Проспективно проанализированы данные 51 КТУ и 34 МРУ, полученных у пациентов с травмами верхних мочевых путей. Исследования выполнялись на 160-срезовом сканере Aquilion Prime (Toshiba, Япония) и высокопольных аппаратах с напряженностью магнитного поля 1,5 Тл Vantage Atlas (Toshiba, Япония) и 3,0 Тл Ingenia (Philips, Нидерланды). В 92,2% случаев была также проведена экскреторная урография, в 74,5% – ультразвуковое исследование. Оценивались уровень обструкции, ее причины, состояние окружающих структур, наличие осложнений.</p></sec><sec><title>Результаты</title><p>Результаты. Уровень стриктуры мочеточника был верно определен во всех исследованиях при КТУ, наиболее часто (68,6% случаев) вовлекалась нижняя треть органа. По данным МРУ травматические стриктуры идентифицированы в 94,0% случаев. МР-исследование позволило ограничиться нативными сериями у 51,0% пациентов, КТ – у 27,5%. МРУ чаще выявляла сопутствующие травме изменения: неравномерное утолщение стенки мочеточника было отмечено в 44,1% (при КТУ – в 27,5%), инфильтрация периуретральной клетчатки – в 43,1% (при КТУ – в 37,2%), скопление жидкости в малом тазу – в 9,8% (при КТУ – в 7,8%) случаев. Методики также позволяли установить наличие свищевых ходов: МРУ была полезна в предоперационной визуализации патологических соустьев в 100% случаев. КТУ смогла продемонстрировать подтекание контрастного вещества и/или затекание его во влагалище в 66,7% случаев.</p></sec><sec><title>Заключение</title><p>Заключение. МРУ демонстрирует сопоставимую с КТУ чувствительность в выявлении травм мочеточников (в том числе в диагностике таких осложнений, как свищи) и может применяться у пациентов с противопоказаниями к КТУ, а также, благодаря отсутствию ионизирующего излучения, – для исследований в динамике.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To assess the sensitivity of computed tomography urography (CTU) and magnetic resonance urography (MRU) (native versus contrast-enhanced studies) in patients with traumatic ureteral strictures.</p></sec><sec><title>Material and methods</title><p>Material and methods. The data of 51 CTUs and 34 MRUs made in patients with upper urinary tract injuries were prospectively analyzed. The studies were performed using an Aquilion Prime 160-slice scanner (Toshiba, Japan) and high-field devices at a magnetic field strength of 1.5 Tesla Vantage Atlas (Toshiba, Japan) and at 3.0 Tesla Ingenia (Philips, Netherlands). Excretory urography was also carried out in 92.2% of cases; ultrasound examination was made in 74.5%. The degree of obstruction, its causes, the state of the adjacent structures, and the presence of complications were assessed.</p></sec><sec><title>Results</title><p>Results. All (100%) CTU studies correctly estimated the level of stricture of the ureter; the lower third of the organ was involved most frequently (68.6%). MRU identified traumatic strictures in 94.0% of cases. MRU and CTU could be confined to native series in 51.0 and 27.5% of patients, respectively. MRU more commonly revealed the changes concurrent with injuries: there was diffuse ureter wall thickening in 44.1% (27.5% at for CTU), periureteral fat infiltration in 43.1% (37.2% at CTU), and pelvic fluid accumulation in 9.8% (7.8% at with CTU). The techniques could also establish the presence of sinus tracts: MRU was useful in the preoperative imaging of pathological fistulas in 100%. CTU was able to demonstrate the leakage of a contrast agent and/or its flow into the vagina in 66.7%.</p></sec><sec><title>Conclusion</title><p>Conclusion. MRU demonstrates the sensitivity comparable to that of CTU in detecting ureteral injuries (including in diagnosing complications, such as fistulas) and can be used in patients with contraindications to CTU and, due to the absence of ionizing radiation, for follow-up studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>cтриктура мочеточника</kwd><kwd>урообструкция</kwd><kwd>компьютерная урография</kwd><kwd>магнитнорезонансная урография</kwd><kwd>гидронефроз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ureteral stricture</kwd><kwd>uroobstruction</kwd><kwd>computed tomography urography</kwd><kwd>magnetic resonance urography</kwd><kwd>hydronephrosis</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование не имело спонсорской поддержки.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study had no sponsorship.</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">Громов А.И., Буйлов В.М.
