Патологический кристаллогенез рассматривается как следствие превышение порога растворимости ряда минеральных компонентов мочи, с одной стороны, и как следствие посттрансляционных дефектов основного протеома мочеобразования – уромодулина (UMOD), демонстрирующего у здоровых саногенетическую систему обеспечения стабильности биофизического гомеостаза: коллоидных свойств мочи. Однако, кроме этого, UMOD, связывая маннозо-зависимые пили инфекционных агентов, блокирует контакт бактерий с уротелиоцитами, притом что инфицирование мочевого тракта является известным фактором уролитиаза. Путем моделирования мочи у здоровых лиц соинкубацией с бактериями Е.сoli  продемонстрировано снижение концентрации полимеризованного уромодулина в моче, как  фактор увеличения риска образования кристаллов оксалата кальция. </p></abstract><trans-abstract xml:lang="en"><p>The pathogenetic approach to the metaphylaxis of urolithiasis is universally a socially significant health problem due to the increase in morbidity and, especially, its recurrent course, despite the achievements of pharmacotherapy and the use of lithotripsy. Pathological crystallogenesis is considered as a consequence of exceeding the solubility threshold of a number of mineral components of urine, on the one hand, and as a consequence of posttranslational defects of the main proteome of urination - uromodulin (UMOD), demonstrating in healthy people a sanogenetic system for ensuring the stability of biophysical homeostasis: colloidal properties of urine. However, in addition, UMOD, by binding mannose-dependent pills of infectious agents, blocks the contact of bacteria with urotheliocytes, despite the fact that infection of the urinary tract is a known factor of urolithiasis. By modeling the urine of healthy individuals by coincubation with E. coli bacteria, a decrease in the concentration of polymerized uromodulin in urine was demonstrated as a factor in increasing the risk of formation of calcium oxalate crystals</p></trans-abstract><kwd-group xml:lang="ru"><kwd>уролитиаз</kwd><kwd>биокристалломика</kwd><kwd>протеом</kwd><kwd>уромодулин</kwd><kwd>биофизический гомеостаз</kwd><kwd>коллоидные свойства мочи</kwd><kwd>Е. сoli</kwd><kwd>оксалат кальция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>urolithiasis</kwd><kwd>biocrystallomics</kwd><kwd>proteome</kwd><kwd>uromodulin</kwd><kwd>biophysical homeostasis</kwd><kwd>urine colloidal properties</kwd><kwd>Е. сoli</kwd><kwd>calcium oxalate</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках государственного задания по теме: «Изучение молекулярных и клеточных компонентов патогенеза социальнозначимых заболеваний для разработки методов ранней диагностики и лечения.» (регистрационный номер №121060200125-2).</funding-statement><funding-statement xml:lang="en">supported by the Ministry of Science and Higher Education of the Russian Federation (Project No. № 121060200127-6).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pak CY.
