. Existing global standards for management of kidney stones require analysis of stone composition to be done for each urolithiasis patient. The list of literature representing the scientific work of the Russian scientists on studying the mineral composition and structure of urinary stones, includes articles, abstracts, monographs, dissertations presented as reports and presentations at conferences and seminars (mineralogical and urological). Over half a century (1965-2015) there were 178 articles published in geological and urological journals, 7 published monographs and 8 defended dissertations (2 on Medical Sciences and 6 on Geological and Mineralogical Sciences).

Research on urinary stones involves urologists, crystallographers, mineralogists. A considerable amount of literature has been published as articles, abstracts of articles presented at conferences and seminars (mineralogical and urological), and monographs, dissertations. The authors of the scientific review prepared the list of the literature, reflecting the scientific activities of Russian scientists in studying the mineral composition and structure of urinary stones for half a century (1965-2015). The list is presented in two parts. The information provided in the 2nd part (2002-2015), is an update of the scientific review on studying urinary stones (Part I, 1965-2001).
