Рубцовая деформация шейки мочевого пузыря (РДШМП) является клинически значимым поздним осложнением трансуретрального хирургического лечения гиперплазии предстательной железы (ГПЖ) и нередко характеризуется рецидивирующим течением. В связи с ограниченной эффективностью повторных эндоскопических вмешательств сохраняется необходимость в разработке минимально инвазивных методов, направленных на профилактику повторного рубцевания и длительное сохранение проходимости шейки мочевого пузыря.Цель исследования. Оценить эффективность этапной баллонной дилатации (БД) уретральным катетером с метилпреднизолоновым покрытием.Материалы и методы. В проспективное наблюдательное исследование включены 56 пациентов с рецидивирующей РДШМП после трансуретральных вмешательств по поводу ГПЖ. Всем пациентам первым этапом выполняли трансуретральную инцизию рубцово-изменённого участка, после чего через 3 недели начинали программу этапной БД уретральным катетером с метилпреднизолоновым покрытием под трансректальным ультразвуковым контролем. Эффективность лечения оценивали по динамике IPSS, QoL, Qmax, объёму остаточной мочи (ООМ), а также по частоте рецидивов и показателям безрецидивной выживаемости.Результаты. После 1-го курса лечения отмечено выраженное улучшение функциональных показателей: IPSS снизился с 17,4 до 8,4 балла, QoL — с 3,6 до 1,9 балла, ООМ — с 50,2 до 10,7 мл. У пациентов, которым потребовался 2-й курс БД, также зарегистрирована положительная динамика: IPSS уменьшился с 16,0 до 4,5 балла, QoL — с 3,0 до 1,6 балла, Qmax увеличилась с 10,5 до 20,9 мл/с, а ООМ снизился с 23,8 до 7,4 мл. После 1-го курса положительный эффект был достигнут у 44 (78,6%) пациентов. Повторный курс потребовался 12 пациентам, из которых у 7 был получен стабильный клинический результат. После 2 курсов непосредственная эффективность методики составила 91,1%, однако при медиане наблюдения 34,4 месяца итоговая эффективность составила 78,6%, а рецидив был зарегистрирован у 21,4% пациентов. По данным анализа Kaplan – Meier, безрецидивная выживаемость составила 91,1% через 12 месяцев, 80,4% через 24 месяца и 77,4% через 36 месяцев наблюдения; при этом основная часть рецидивов РДШМП регистрировалась в течение первых 2 лет после включения пациентов в программу этапной БД. Заключение. Этапная баллонная дилатация уретральным катетером с метилпреднизолоновым покрытием после трансуретральной инцизии является перспективным минимально инвазивным методом лечения рецидивирующей рубцовой деформации шейки мочевого пузыря. Методика обеспечивает значимое улучшение субъективных и объективных показателей мочеиспускания у большинства пациентов, однако требует длительного динамического наблюдения, особенно в первые 2 года после начала лечения.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Bladder neck contracture (BNC) is a clinically significant late complication of transurethral surgical treatment for benign prostatic hyperplasia (BPH) and is often characterized by a recurrent course. Given the limited effectiveness of repeated endoscopic procedures, there remains a need to develop minimally invasive approaches aimed at preventing recurrent scarring and maintaining long-term bladder neck patency.Objective. To evaluate the effectiveness of staged balloon dilation using a methylprednisolone drug-coated urethral catheter.Materials &amp; methods. This prospective observational study included 56 patients with recurrent BNC after transurethral interventions for BPH. As the first stage of treatment, all patients underwent transurethral incision of the scarred area, followed three weeks later by staged balloon dilation using a methylprednisolone drug-coated urethral catheter under transrectal ultrasound guidance. Treatment efficacy was assessed based on changes in IPSS, QoL, Qmax, post-void residual urine volume (PVR), recurrence rate, and recurrence-free survival.Results. After the first treatment course, a marked improvement in functional parameters was observed: IPSS decreased from 17.4 to 8.4 points, QoL — from 3.6 to 1.9 points, and PVR — from 50.2 to 10.7 mL. Patients who required a second course of balloon dilation also demonstrated favorable dynamics: IPSS decreased from 16.0 to 4.5 points, QoL — from 3.0 to 1.6 points, Qmax increased from 10.5 to 20.9 mL/s, and PVR decreased from 23.8 to 7.4 mL. After the first course, a positive clinical effect was achieved in 44 patients (78.6%). A repeated course was required in 12 patients, of whom 7 achieved a stable clinical result. After two courses, the immediate effectiveness of the technique was 91.1%; however, at a median follow-up of 34.4 months, the final effectiveness was 78.6%, with recurrence recorded in 21.4% of patients. According to Kaplan—Meier analysis, recurrence-free survival was 91.1% at 12 months, 80.4% at 24 months, and 77.4% at 36 months. Most BNC recurrences occurred within the first 2 years after inclusion in the staged balloon dilation program.Conclusion. Staged balloon dilation using a methylprednisolone drug-coated urethral catheter after transurethral incision is a promising minimally invasive treatment option for recurrent bladder neck contracture. The technique provides significant improvement in both subjective and objective voiding parameters in most patients; however, long-term follow-up is required, particularly during the first 2 years after treatment initiation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рубцовая деформация шейки мочевого пузыря</kwd><kwd>баллонная дилатация</kwd><kwd>метилпреднизолон</kwd><kwd>лекарственное покрытие</kwd><kwd>трансуретральная инцизия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bladder neck contracture</kwd><kwd>balloon dilation</kwd><kwd>methylprednisolone</kwd><kwd>drug coating</kwd><kwd>transurethral incision</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания ФГБОУ ВО «МГУ им.
