По рекомендациям ЕАУ от 2022 г., РИРХ является одним из основных методов хирургического лечения конкрементов почек размерами 10–20 мм. Наиболее эффективным и безопасным для дезинтеграции конкрементов является гольмиевый лазер, который позволяет достичь таких эффектов как фрагментация и разрушение конкрементов в пыль.</p></sec><sec><title>Цель</title><p>Цель: Определить хирургические возможности гольмиевой лазерной литотрипсии при единичном и множественном одностороннем нефролитиазе с помощью одноразовых гибких уретерореноскопов.</p></sec><sec><title>Материал и методы</title><p>Материал и методы: С октября 2021 по октябрь 2022 г. нами выполнены 124 операции с использованием гибкого уретерореноскопа LithoVue у пациентов с нефролитиазом – 70 мужчин и 54 женщины, средний возраст больных составил 54 (27–74) года. Пациенты были разделены на 2 группы: группа I (56 пациентов) с единичным конкрементом почки, группа II (68 пациентов) с множественными конкрементами в количестве от 2 до 7 шт. Размеры конкрементов варьировались от 5 до 20 мм, а их плотность по компьютерной томографии (КТ) составила 214–1620 HU. Во время работы гольмиевого лазера Auriga XL в режиме дробления использовались многоразовые лазерные фиброволокна LightTrail 230 µm, выставлены следующие настройки лазера: частота – 8 Гц, энергия импульса – 1200 мДж и LightTrail 270 µm, выставлены следующие настройки лазера: частота – 12 Гц, энергия импульса – 1800 мДж. Данные настройки являются максимальными для представленных лазерных волокон.</p></sec><sec><title>Результаты</title><p>Результаты: Среднее время дезинтеграции 1-го конкремента (V = 1 см3) – 28,3 мин. Время дезинтеграции конкрементов в группе I – 21,4 ± 6,7 мин. Время дезинтеграции конкрементов в группе II – 42,3 ± 9,4 мин. Время операции для группы I – 27,4 ± 8,3 мин, для группы II – 54,6 ± 12,4 мин. Пребывание пациентов в стационаре для I и II группы составило 2,5 ± 1 и 3 ± 1 койко-дней. Уровень отсутствия камней по КТ в группе I составил 92,6%, в группе II – 88,2%. В группе I – 2 пациентам и в группе II – 5 пациентам потребовалась повторная РИРХ. В группе I у 1 пациента (1,8%) и в группе II у 3 (4,4%) развились осложнения II класса по Clavien-Dindo (острый пиелонефрит). У остальных пациентов осложнения не превышали I класс по Clavien-Dindo. Нарушений в работе используемого оборудования во время операции отмечено не было.</p></sec><sec><title>Заключение</title><p>Заключение: РИРХ – это безопасный и эффективный метод, имеющий низкий уровень осложнений, быстрое послеоперационное восстановление и короткое время пребывания в стационаре, может использоваться в качестве основного метода дезинтеграции конкрементов почек размерами до 20 мм.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction: Retrograde intrarenal surgery (RIRS) alongside percutaneous surgery is gaining a leading position in the nephrolithiasis treatment. According to 2022 EAU Guidelines, RIRS is one of the basic surgical modalities to treat 10-20 mm kidney concrements. Turning concrements into dust, holmium laser is the most effective and safest method for concrement disintegration.</p></sec><sec><title>Objective</title><p>Objective: To determine surgical possibilities of holmium laser lithotripsy for single and multiple unilateral nephrolithiasis using disposable flexible ureterorenoscopes.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: We performed 124 interventions from October 2021 to October 2022 using LithoVue flexible ureterorenoscope in patients with nephrolithiasis, of them 70 males and 54 females with the mean age being 54 (27–74) years. Patients were divided into 2 groups: group I (56 patients) with a single renal concrement, group II (68 patients) with multiple concrements (2 to 7 pieces). The concrement size ranged from 5 to 20 mm. The density of kidney concrements on computed tomography (CT) was 214 to 1,620 HU. LightTrail 230 μm and 270 μm reusable laser fibers were chosen for Auriga XL holmium laser crushing mode. Laser operating settings were as follows: frequency 8 Hz, pulse energy 1,200 mJ (LightTrail 230 µm) and frequency 12 Hz, pulse energy 1,800 mJ (LightTrail 270 µm). These are the maximum setting values for the specific laser fibers.</p></sec><sec><title>Results</title><p>Results: Average time of 1 concrement disintegration (V = 1 cm3) was 28.3 minutes. Concrement disintegration time was 21.4 ± 6.7 minutes (group I) and 42.3 ± 9.4 minutes (group II). Intervention time was 27.4 ± 8.3 minutes (group I) and 54.6 ± 12.4 minutes (group II). In-hospital stay was 2.5 ± 1 days (group I) and 3 ± 1 days (group II). The rate of surgical success according to CT scans was 92.6% (group I) and 88.2% (group II). Two patients in group I and 5 patients in group II required reintervention. One patient (1.8%) in group I and 3 patients (4.4%) in group II developed an acute pyelonephritis (Clavien-Dindo classification, grade II). In the remaining patients the complications did not exceed Clavien-Dindo grade I. There were no equipment-related issues in the perioperative period.</p></sec><sec><title>Conclusions</title><p>Conclusions: As a safe and effective procedure with low complication rate, fast postoperative recovery, and short hospital stay, RIRS can be used as a method of choice for disintegration of kidney concrements up to 20 mm in size.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ретроградная интраренальная хирургия</kwd><kwd>конкремент</kwd><kwd>гольмиевый лазер</kwd><kwd>уретерореноскоп</kwd><kwd>лазерные фиброволокна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>retrograde intrarenal surgery</kwd><kwd>concrement</kwd><kwd>holmium laser</kwd><kwd>ureterorenoscope</kwd><kwd>laser fibers</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">Мартов А.Г., Ергаков Д.В., Гусейнов М.А. и др.
