В литературе продолжается процесс обсуждения необходимости систематизации терминов, используемых при описании положения неопущенного яичка. Из-за путаницы в терминологии возникает сложность в обобщении и анализе полученных данных. Одно и тоже положение неопущенной гонады разными авторами описывается по-разному, что привело к появлению в начале XXI века множества авторских классификаций крипторхизма. Данный обзор литературы констатирует тот факт, что с течением времени так и не найден консенсус в части классификации неопущенных яичек. В настоящее время существует необходимость в обобщении имеющихся данных для выбора оптимального алгоритма лечения. Если алгоритм лечения пальпируемых яичек хорошо изучен, то при выборе метода лечения непальпируемых форм крипторхизма в хирургическом сообществе сохраняются дискуссии.</p></abstract><trans-abstract xml:lang="en"><p>The analysis of literature data (PubMed database, Google Scholar) is presented, devoted to the problematic study of the cryptorchidism's terminology and classification. The literature periodically calls for systematization terms used in describing the position undescended testis. Due to the confusion in terminology, it is difficult to generalize and analyze the data obtained. The same position of the undescended testis is described differently by various authors, which led to the appearance of many authors' cryptorchidism classifications at the beginning of the 21st century. This review of the literature states the fact that, over time, no consensus has been found regarding the classification of undescended testicles. Currently, there is a need to generalize the available data to select the optimal treatment algorithm. If the treatment algorithm for the palpable testicles is well studied, then the choice of a treatment method for the cryptorchidism non-palpable forms remains debated in the surgical community.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крипторхизм</kwd><kwd>классификация крипторхизма</kwd><kwd>терминология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cryptorchidism</kwd><kwd>classification</kwd><kwd>terminology</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">Ерохин А.П., Воложин С.И., Крипторхизм.
