Всем пациентам выполнены динамическое ТРУЗИ, динамическое ТПУЗИ и рентгенологическая дефекография (РД). Результаты УЗИ сопоставлены с данными РД.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: по данным РД, ВРИ была выявлена у 126/151 (83,4%) пациентов, по данным динамического ТРУЗИ — у 108/151 (71,5%), по данным динамического ТПУЗИ — у 110/151 (72,8%), по данным комплексного динамического УЗИ — у 124/151 (82,1%). Чувствительность, специфичность, положительная прогностическая ценность, отрицательная прогностическая ценность и общая точность динамического ТРУЗИ в диагностике ВРИ составили 82,5% (95% доверительный интервал (ДИ): 74,8–88,7), 84,0% (95% ДИ: 63,9–95,5), 96,3% (95% ДИ: 90,8–99,0), 48,8% (95% ДИ: 33,3–64,5) и 82,8% (95% ДИ: 75,8–88,4), соответственно, динамического ТПУЗИ — 81,7% (95% ДИ: 73,9–88,1), 72,0% (95% ДИ: 50,6–87,9), 93,6% (95% ДИ: 87,3–97,4), 43,9% (95% ДИ: 28,5–60,3) и 80,1% (95% ДИ: 72,9–86,2), комплексного динамического УЗИ — 92,1% (95% ДИ: 85,9–96,1), 68,0% (95% ДИ: 46,5–85,1), 93,6% (95% ДИ: 89,1–96,3), 63,0% (95% ДИ: 46,95–76,6) и 88,1% (95% ДИ: 81,8–92,8), статистически значимых различий выявлено не было.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: УЗИ — это безопасный высокочувствительный метод диагностики ВРИ у пациентов с синдромом обструктивной дефекации. Равнозначные показатели диагностической информативности динамического ТРУЗИ, динамического ТПУЗИ и комплексного динамического УЗИ позволяют использовать любую доступную методику для выявления ВРИ. Комплексное динамическое УЗИ представляется наиболее универсальным методом определения анатомо-функционального состояния прямой кишки.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: analysis of dynamic transrectal ultrasound (TRUS) and dynamic transperineal ultrasound (TPUS) accuracy in rectal intussusception (RI) diagnosis.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: a prospective cohort single-center diagnostic accuracy study of ultrasound for RI detection (January 2023 — October 2024) included 151 patients with obstructive defecation syndrome, without signs of complete rectal prolapse and without history of surgical treatment for pelvic floor descent syndrome. All patients underwent dynamic TRUS, dynamic TPUS and X-ray defecography. Ultrasound results were compared with X-ray defecography data.</p></sec><sec><title>RESULTS</title><p>RESULTS: according to the X-ray defecography, RI was detected in 126/151 (83.4%) patients, according to dynamic TRUS — in 108/151 (71.5%), according to dynamic TPUS — in 110/151 (72.8%), according to complex dynamic ultrasound — in 124/151 (82.1%). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of dynamic TRUS in RI detection were 82.5% (95% confidence interval (CI): 74.8–88.7), 84.0% (95% CI: 63.9–95.5), 96.3% (95% CI: 90.8–99.0), 48.8% (95% CI: 33.3–64.5) and 82.8% (95% CI: 75.8–88.4), respectively, dynamic TPUS — 81.7% (95% CI: 73.9–88.1), 72.0% (95% CI: 50.6–87.9), 93.6% (95% CI: 87.3–97.4), 43.9% (95% CI: 28.5–60.3) and 80.1% (95% CI: 72.9–86.2), complex dynamic US — 92.1% (95% CI: 85.9–96.1), 68.0% (95% CI: 46.5–85.1), 93.6% (95% CI: 89.1–96.3), 63.0% (95% CI: 46.95–76.6) and 88.1% (95% CI: 81.8–92.8), no statistically significant differences were found.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: ultrasound is a safe, highly sensitive method for RI detection in patients with obstructive defecation syndrome. Equivalent diagnostic accuracy of dynamic TRUS, dynamic TPUS and complex dynamic US allows using any available technique to detect RI. Complex dynamic US seems to be universal method for assessment the anatomical and functional state of rectum.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>внутренняя ректальная инвагинация</kwd><kwd>ультразвуковое исследование</kwd><kwd>рентгенологическая дефекография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rectal intussusception</kwd><kwd>ultrasound</kwd><kwd>defecography</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">Шелыгин Ю.А., Ачкасов С.И., Алешин Д.В., и соавт.
