Согласно результатам существующих исследований, деструктивные процессы в коллагене характеризуются изменением длины, толщины волокон и их ориентацией в пространстве. Дезорганизация коллагена имеет ферментативные и не ферментативные механизмы. Цель исследования – исследование частоты и особенностей локализации бляшек Рэндалла и морфологическое исследование состояния соединительной ткани и базальной мембраны эпителия почечных канальцев разного уровня при мочекаменной болезни. Микроскопически исследованы препараты 29 биопсий почечной ткани, полученные от пациентов при фибро-уретеро-пиелоскопии (11), чрезкожной нефролитолапаксии (18) и препараты, полученные при 20 аутопсиях в случаях без видимой почечной патологии. Гистологические препараты окрашивались гематоксилином и эозином, для определения состояния волокон соединительной ткани методами Ван-Гизон, Маллори, Шифф-реактивом, альциановым синим, по Косу на кальцинаты. Результаты исследования показывают, что морфологические признаки мукоидного набухания соединительной ткани и базальной мембраны эпителия почечных канальцев разного уровня в сочетании с образованием микрокальцинатов требуют дальнейшего изучения возможной роли дезорганизации соединительной ткани почечной стромы в инициации камнеобразования в почках.                                                                                                             </p><p>                                                                                                                     </p></abstract><trans-abstract xml:lang="en"><p>According to a number of researchers, pathological changes in the structures of the renal papilla play a key role in the pathogenesis of urolithiasis. According to the results of existing studies, destructive processes in collagen are characterized by a change in the length, thickness of the fibers and their orientation in space. Collagen disorganization has enzymatic and non-enzymatic mechanisms. The aim of the study was to study the frequency and features of localization of Randall's plaques and morphological study of the state of connective tissue and the basement membrane of the epithelium of the renal tubules of different levels in urolithiasis. Microscopically studied preparations of 29 biopsies of renal tissue obtained from patients with fibro-uretero-pyeloscopy (11), percutaneous nephrolitholapaxy (18) and preparations obtained at 20 autopsies in cases without visible renal pathology. Histological preparations were stained with hematoxylin and eosin to determine the state of connective tissue fibers using Van Gieson, Mallory, Schiff-reagent, alcian blue, and Kos for calcifications. The results of the study show that the morphological signs of mucoid swelling of the connective tissue and basement membrane of the epithelium of the renal tubules of different levels in combination with the formation of microcalcifications require further study of the possible role of disorganization of the connective tissue of the renal stroma in the initiation of stone formation in the kidneys.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>патоморфология почки</kwd><kwd>мочекаменная болезнь</kwd><kwd>дезорганизация коллагена</kwd><kwd>бляшки Рэндалла</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pathology of the kidney</kwd><kwd>urolithiasis</kwd><kwd>disorganization of collagen</kwd><kwd>Randall's plaques</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pytel' AYa.
