Group 1, 90 patients (retrospective assessment), underwent standard rRP, group 2, 46 patients (prospective assessment), underwent rRP modified by bladder neck preservation with a part of the proximal prostatic urethra. The clinical and pathological stages of PCa were assessed; the groups were compared to the parameter PSM. Statistical analysis was performed using nonparametric statistical methods.</p><p><bold>Results. </bold>Both groups were comparable in age and baseline total prostate specific antigen (PSA) but differed in prostate volume and Gleason score. Also, there were differences in clinical and pathological stages of PCa. PSM-patients had more aggressive PCa according to the International Society of Urological Pathology (ISUP) and TNM classifications and had higher progression risk prognosis stages. In PSM-patients, correlations were determined between prostate volume and baseline Gleason index (r = 0.338; p &gt;0.05); baseline total PSA and Gleason score before (r = 0.529; p &gt;0.05) and after (r = 0.310; p &gt;0.05) rRP, respectively. Nevertheless, the incidence of PSM among all subjects was 6.6 % of cases, while in groups 1 and 2 was 7.8 and 4.3 % of cases, respectively. In this way, surgical techniques that maximize bladder neck preservation with a part of proximal prostatic urethra have no significant effect on PSM. Ranges of total PSA, clinical stage of PCa, Gleason score and progression risk stages (prognostic group for PCa) were determined as predictors of PSM. Their use will make it possible to establish patient selection criteria for bladder neck preservation with proximal prostatic urethra during rRP.</p><p><bold>Conclusion.</bold> The identified predictors will allow determining during clinical staging minimal risks of detecting PSM. The rRP modified by bladder neck preservation with part of the proximal prostatic urethra does not increase the incidence of PSM compared to the standard rRP. The feasibility of this technique should be related to total PSA, clinical stage of PCa, Gleason score, and the progression risk stage.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Сохранение шейки мочевого пузыря при позадилонной радикальной простатэктомии (РПЭ) оказывает протективное действие на функцию удержания мочи в сравнении со стандартной РПЭ.</p><p><bold>Цель исследования</bold> – оценка возможных предикторов положительного хирургического края резекции (ПХКР).</p><p><bold>Материалы и методы</bold>. В исследование были включены 136 пациентов с локальным раком предстательной железы (РПЖ). Больным 1-й группы (n = 90) (ретроспективный анализ) выполнена стандартная позадилонная РПЭ, пациентам 2-й группы (n = 46) (проспективная оценка) – позадилонная РПЭ с сохранением шейки мочевого пузыря и части проксимальной простатической уретры. Оценены клиническая и патологическая стадии РПЖ. Сравнение в группах проведено по параметру хирургического края резекции. Статистический анализ выполнен методами непараметрической статистики.</p><p><bold>Результаты.</bold> Обе группы были сравнимы по возрасту, исходному уровню простатического специфического антигена (ПСА), но различны по объему предстательной железы и сумме баллов по шкале Глисона. Соответственно, определены различия в клинической и патологической стадиях РПЖ. Пациенты с ПХКР имели более агрессивный рак по классификациям Международного общества урологических патологов (ISUP) и TNM, более высокие стадии прогноза риска прогрессии. Корреляционные зависимости у пациентов с ПХКР выявлены между объемом предстательной железы и исходной суммой баллов по шкале Глисона (r = 0,338; p &gt;0,05); исходным уровнем ПСА и суммой баллов по шкале Глисона до и после РПЭ (r = 0,529; p &gt;0,05 и r = 0,310; p &gt;0,05 соответственно). Тем не менее частота ПХКР в целом составила 6,6 %: 7,8 и 4,3 % в 1-й и 2-й группах соответственно. Применение хирургических приемов, максимально сохраняющих шейку мочевого пузыря и часть уретры, не оказывает значимого отрицательного влияния на частоту ПХКР. Предикторами ПХКР явились интервалы значений уровня общего ПСА, клиническая стадия РПЖ, сумма баллов по шкале Глисона и степень риска прогрессирования заболевания, что позволяет определять условия отбора пациентов для сохранения шейки мочевого пузыря и части уретры при выполнении РПЭ.</p><p><bold>Заключение</bold>. Установленные предикторы позволяют во время клинического стадирования прогнозировать минимальные риски ПХКР. Сохранение шейки мочевого пузыря и части проксимальной простатической уретры не приводит к повышению частоты ПХКР по сравнению со стандартной техникой РПЭ. Возможность применения данного технического приема следует соотносить с уровнем общего ПСА, клиническим стадированием, суммой баллов по шкале Глисона и степенью риска прогрессирования РПЖ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>retropubic radical prostatectomy</kwd><kwd>positive surgical margin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>позадилонная радикальная простатэктомия</kwd><kwd>положительный хирургический край</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was performed without external funding</funding-statement><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Medvedev V.L., Lysenko V.V., Rosha L.G. et al.
