While the beneficial effects of stenting are well established, certain negative aspects remain insufficiently discussed and studied.</p> <p><bold>AIM: </bold>This study aimed to evaluate the quality of life of children with urolithiasis during the period of JJ stenting.</p> <p><bold>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 our own structured questionnaire. 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 <italic>p</italic> &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 points (median 2 points). Pain during urination was observed in 37.9% of children (mean 2.8 points, median 1 point). A moderate positive correlation was found between flank/abdominal pain and pain during urination (ρ = 0.475; <italic>p </italic>= 0.009). No association was identified between age, sex, and pain severity (<italic>p</italic> &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 (<italic>p</italic> &gt; 0.05). Stent duration was not significantly associated with pain severity, leukocyturia, or bacteriuria (<italic>p</italic> &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:<italic> </italic></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 — рутинная практика при различных клинических ситуациях. Хорошо изучены положительные эффекты стентирования, при этом некоторые его негативные аспекты не так широко обсуждаются.</p> <p><bold>Цель исследования.</bold> Оценить качество жизни детей с мочекаменной болезнью в период стентирования.</p> <p><bold>Методы.</bold> В исследование включены 29 детей с мочекаменной болезнью, в возрасте от 2,8 до 17,9 года, которым был установлен внутренний JJ-стент в качестве первого этапа хирургического лечения. Оценка качества жизни проведена проспективно в первые дни после удаления стента. Использован разработанный авторами 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 выполнена с использованием непараметрических методов. Различия считали статистически значимыми при <italic>p</italic> &lt; 0,05.</p> <p><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; <italic>p</italic>=0,009). Связи между возрастом, полом и выраженностью болевого синдрома не выявлено (<italic>p</italic> &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 (<italic>p</italic> &gt;0,05). Также не выявлено статистически значимой связи между длительностью стентирования и выраженностью болевого синдрома, лейкоцитурией или бактериурией (<italic>p</italic> &gt;0,05). У большинства пациентов указано ограничение повседневной активности (69%), однако в целом родители в 65,5% случаев не отмечали ухудшения общего состояния ребёнка.</p> <p><bold>Заключение.</bold> Внутренний JJ-стент оказывает многокомпонентное влияние на состояние ребёнка. 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>论证。在尿石症患者中使用内支架管是处理各种临床情况的常规做法。支架手术的积极效果已得到充分研究，而一些负面影响则未获广泛讨论。</p> <p>目的。评估输尿管支架置入期间儿童泌尿系结石患者的生活质量。</p> <p>方法。该研究纳入了29名年龄介于2.8至17.9岁之间的尿路结石患儿，均将内置双J管置入术作为外科治疗的第一阶段方案。在支架移除后的最初几天前瞻性地进行了生活质量评估。作者采用自行设计的结构化问卷进行评估，内容涵盖疼痛程度评估、刺激性症状、整体健康状况以及双J管对日常生活的影响。另外还对尿液指标进行了分析。数据的统计分析采用了非参数方法进行处理。当p值小于0.05时，认为差异具有统计学意义。</p> <p>结果。超过半数（55.2%）患者在放置支架期间出现中度或重度疼痛，平均疼痛等级为3.1分（中位数2分）。37.9%的患儿存在排尿疼痛（平均2.8分，中位数1分）。研究发现腰腹部疼痛与排尿疼痛呈中等程度正相关（ρ=0.475；p=0.009）。年龄、性别与疼痛程度未显示显著关联（p＞0.05）。白细胞尿波动于18.8-1303.8细胞/微升；21例受检患者中7例（33.3%）尿培养阳性。白细胞水平与菌尿症无显著相关性（p＞0.05）。支架留置时长与疼痛程度、白细胞尿或菌尿症亦无统计学显著关联（p＞0.05）。 69%患者日常活动受限，但65.5%的家长总体认为患儿健康状况未恶化。</p> <p>结论。内置双J管对患儿状况产生多维度影响。支架置入伴随疼痛刺激症状发生及日常活动受限。采用结构化问卷有助于症状记录，提升临床监测敏感性，并为优化支架参数选择及留置时长提供依据，从而最大限度降低不良反应。</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><kwd-group xml:lang="zh"><kwd>泌尿外科</kwd><kwd>尿石症</kwd><kwd>双J管</kwd><kwd>生活质量</kwd><kwd>问卷调查</kwd><kwd>儿童</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.
