В настоящее время установлены показания к выбору интракорпоральной литотрипсии камней мочеточника различной локализации при размерах до 10 мм включительно. Однако в случае проксимальной обструкции мочеточника камнем размерами более 10 мм согласительного мнения о предпочтениях данного вида хирургии перед другими существующими не достигнуто. Это обусловлено различием в существующих исследовательских данных по эффективности и безопасности эндоскопической уретеролитотрипсии. Тем самым проведение в настоящее время сравнительных исследований в данном направлении актуально.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследованы 54 пациента с камнями проксимального отдела мочеточника размерами более 10 мм. Всем пациентам выполнена лазерная контактная уретеролитотрипсия (ЛазКУЛТ) при помощи полуригидного уретероскопа. Стратификация на группы по размерам камней согласно актуальной классификации AUA: Группа А (n - 46), размеры конкрементов от 11 до 20 мм включительно. Группа Б (n - 8), размеры камней свыше 20 мм. Под эффективностью лечения понимали достижение уровня "Stone Free" после выполнения литотрипсии. Под неэффективностью лечения подразумевали невозможность полного удаления конкремента из мочеточника в пределах одного оперативного вмешательства без расширения его границ. Статистическую обработку данных проводили с использованием статистического пакета STATISTICA 10 (StatSoft Inc., США) непараметрическими методами анализа данных.</p></sec><sec><title>Результаты</title><p>Результаты. Более крупные камни характеризовались большей плотностью. Симптомы обструкции (гидронефроз, тошнота и рвота, макрогематурия) имели место чаще при размерах камней &gt;20 мм. Длительность лечения в группах подобна, несмотря на различия в количестве осложнений и частоте послеоперационного стентирования мочеточника. При этом время операции находилось в зависимости от размеров и плотности камня. Эффективность хирургии в группах сравнима, 78,3% (группа А) против 75,0% (группа Б).</p></sec><sec><title>Выводы</title><p>Выводы. При камнях более 20 мм чаще встречаются изменения стенки мочеточника воспалительного и деструктивного характера, что влияет на частоту развития послеоперационных осложнений. Повышение размеров и плотности камней определяют увеличение продолжительности операции и повышение частоты проксимальной миграции фрагментов. Важной особенностью ЛазКУЛТ является отсутствие статистических различий в эффективности метода при различных размерах камней. Кроме того, для всех размеров камней период достижения уровня Stone Free не превышает одного дня. Выполнение ЛазКУЛТ крупных камней проксимального отдела мочеточника в первые сутки от момента поступления пациента в клинику сопровождается большей эффективностью лечения и статистически значимо определяет снижение частоты послеоперационных осложнений.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Currently, indications for intracorporeal lithotripsy of ureteral stones with sizes up to 10 mm inclusively of different localization are established. However, there is no consensus was reached on the preferences of this type of surgery over other existing one in the case of proximal ureteral obstruction by a stones greater than 10 mm in size. Endoscopic ureterolithotripsy is associated with existing studies on the effectiveness and safety of this method. Thus, it is important to continue conducting comparative studies in this direction.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 54 patients with proximal ureteral stones larger than 10 mm in size were investigated. All patients underwent Semi-Rigid Ureteroscopy and Laser Lithotripsy (SRULL) using a semi-rigid ureteroscope. Patients was stratified into several groups in accordance with the size of stones according to the actual AUA classification: group A (n - 46), the dimensions of ureteral stones from 11 to 20 mm inclusive and group B (n - 8), the size of stones over 20 mm. Criterion for the effectiveness of treatment was to achieve the "Stone Free" level after performing lithotripsy. Indicator of treatment failure was the impossibility of complete removal of ureteral stone within one surgical procedure without its expansion. Statistical data processing was performed using non-parametric data analysis methods applying the STATISTICA 10 (StatSoft Inc., USA) software package.</p></sec><sec><title>Results</title><p>Results. Larger stones compared to higher density. Obstruction symptoms such as hydronephrosis, nausea and vomiting, gross hematuria were more common with stones &gt; 20 mm. Treatment duration in patient groups is similar despite differences in the number of complications and the incidence of postoperative ureteral stenting. At the same time, operation time depended on stone size and density. Surgery efficacy in patient groups was comparable and met 78.3% in group A versus 75.0% in group B.</p></sec><sec><title>Conclusion</title><p>Conclusion. Inflammatory and destructive changes in the ureter wall are more common with stones greater than 20 mm, which affects the incidence of postoperative complications. Increasing the operation duration and frequency of proximal fragments' migration are determined by increasing of the stones' size and density. SRULL important feature is the lack of statistical difference in the effectiveness with the different sizes of stones. In addition, the achievement of "Stone Free" level for various size's stones does not exceed one day. Performing a SRULL of proximal ureter's large stones on the first day of a patient's hospitalization is accompanied by greater treatment efficacy. It statistically reliably determines the reduction in the frequency of postoperative complications.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мочекаменная болезнь</kwd><kwd>уретеролитиаз</kwd><kwd>крупные камни мочеточника</kwd><kwd>уретероскопия</kwd><kwd>лазерная литотрипсия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>urolithiasis</kwd><kwd>ureterolithiasis</kwd><kwd>large ureteral stone</kwd><kwd>ureteroscopy</kwd><kwd>laser lithotripsy</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">Каприн А.Д., Аполихин О.И., Сивков А.В., Солнцева Т.В., Комарова В.А.
