Мочекаменная болезнь (МКБ) представляет собой значительную урологическую проблему, затрагивающую 10 – 15% населения и характеризующуюся высокой частотой рецидивов — 30 – 50%. Трансуретральная нефролитотрипсия (ТНЛ) является одним из современных подходов к лечению камней размером до 2 см. Внедрение аспирационных мочеточниковых кожухов обеспечивает вакуумную аспирацию, что позволяет эффективно удалять мелкие фрагменты конкрементов и улучшать результаты лечения, снижая как время операции, так и риск инфекционных осложнений.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Провести анализ клинической эффективности и безопасности использования аспирационных кожухов в процессе ТНЛ по сравнению со стандартными кожухами.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено проспективное рандомизированное исследование с включением 32 пациентов с нефролитиазом, случайным образом распределённых на две группы по 16 пациентов. В группе 1 выполняли ТНЛ с использованием аспирационного кожуха 12 / 14Fr (ClearPetra), в группе 2 — ТНЛ с использованием мочеточникового кожуха Navigator HD 12 / 14 Fr (Boston Scientific). Были собраны и проанализированы демографические данные пациентов, характеристики конкрементов, интра- ипослеоперационные результаты.</p></sec><sec><title>Результаты</title><p>Результаты. В группе 1 время оперативного вмешательства и литотрипсии было короче. SFR составил 93,75% в группе 1 и 81,25% — в группе 2. Увеличение лейкоцитов и СРБ менее значительно в группе 1 (9 ± 1,306 и 5,5 ± 1,074 соответственно) в сравнении с группой 2 — (10,350 ± 2,263 и 7,9 ± 2,058). Время пребывания в стационаре также было короче в группе 1 (2,0 ± 0,5 дня) по сравнению с группой 2 (4,0 ± 0,602 дня).</p></sec><sec><title>Заключение</title><p>Заключение. Применение аспирационного мочеточникового кожуха при ТНЛ является безопасным и эффективным методом лечения конкрементов почек размером до 2 см. Использование аспирационных кожухов улучшает показатели SFR, снижает риск инфекционных осложнений в послеоперационном периоде и сокращает время госпитализации по сравнению с использованием стандартных мочеточниковых кожухов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Urolithiasis represents a major urological challenge, affecting 10 – 15% of the population with recurrence rates of 30 – 50%. Transurethral nephrolithotripsy (TUNL) is a contemporary approach for stones ≤ 2 cm. The adoption of aspiration ureteral access sheaths enables vacuum-assisted fragment evacuation, enhancing treatment outcomes by reducing operative time and minimising infectious complications.</p></sec><sec><title>Objective</title><p>Objective. To evaluate the clinical efficacy and safety of aspiration sheaths during TUNL compared with standard sheaths.</p></sec><sec><title>Materials &amp; methods</title><p>Materials &amp; methods. This prospective randomised study enrolled 32 patients with nephrolithiasis, randomised 1:1 to two groups (n = 16 each). Group 1 underwent TUNL using a 12/14 Fr aspiration sheath (ClearPetra®); group 2 received a standard 12/14 Fr ureteral access sheath (Navigator™ HD, Boston Scientific). Patient demographics, stone characteristics, and intra-/postoperative outcomes were prospectively collected and analysed.</p></sec><sec><title>Results</title><p>Results. Operative and lithotripsy times were shorter in group 1. Stone-free rate (SFR) was 93.8% (group 1) versus 81.3% (group 2). Postoperative leucocytosis and C-reactive protein rises were less pronounced in group 1 (9 ± 1.3 and 5.5 ± 1.1, respectively) than group 2 (10.4 ± 2.3 and 7.9 ± 2.1). Hospital stay was shorter in group 1 (2.0 ± 0.5 days) versus group 2 (4.0 ± 0.6 days).</p></sec><sec><title>Conclusion</title><p>Conclusion. Aspiration ureteral access sheaths during TUNL offer a safe, efficacious option for renal stones ≤ 2 cm, yielding superior SFR, reduced infectious risk, and shorter hospitalisation compared with standard sheaths.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аспирационный кожух</kwd><kwd>мочеточниковый кожух</kwd><kwd>трансуретральная нефролитотрипсия</kwd><kwd>мочекаменная болезнь</kwd><kwd>камни почек</kwd></kwd-group><kwd-group xml:lang="en"><kwd>suction sheath</kwd><kwd>ureteral access sheath</kwd><kwd>transurethral nephrolithotripsy</kwd><kwd>urolithiasis</kwd><kwd>kidney stone</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки.</funding-statement><funding-statement xml:lang="en">The study was not sponsored.</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">Sorokin I, Mamoulakis C, Miyazawa K, Rodgers A, Talati J, Lotan Y.
