However, optimal approaches to postoperative lithokinetic therapy in pediatric practice remain a subject of debate.</p> <p><bold>AIM: </bold>To perform a comparative analysis of the efficacy and safety profile of the combined lithokinetic therapy, including alpha-1-adrenergic blockers and polychromatic polarized light, for improving the elimination of stone fragments after extracorporeal shock wave lithotripsy in children with urolithiasis.</p> <p><bold>METHODS: </bold>This prospective randomized study included 250 children aged 2 to 18 years who underwent extracorporeal shock wave lithotripsy. All patients were randomized into three groups: a control group (<italic>n</italic>=150) receiving standard postoperative therapy, Group 2 (<italic>n</italic>=50) receiving a course of polychromatic polarized light exposure, and Group 3 (<italic>n</italic>=50) receiving a combination of alpha-1-adrenergic blockers (tamsulosin/silodosin) and a course of polychromatic polarized light exposure. To assess efficacy, the following parameters were analyzed: stone-free rate (SFR) criteria, time to stone expulsion, level of pain, and frequency of postoperative complications.</p> <p><bold>RESULTS: </bold>The combined lithokinetic therapy has resulted in the highest stone-free rate (88.0%), which was significantly higher than in the control group (60.0%; <italic>p</italic> &lt;0.001). SFR criteria in the polychromatic polarized light group was 76.0%. Dynamics of SFR criteria differed; it was 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 size reduction of residual fragments in the study groups. Postoperative complications were less frequent in Groups 2 and 3. No adverse effects of alpha-1-adrenergic blockers were noted.</p> <p><bold>CONCLUSION:</bold> The combined lithokinetic therapy with alpha-1-adrenergic blockers and polychromatic polarized lightis is associated with a higher rate of complete stone fragment passage after extracorporeal shock wave lithotripsy in children compared to standard therapy; it also reduces the need for analgesics.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Эффективная эвакуация фрагментов конкрементов является ключевым этапом, определяющим успех дистанционной ударно-волновой литотрипсии у детей с уролитиазом, однако оптимальные подходы к послеоперационной литокинетической терапии в педиатрической практике остаются предметом дискуссий.</p> <p><bold>Цель исследования </bold>― сравнительный анализ эффективности и профиля безопасности применения комбинированной литокинетической терапии, включающей α1-адреноблокаторы и полихроматический поляризованный свет для улучшения элиминации фрагментов конкрементов после дистанционной ударно-волновой литотрипсии у детей с уролитиазом.</p> <p><bold>Методы. </bold>Участники проспективного исследования в возрасте от 2 до 18 лет, перенёсшие дистанционную ударно-волновую литотрипсию (<italic>n</italic>=250), рандомизированы на три группы: пациенты группы 1 (<italic>n</italic>=150; контрольная) получали стандартную послеоперационную терапию, в группе 2 (<italic>n</italic>=50) ― курс воздействия поляризованным светом, в группе 3 (<italic>n</italic>=50) ― комбинацию α1-адреноблокаторов (тамсулозин/силодозин) и курс воздействия поляризованным светом. Для оценки эффективности лечения проанализированы следующие показатели: критерий SFR (stone-free rate), время экспульсии конкрементов, уровень болевого синдрома, частота послеоперационных осложнений.</p> <p><bold>Результаты.</bold> Комбинированная литокинетическая терапия приводит к наибольшей частоте достижения статуса stone-free, т.е. полного отсутствия камней и их фрагментов после операции (88,0%), что достоверно выше, чем в контроле (60,0%; <italic>p</italic> &lt;0,001). Показатель SFR в группе полихроматического поляризованного света 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). Ультразвуковое исследование в динамике показало достоверно более быстрое уменьшение размеров остаточных фрагментов в исследуемых группах. Послеоперационные осложнения встречались реже в группах 2 и 3. Побочных действий от применения α1-адреноблокаторов не отмечено.</p> <p><bold>Заключение.</bold> Комбинированная литокинетическая терапия α1-адреноблокаторами и поляризованным светом у детей ассоциируется с более высокой частотой полного отхождения фрагментов конкрементов после дистанционной ударно-волновой литотрипсии по сравнению со стандартной терапией, а также со снижением потребности в анальгетиках.</p></trans-abstract><kwd-group xml:lang="en"><kwd>children</kwd><kwd>urolithiasis</kwd><kwd>extracorporeal shock wave lithotripsy</kwd><kwd>lithokinetic therapy</kwd><kwd>alpha-1-adrenergic blockers</kwd><kwd>polarized light</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>мочекаменная болезнь</kwd><kwd>дистанционная ударно-волновая литотрипсия</kwd><kwd>литокинетическая терапия</kwd><kwd>альфа-1-адреноблокаторы</kwd><kwd>поляризованный свет</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kyarimov IA.
