However, optimal approaches to postoperative lithokinetic therapy in pediatric practice remain a subject of debate.</p> <p><bold>Objective:</bold> comparative analysis of the efficacy and safety profile of combined lithokinetic therapy, including alpha-1-adrenergic blockers and polychromatic polarized light, for improving the elimination of stone fragments after extracorporeal shock wave lithotripsy (ESWL) in children with urolithiasis.</p> <p><bold>Methods.</bold> This prospective randomized study included 250 children aged 2 to 18 years who underwent ESWL. All patients were randomized into three groups: a control group (n=150) receiving standard postoperative therapy, Group 2 (n=50) receiving a course of PPL exposure, and Group 3 (n=50) receiving a combination of alpha-1-adrenergic blockers (tamsulosin/silodosin) and a course of PPL exposure. To assess efficacy, the following parameters were analyzed: stone-free rate (SFR), time to stone expulsion, level of pain, and frequency of postoperative complications.</p> <p><bold>Results.</bold> Combined lithokinetic therapy resulted in the highest stone-free rate (88.0%), which was significantly higher than in the control group (60.0%; p&lt;0.001). The SFR in the PPL group was 76.0%. The dynamics of SFR achievement differed, occurring earlier in Groups 2 and 3. The lowest need for analgesia was noted in the combination therapy group (82.0% of patients required no pain relief). Dynamic ultrasound showed a significantly faster reduction in the size of residual fragments in the study groups. Postoperative complications were less frequent in Groups 2 and 3. No adverse effects from the use of alpha-1-adrenergic blockers were noted.</p> <p><bold>Conclusion.</bold> Combined lithokinetic therapy with alpha-1-adrenergic blockers and PPL may be associated with a higher rate of complete stone fragment passage after ESWL in children compared with standard therapy, as well as with a reduced need for analgesics.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Эффективная эвакуация фрагментов конкрементов является ключевым этапом, определяющим успех дистанционной ударно-волновой литотрипсии (ДУВЛ) у детей с уролитиазом. Однако оптимальные подходы к послеоперационной литокинетической терапии в педиатрической практике остаются предметом дискуссий.</p> <p><bold>Цель</bold>: сравнительный анализ эффективности и профиля безопасности применения комбинированной литокинетической терапии, включающей альфа-1-адреноблокаторы и полихроматический поляризованный свет для улучшения элиминации фрагментов конкрементов после ДУВЛ у детей с уролитиазом.</p> <p><bold>Методы. </bold>В рамках проспективного рандомизированного исследования было включено 250 детей от 2 до 18 лет, перенесших ДУВЛ. Все пациенты были рандомизированы на три группы: контрольная (n=150) - получала стандартную послеоперационную терапию, группа 2 (n=50) – курс воздействия ППС, группа 3 (n=50) – комбинацию альфа-1-адреноблокаторов (тамсулозин/силодозин) и курс воздействия ППС. Для оценки эффективности анализировались следующие показатели: stone free rate (SFR), время экспульсии конкрементов, уровень болевого синдрома и частота послеоперационных осложнений.</p> <p><bold>Результаты. </bold>Комбинированная литокинетическая терапия приводит к наибольшей частоте достижения статуса stone free – 88,0%, что достоверно выше, чем в контрольной группе (60,0%; p&lt;0,001). Показатель SFR в группе ППС составил 76,0%. Динамика достижения SFR была различной (более ранней в группах 2 и 3). Наименьшая потребность в анальгезии отмечена в группе комбинированной терапии (82,0% пациентов не требовали обезболивания). Динамическое УЗИ показало достоверно более быстрое уменьшение размеров остаточных фрагментов в исследуемых группах. Послеоперационные осложнения встречались реже в группах 2 и 3. Побочных действий от применения альфа-1-адреноблокаторов не отмечалось.</p> <p><bold>Заключение. </bold>Комбинированная литокинетическая терапия альфа-1-адреноблокаторами и ППС может ассоциироваться с более высокой частотой полного отхождения фрагментов конкрементов после ДУВЛ у детей по сравнению со стандартной терапией, а также со снижением потребности в анальгетиках.</p></trans-abstract><kwd-group xml:lang="en"><kwd>children, urolithiasis, extracorporeal shock wave lithotripsy, lithokinetic therapy, alpha-1-adrenergic blockers, polarized light</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дети, мочекаменная болезнь, дистанционная ударно-волновая литотрипсия, литокинетическая терапия, альфа-1-адреноблокаторы, поляризованный свет</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
