From a practical point of view, it seems very dangerous to have a disease of an organ in the absence of a paired one, since in this case, compensation for the defect cannot occur.</p></abstract><trans-abstract xml:lang="ru"><p>Односторонняя недостаточность или совершенное отсутствіе почки, встрѣчающіяся въ первомъ случаѣ какъ пріобрѣтенный дефектъ, во второмъ—какъ врожденный порокъ, имѣютъ существенное клиническое, практическое значеніе. Съ практической точки зрѣнія представляется очень опаснымъ заболѣваніе органа при отсутствіи парного ему, такъ какъ въ этомъ случаѣ не можетъ наступить компенсація дефекта.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Kazan Medical archive</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Казанский медицинский архив</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list/></back></article>
