У здоровых мужчин во время эпизодов ночных эрекций происходит значительное повышение уровня рО2 в кавернозной ткани. Этот процесс обеспечивает достаточный уровень оксигенации и веществ, выделяемых под действием высокого давления, таких как простогландин-Е1 и оксид азота, подавляющих экспрессию трансформирующего фактора роста β1, тем самым предотвращая синтез коллагена и развитие фиброза в кавернозной ткани. У пациентов, перенесших нервосберегающую радикальную простатэктомию, ночные эрекции отсутствуют, гипоксия ингибирует выработку PGE-1, а нейропраксия — NO. За счёт продукции проапоптических и профибротических факторов развивается кавернозный фиброз с возникновением стойкой эректильной дисфункции. Роль применения вакуума в пенильной реабилитации с целью профилактики гипоксии кавернозной ткани полового члена до конца не ясна из-за отсутствия данных о газовом составе кавернозной крови в момент достижения вакуум-индуцированной эрекции.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Исследовать кавернозную кровь в момент достижения вакуум-индуцированной эрекции, проанализировать данные результаты с показателями международного индекса эректильной функции и со значениями пенильной гемодинамики.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включены 15 пациентов с раком предстательной железы и сохранной половой функцией. Средний возраст мужчин составил 57,87 ± 4,36 лет. Всем пациентам проводили предоперационную комплексную оценку эректильной функции: заполнение анкеты международного индекса эректильной функции, фармакодопплерографию сосудов полового члена. Непосредственно перед операцией выполняли забор пенильной крови в момент достижения вакуум-индуцированной эрекции. Для дифференцировки артериальной и венозной крови проводили оценку газового состава и оксигенации за счёт определения значений парциального давления кислорода, углекислого газа и сатурации согласно утверждённым нормам. Статистическую обработку данных проводили с использованием программы PASW Statistics 22 (IBM SPSS, IBM Corp., Чикаго, ИЛ, США).</p></sec><sec><title>Результаты</title><p>Результаты. В зависимости от значений газового состава и уровня содержания кислорода кавернозной крови пациенты были распределены на три группы. В группу I вошли 4 (26,7%) пациента с преобладанием артериальной крови, в группу II — 4 (26,7%) пациента с венозной кровью и в группу III — 7 (46,7%) пациентов со смешанным составом кавернозной крови. Средний балл международного индекса эректильной функции в группе I составил 23,5 [21,0; 25,0], в группе II — 22,0 [21,0; 24,0] и в группе III — 24,0 [19,0; 25,0]. Пиковая систолическая скорость (см/с) в группе I составила 40,1 [35,1; 45,2], в группе II — 35,9 [29,5; 50,2], в группе III — 32,5 [32,5; 34,4]. Конечно-диастолическая скорость в группе I составила 2,52 [0,55; 10,5], в группе II — 8,3 [2,9; 10,8], в группе III — 7,5 [7,5; 9,0]. Индекс резистентности в группе I составил 0,87 [0,77; 0,98], в группе II — 0,75 [0,63; 0,94], в группе III — 0,75 [0,73; 0,75].</p></sec><sec><title>Заключение</title><p>Заключение. Вакуум-профилактика эректильной дисфункции может быть методом выбора программы пенильной реабилитации у пациентов после нервосберегающей радикальной простатэктомии, особенно на раннем послеоперационном этапе в период нейропраксии. Применение вакуумных устройств целесообразно назначать только пациентам с сохранным вено-окклюзивным механизмом, что должно быть подтверждено с помощью фармакодопплерографии сосудов полового члена.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. In healthy men, a significant increase in pO2 in the cavernous tissue occurs during episodes of nocturnal erections. This process ensures sufficient oxygenation and high-pressure substances such as prostaglandin-E1 and nitric oxide. These substances suppress the expression of transforming growth factor β1, thereby preventing collagen synthesis and the development of cavernous fibrosis. In patients undergoing nerve-sparing radical prostatectomy, nocturnal erections are absent, hypoxia inhibits the production of PGE-i, and neuropraxia inhibits NO. Thus, cavernous fibrosis develops through the production of pro-apoptotic and profibrotic factors, resulting in persistent erectile dysfunction. The importance of a vacuum in penile rehabilitation for the prevention of penile cavernous hypoxia is not fully understood. This is due to the deficiency of data on the gas composition of cavernous blood when a vacuum-induced erection is achieved.</p></sec><sec><title>Purpose of the study</title><p>Purpose of the study. To investigate the cavernous blood at the time of vacuum-induced erection, to analyze the obtained results with the International Index of Erectile Function score and with the values of penile hemodynamics.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included i5 patients with prostate cancer and preserved sexual function. The average age of all men was 57.87 ±4.36 years. All patients underwent a preoperative comprehensive assessment of erectile function: International Index of Erectile Function questionnaire, dynamic duplex penile ultrasound. Immediately prior to the surgery, penile blood was collected at the time of achieving a vacuum-induced erection. The gas composition and oxygenation were assessed using the values of the partial oxygen pressure, carbon dioxide and saturation in accordance with the approved standards to differentiate arterial and venous blood. Statistical data processing was carried out using the PASW Statistics 22 software (IBM SPSS, IBM Corp., Chicago, IL, USA)</p></sec><sec><title>Results</title><p>Results. All patients were divided into 3 groups depending on the gas composition and oxygen level of the cavernous blood. Group I included 4 (26.6%) patients with a predominance of arterial blood, group II — 4 patients (26.6%) with venous blood and group III — 7 patients (46.6%) with a mixed composition of cavernous blood. The average International Index of Erectile Function score in group I was 23.5 [2i.0; 25.0], in group II — 22.0 [2i.0; 24.0] and in group III — 24.0 [i9.0; 25.0]. Peak systolic velocity (cm/s) in group I was 40.i [35.i; 45.2], in group II — 35.9 [29.5; 50.2], in group III — 32.5 [32.5; 34.4]. End-diastolic velocity (cm/s) in group I was 2.52 [0.55; i0.5], in group II — 8.3 [2.9; i0.8], in group III — 7.5 [7.5; 9.0]. Resistive index in group I was 0.87 [0.77; 0.98], in group II — 0.75 [0.63; 0.94], in group III — 0.75 [0.73; 0.75].</p></sec><sec><title>Conclusions</title><p>Conclusions. Vacuum prophylaxis may be the method of choice for penile rehabilitation in patients after nerve-sparing radical prostateectomy, especially in the early postoperative period during neuropraxia. The use of vacuum devices should be prescribed to patients with preserved veno-occlusive mechanism, which should be confirmed by dynamic duplex penile ultrasound.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гипоксия кавернозной ткани</kwd><kwd>пенильная реабилитация</kwd><kwd>вакуум-индуцированная эрекция</kwd><kwd>эректильная дисфункция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cavernous hypoxia</kwd><kwd>penile rehabilitation</kwd><kwd>vacuum-induced erection</kwd><kwd>erectile dysfunction</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">Qian SQ, Gao L, Wei Q, Yuan J.
