While the beneficial effects of stenting are well established, certain negative aspects remain insufficiently discussed and studied.</p> <p><bold>Aim: </bold>To evaluate the quality of life of children with urolithiasis during the period of JJ stenting.</p> <p><bold>Materials and Methods: </bold>The study included 29 children with urolithiasis aged 2.8 to 17.9 years who underwent indwelling JJ stent placement as the first stage of surgical treatment. Quality of life was assessed prospectively in the first days after stent removal using a structured questionnaire developed by the authors. The survey included questions on pain severity, irritative urinary symptoms, general well-being, and the impact of the stent on daily activities. Additionally, urinalysis parameters were analyzed. Statistical analysis was performed using non-parametric methods. Differences were considered statistically significant at p &lt; 0.05.</p> <p><bold>Results: </bold>More than half of the patients (55.2%) reported moderate or severe pain during the stenting period; the mean pain score was 3.1 (median 2). Pain during urination was observed in 37.9% of children (mean 2.8, median 1). A moderate positive correlation was found between flank/abdominal pain and pain during urination (ρ = 0.475; p = 0.009). No association was identified between age, sex, and pain severity (p &gt; 0.05). Leukocyturia ranged from 18.8 to 1303.8 cells/µL; a positive urine culture was detected in 7 of 21 examined patients (33.3%). No significant association was found between leukocyte count and bacteriuria (p &gt; 0.05). Stent duration was not significantly associated with pain severity, leukocyturia, or bacteriuria (p &gt; 0.05). Limitations in daily activity were reported in 69% of patients; however, in 65.5% of cases, parents did not report overall deterioration in the child’s general condition.</p> <p><bold>Conclusion: </bold>An indwelling JJ stent exerts a multifaceted impact on children, contributing to pain, irritative urinary symptoms, and limitations in daily activities. The use of structured questionnaires allows objective assessment of symptoms, improves the sensitivity of clinical monitoring, and may help optimize stent characteristics and duration in order to minimize adverse effects.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование</bold>. Использование внутреннего стента у пациентов с мочекаменной болезнью является рутинной практикой при различных клинических ситуациях. Хорошо изучены положительные эффекты стентирования, при этом некоторые его негативные аспекты не так широко обсуждаются. <bold>Цель</bold>. Оценить качество жизни детей с мочекаменной болезнью в период стентирования.<bold>Материалы и методы. </bold>В исследование включены 29 детей с мочекаменной болезнью, в возрасте от 2,8 до 17,9 лет, которым был установлен внутренний JJ-стент в качестве первого этапа хирургического лечения. Оценка качества жизни проводилась проспективно в первый дни после удаления стента. Использован разработанный нами структурированный опросник, включавший вопросы о выраженности болевого синдрома, ирритативных симптомах, общем самочувствии и влиянии стента на повседневную активность. Дополнительно анализировались показатели мочи. Статистическая обработка данных выполнялась с использованием непараметрических методов. Различия считались статистически значимыми при p &lt; 0,05.<bold>Результаты</bold>. Более половины пациентов (55,2%) отмечали умеренную или сильную боль в период стентирования, при этом средний уровень боли составил 3,1 балла (медиана 2 балла). Боль при мочеиспускании выявлена у 37,9% детей (среднее 2,8 балла, медиана 1 балл). Обнаружена умеренная положительная корреляция между болью в пояснице/животе и болью при мочеиспускании (ρ=0,475; p=0,009). Связи между возрастом, полом и выраженностью болевого синдрома не выявлено (p&gt;0,05). Лейкоцитурия варьировала от 18,8 до 1303,8 клеток/мкл; положительный посев мочи зарегистрирован у 7 из 21 обследованного пациента (33,3%). Достоверной связи между уровнем лейкоцитов и бактериурией не установлено (p&gt;0,05). Также не выявлено статистически значимой связи между длительностью стентирования и выраженностью болевого синдрома, лейкоцитурией или бактериурией (p&gt;0,05). У большинства пациентов отмечалось ограничение повседневной активности (69%), однако в целом родители в 65,5% случаев не отмечали ухудшения общего состояния ребенка.<bold>Заключение</bold>. Внутренний JJ-стент оказывает многокомпонентное влияние на состояние ребенка. Стентирование сопровождается развитием болевых и ирритативных симптомов, а также ограничением повседневной активности. Использование структурированных опросников позволяет зафиксировать симптомы, повысить чувствительность клинического мониторинга и в перспективе оптимизировать выбор характеристик стента и сроки его нахождения с целью минимизации неблагоприятных эффектов.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>urology</kwd><kwd>urolithiasis</kwd><kwd>JJ stent</kwd><kwd>quality of life</kwd><kwd>questionnaire</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>урология</kwd><kwd>мочекаменная болезнь</kwd><kwd>JJ-стент</kwd><kwd>качество жизни</kwd><kwd>анкетирование</kwd><kwd>дети</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Collins SL, Moore RA, McQuay HJ.
