Recurrence of BNS was confirmed in each case by the flexible urethroscopy in the outpatient settings, after which the patient was included in the protocol of serial balloon dilation of the bladder neck. Incision of the bladder neck was performed using a thulium Fiber laser U3 (IRE-Polus) with power settings of 1 J, 30 Hz, 30 W or bipolar energy with the PlasmaNeedle electrode (Olympus). Serial balloon dilation was performed three weeks after repeated incision of the bladder neck. Before each session of balloon dilation, the following parameters were assessed in all patients: the total International Prostate Symptom Score (IPSS) and quality of life (QoL) score, Qmax and postvoid residual.</p> <p><bold>Results</bold><bold>.</bold> Contracture stabilization at a urodynamically acceptable level (Qmax is higher than 12 ml/s and QoL is less than 3) was observed in 73.3% (<italic>n</italic>=22) of patients with a median follow-up of 10 months. Effective treatment required a median of 6 sessions of balloon dilatation. 4 out of 8 patients with recurrent BNS refused further participation in the study, while the remaining 4 underwent re-incision of the bladder neck followed by inclusion in the repeat balloon dilatation program, which was successful, thereby increasing the primary efficiency to 86.7%. Based on the Kaplan-Meier survival analysis, it was found that the longer the time since the start of serial balloon dilation, the lower the chance of recurrence of BNS. In terms of safety, no patient experienced complications associated with serial balloon dilation.</p> <p><bold>Conclusion</bold><bold>.</bold> Serial balloon dilatation of the bladder neck under transrectal ultrasound control using a urethral catheter with an ultrasound-induced drug coating with methylprednisolone is an effective and safe technique that can be offered to patients to prevent recurrent BNS.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Одним из наиболее перспективных малоинвазивных методов профилактики рецидива рубцовой деформации шейки мочевого пузыря (РДШМП) является баллонная дилатация рубцово-деформированной шейки мочевого пузыря под трансректальным ультразвуковым контролем с использованием уретрального катетера с УЗ-индуцируемым лекарственным покрытием с метилпреднизолоном.</p> <p><bold>Цель исследования.</bold> Оценка эффективности и безопасности программной баллонной дилатации с использованием уретрального катетера с УЗ-индуцируемым лекарственным покрытием с метилпреднизолоном для профилактики рецидива РДШМП после эндоскопических операций на предстательной железе.</p> <p><bold>Материалы и методы.</bold> В исследование включены 30 пациентов с рецидивом РДШМП, которые были внесены в протокол программной баллонной дилатации ШМП. Рецидив РДШМП подтверждался в каждом случае по результатам фиброуретроскопии на амбулаторном этапе, после чего пациент включался в протокол баллонной дилатации РДШМП. Инцизия шейки мочевого пузыря всем пациентам выполнялась с использованием тулиевого волоконного лазера Fiber laser U3 (ИРЭ-Полюс), режим работы – 1 Дж, 30 Гц, 30 Вт либо с использованием биполярной энергии электродом PlasmaNeedle (Олимпус). Программная баллонная дилатация выполнялась через три недели после повторной инцизии ШМП. Перед каждым сеансом баллонной дилатации у всех пациентов оценивались следующие параметры: сумма баллов по шкале суммарной оценки симптомов при заболеваниях предстательной железы (International Prostate Symptom Score, IPSS) и качества жизни (QoL), Qmax и ООМ.</p> <p><bold>Результаты.</bold> Стабилизация рубца на уродинамически приемлемом уровне (Qmax выше 12 мл/с и QoL – менее 3) отмечалась у 73,3% (n=22) пациентов при медиане наблюдения 10 месяцев. Для эффективного лечения потребовалось шесть сеансов баллонной дилатации по медиане. Четыре из восьми пациентов с рецидивом РДШМП отказались от дальнейшего участия в исследовании, в то время как оставшимся четырем была повторно выполнена инцизия ШМП с последующим включением в программу баллонной дилатации, которая оказалась успешной, тем самым увеличив первичную эффективность до 86,7%. На основании проведенного анализа выживаемости Каплана-Мейера было установлено, что, чем больше времени прошло от начала выполнения сеансов баллонной дилатации, тем меньше шанс наличия рецидива РДШМП. В отношении безопасности ни у одного пациента не было зафиксировано осложнений, связанных с выполнением программной баллонной дилатации.</p> <p><bold>Заключение.</bold> Программная баллонная дилатация с использованием уретрального катетера с УЗ-индуцируемым лекарственным покрытием с метилпреднизолоном является эффективной и безопасной методикой, которая может быть предложена пациентам для профилактики рецидива РДШМП.</p></trans-abstract><kwd-group xml:lang="en"><kwd>BPH</kwd><kwd>TURP</kwd><kwd>cicatricial deformity of the bladder neck</kwd><kwd>bladder neck sclerosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ДГПЖ</kwd><kwd>ТУРП</kwd><kwd>рубцовая деформация шейки мочевого пузыря</kwd><kwd>склероз шейки мочевого пузыря</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Yan P., Cui Y., Huang Y., et al.
