Background . Approximately 50 % of cases of infertility in couples are attributable to male factor. One of the most common causes of male infertility is varicose dilation of pampiniform plexus veins in spermatic cord, or varicocele. However, the fact that only in 10-45 % of cases microsurgical subinguinal varicocelectomy leads to a spontaneous pregnancy in a couple urges further search for a diagnostic marker which would be able to predict the success of surgical treatment of varicocele preoperatively. Aim . To study the features of lipid profile of seminal plasma in patients with varicocele and to evaluate the possibility of using lipidomic analysis of seminal plasma for patient selection prior to surgical treatment for varicocele. Materials and methods . Fifty three patients from infertile couples with varicocele and altered seminal parameters aged 18 to 44 years underwent microsurgical varicocelectomy as described by Marmar. All patients were treated in one department. The control group included 24 healthy normozoospermic men without varicocele who had proven fertility. The material for the study was the seminal plasma of men, lipid composition of which was determined by mass spectrometry. Results . No significant differences were found in lipid profiles of seminal plasma from men in control group and varicocele group, as well as in lipid profiles of seminal plasma obtained before and after surgery in same patients. Comparison of lipid profiles of seminal plasma provided by patients before microsurgical varicocelectomy, who had clinical effect ( n = 15) and who did not have clinical effect ( n = 16), revealed differences in level of HexCer-NDS d20:0/18:0 in the positive ion test and in levels of 8 other lipids in the negative ion test. These lipids are related to the oxidation of phospholipids, cardiolipins and phosphatidylethanolamines. Conclusion . The lipid profile of seminal plasma of patients who had clinical response to varicocele surgery is significantly different from the lipid profile of seminal plasma of non-responder patients.
背景。大约50%的夫妇不孕病例可归因于男性因素。男性不育症最常见的原因之一是精索旁丛静脉曲张或精索静脉曲张。然而,只有10- 45%的腹股沟下精索静脉曲张显微手术导致夫妇自然妊娠,这一事实促使我们进一步寻找一种能够预测术前精索静脉曲张手术治疗成功的诊断标志。的目标。目的研究精索静脉曲张患者精浆脂质特征,探讨精索静脉曲张术前精浆脂质组学分析用于患者选择的可能性。材料和方法。53例18 - 44岁伴有精索静脉曲张和精子参数改变的不育夫妇接受了显微外科精索静脉曲张切除术。所有患者均在同一科室治疗。对照组包括24名无精索静脉曲张的健康正常精子男性。该研究的材料是男性的精液,其脂质组成由质谱测定。结果。对照组和精索静脉曲张组男性精浆脂质特征及同一患者手术前后精浆脂质特征均无显著差异。对比显微精索静脉曲张切除术前有临床效果(n = 15)和无临床效果(n = 16)患者提供的精浆脂质谱,发现正离子试验中HexCer-NDS d20:0/18:0水平和负离子试验中其他8种脂质水平存在差异。这些脂质与磷脂、心磷脂和磷脂酰乙醇胺的氧化有关。结论。精索静脉曲张手术有临床反应患者的精浆脂质与无反应患者的精浆脂质有显著差异。

Background . According to the contemporary data available contrast-enhanced computed tomography can be used to assess total and split kidney function. The Urology Clinic of the I.M. Sechenov First Moscow State Medical University, Ministry of Health of Russia (Sechenov University) utilizes mathematical processing of computed tomography data for the assessment of split kidney function. Aim . To evaluate the effect of main renal artery clamping (warm ischemia time) during partial nephrectomy for a unilateral tumor on the kidney function. Materials and methods . 33 patients of both sexes who underwent partial nephrectomy for unilateral kidney tumor were enrolled in the study. Prior to and 3–6 months after the surgery, 3D glomerular filtration rate (GFR), 3D perfusion, 3D volume of the renal parenchyma were evaluated by mathematical processing of computed tomography data with contrast enhancement. As well as that the dynamics of the total GFR (CKD-EPI equation) and total volume of the kidneys were assessed. Results . No significant changes were registered for both general functional renal parameters (creatinine level, total GFR, total volume of functioning renal parenchyma) and split 3D GFR. There were significant differences in 3D perfusion and kidney parenchyma volume prior and after partial nephrectomy. Conclusion . The results of the research highlight good reserve capacity the kidneys after partial nephrectomy with main renal artery clamping. The evidence that the non-operated kidney takes over the function of the resected kidney is based on the fact that there is an increase in its perfusion and volume of the kidney in the postoperative period. This state can also be regarded as a redistribution of functional loads between the kidneys, which is an adaptive mechanism in the postoperative period.
背景。根据现有的数据,对比增强计算机断层扫描可用于评估全肾功能和裂肾功能。俄罗斯卫生部谢切诺夫第一莫斯科国立医科大学(谢切诺夫大学)泌尿外科诊所利用计算机断层扫描数据的数学处理来评估分裂肾功能。的目标。探讨单侧肿瘤部分切除时肾主动脉夹持(热缺血时间)对肾功能的影响。材料和方法。33名因单侧肾肿瘤而行部分肾切除术的男女患者被纳入研究。术前及术后3-6个月,对ct数据进行增强处理,评估3D肾小球滤过率(GFR)、3D灌注、3D肾实质体积。同时评估肾脏总GFR (CKD-EPI方程)和肾脏总容积的动态变化。结果。一般肾功能参数(肌酐水平、总GFR、功能性肾实质总容积)和分离的3D GFR均无显著变化。肾部分切除术前后3D灌注及肾实质体积差异有统计学意义。结论。本研究结果显示,肾主动脉夹持术后,肾脏有良好的储备能力。非手术肾接管切除肾功能的证据是基于术后肾脏的灌注和体积增加。这种状态也可以看作是肾间功能负荷的重新分配,是术后的一种适应性机制。

Objective: diagnostics of erectile disorders within men with diabetic autonomic neuropathy and detection of rehabilitation methods of patients with erectile dysfunction (ED) affected diabetes mellitus (DM). Materials and methods . Thirty patients with DM were examined (15 patients with type 1 and 15 patients with type 2 respectively). Patients with DM had ED mainly of severe form (IIEF-5  from 6 to 16 points). According to the results of conducted examination the patients were prescribed the course of conservative therapy including hosphodiesterase in hibitors of type V, anticholinesterase drugs, drugs of thioctic acid. Conservative therapy was combined with shock wave therapy in the area of the penis. The group for comparison consisted of 15 healthy men (volunteers) without signs of ED (IIEF-5 21–22 points). Immune-enzyme analysis was used for detection of sex hormone status. Ultrasound, dopplerographic and X-ray methods were used for conduction of angiography of pool vessels of internal pudendal artery (IPA). Electroneuromyography of penis nerves was conducted. Results. According to the conducted research patients with DM were diagnosed with cavernous fibrosis, angiosclerosis of IPA and penis vessels in 100 % cases. Axonopathy of motor and sensory nerves of penis was detected in 100 % cases, stenosis and occlusion changes in IPA were detected in 42.9 % cases causing disorder and insufficiency in arterial perfusion in IPA pool. Conclusion. Denervation changes in sensory and motor nerves of penis and hemodynamicly significant perfusion disorders in IPA pool were principal pathogenetic factors of ED within the patients with DM. Decrease of reaction of IPA to the pharmacological stimulation was noted within patients with DM, which was caused by the angiosclerosis and loss of arterial wall elasticity. There was noted inefficiency of conservative therapy within patients with DM and ED at severe stage.
目的:探讨男性糖尿病自主神经病变患者勃起功能障碍的诊断及糖尿病(DM)伴勃起功能障碍患者的康复方法。材料和方法。30例糖尿病患者(1型15例,2型15例)。糖尿病患者以重度ED为主(IIEF-5从6分到16分)。根据检查结果,给予V型磷酸二酯酶抑制剂、抗胆碱酯酶药物、硫辛酸药物等保守治疗。保守治疗与阴茎部位冲击波治疗相结合。对照组为15名无ED症状的健康男性(志愿者)(IIEF-5 21-22分)。免疫酶分析法检测性激素状态。采用超声、多普勒、x线等方法对阴部内动脉池血管进行血管造影。行阴茎神经电肌图。结果。根据所进行的研究,100%的糖尿病患者诊断为海绵体纤维化、阴茎血管和阴茎血管硬化。阴茎运动神经和感觉神经轴突病变发生率100%,IPA狭窄和闭塞改变发生率42.9%,导致IPA池动脉灌注紊乱和不足。结论。阴茎感觉神经和运动神经的去神经支配改变以及血流动力学上明显的IPA池灌注障碍是糖尿病患者ED的主要发病因素。糖尿病患者IPA对药物刺激的反应下降,这是由于血管硬化和动脉壁弹性丧失所致。在重度糖尿病和ED患者中,保守治疗效率低下。

Subjects and methods. A total of 917 men from infertile couples with abnormal ejaculate indicators were examined. Their age was 34.1 ± 6.3 years; the infertility period was 4.6 ± 3.9 years. A retrospective analysis of their case histories, clinical examination, questioning to identify risk factors for infertility, and anthropometric measurements of weight and height were made. Weight was rated normal at a body mass index (BMI) of ≤ 24.9 kg/m2 ; overweight at 25.0–29.9 kg/m2 , and obesity at ≥ 30 kg/m2 . When identifying infertility risk factors, the investigators kept in mind 24 risk factors at the moment of examination or in the patient histories, which were grouped into 3 clusters: 1 – environmental factors and occupational hazards; 2 – evidence of congenital and acquired abnormalities; 3 – social and quality-of-life factors; this cluster also includes history and examination evidence of tuberculosis, sexually transmitted diseases, and other social diseases, such as hepatitis B and C, or human immunodeficiency infection. Then the men who did not show an exacerbation of somatic diseases, genetic anomalies associated with reproductive disorders, or an exacerbation of social diseases at the moment of examination were selected from the total sample. These were divided into 2 groups: normal weight and obese patients. The frequency of the above mentioned infertility risk factors and additionally the proportion of persons engaged in intellectual or manual labor were calculated in each group. Results and discussion. In the total sample, the frequency of infertility risk factors including occupational hazards and environmental factors was 40 %. Conclusion. The sociomedical risk factors of infertility make the most significant contribution to the development of male infecundity. Moreover, among the contemporary men there is a social group of persons at high risk of infertility; these are 30–40-year-old men who have constitutional prerequisites to the development of obesity accompanied by the high rate of chronic hepatitis, who are engaged in intellectual labor and experience frequent emotional stresses, for relief of which they regularly consume alcohol.
研究对象和方法。对917例射精指标异常的不育夫妇进行了检查。年龄34.1±6.3岁;不孕症期4.6±3.9年。回顾性分析他们的病史,临床检查,询问以确定不育的危险因素,并进行了体重和身高的人体测量。体重指数(BMI)≤24.9 kg/m2为正常;超重25.0 ~ 29.9 kg/m2,肥胖≥30 kg/m2。在确定不孕症危险因素时,研究人员在检查时或患者病史中考虑了24个危险因素,将其分为3类:1 -环境因素和职业危害;2 -先天性和后天性异常的证据;3 -社会和生活质量因素;这类病例还包括结核病、性传播疾病和其他社会疾病(如乙型和丙型肝炎或人类免疫缺陷感染)的病史和检查证据。然后从总样本中选择在检查时没有表现出躯体疾病恶化、与生殖障碍相关的遗传异常或社会疾病恶化的男性。这些患者被分为两组:正常体重和肥胖患者。计算各组中上述不孕危险因素的出现频率及从事脑力劳动或体力劳动的人数比例。结果和讨论。在总样本中,包括职业危害因素和环境因素在内的不孕危险因素的发生率为40%。结论。不育的社会医学风险因素对男性不育的发展贡献最大。此外,在当代男性中,存在着一个不育风险很高的社会群体;这些人是30 - 40岁的男性,他们具有肥胖的体质条件,并伴有慢性肝炎的高发率,他们从事智力劳动,经常经历情绪压力,为了缓解压力,他们经常饮酒。

Moreover, among the contemporary men there is a social group of persons at high risk of infertility; these are 30–40-year-old men who have constitutional prerequisites to the development of obesity accompanied by the high rate of chronic hepatitis, who are engaged in intellectual labor and experience frequent emotional stresses, for relief of which they regularly consume alcohol.","PeriodicalId":36603,"journal":{"name":"Andrologia i Genital''naa Hirurgia","volume":"17 1","pages":"47-53"},"PeriodicalIF":0.0,"publicationDate":"2016-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67774119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A clinical case of intermittent spermatic cord torsion demonstrates the difficulty of diagnosis of this rare disease. The patient have suffered 2 episodes of intermittent spermatic cord torsion which was interpreted as epididymitis and appendage torsion. Orchiopexy made only after the third episode, when the clinical diagnostic signs consistent with acute spermatic cord torsion. All cases of a recurring acute pain in the testicle require in-depth analysis because even a single episode of scrotal pain indicates ischemia of testicle with possible atrophy in the future.
一个临床病例的间歇性精索扭转表明诊断这种罕见的疾病的困难。患者曾发生2次间歇性精索扭转,解释为附睾炎和附属物扭转。只有在第三次发作后,临床诊断体征符合急性精索扭转时才行输卵管切除术。所有复发性睾丸急性疼痛的病例都需要深入分析,因为即使是一次阴囊疼痛也表明睾丸缺血,未来可能出现萎缩。

The paper focuses on the recommendations for chronic prostatitis treatment taking into the consideration the peculiarities of the pathogenesis and clinical picture of this disease. The paper demonstrates that the efficient chronic prostatitis treatment requires the new UPOINT prostatitis classification rather than traditional VIN NIDDK (1995) classification. The paper discusses the indications for various drug and non-drug interventions: antibiotics, alpha-blockers, M-cholinolytics, analgesics, antidepressants, phytodrugs, pelviс floor acupuncture and physiotherapy, psychotherapy.

Хронический простатит категории IIIВ/синдром хронической тазовой боли и сексуальные дисфункции 慢性前列腺炎/慢性盆腔疼痛和性功能障碍综合征

The paper reviews the literature on the topical urological problem category IIIB chronic nonbacterial prostatitis (CNBP)/chronic pelvic pain syndrome (CPPS) and sexual dysfunction in this abnormality. As of now, there is no precise information on the etiology and pathogenesis of CNBP/CPPS and sexual dysfunction in this disease. Despite a considerable body of published work, the disease remains inadequately studied and untreatable. The diagnosis of CNBP/CPPS is most likely to mask a high range of different conditions, including those when the prostate is only indirectly or by no means involved in the pathological process. Some factors, such as pudendal neuropathy with the development of chronic prostatitis, CPPB, vesical obstruction, and neuroautonomic disorders, may be etiological and pathogenetic simultaneously. The problem of CNBP therapy remains unsolved so far in spite of a diversity of used treatments. Therapeutic approaches are generally aimed only at improving quality of life in a patient. All existing treatments for chronic prostatitis imply for reducing the level of sexual dysfunction too as a desirable result. Hopes for improving the results of treatment are associated with progress in the diagnosis and differential diagnosis of these conditions, with the improvement and detailed elaboration of clinical classification of the disease, and with the accumulation of the valid clinical results characterizing the efficacy and safety of drugs in well-defined patient groups.
本文综述了泌尿系统问题类IIIB慢性非细菌性前列腺炎(CNBP)/慢性盆腔疼痛综合征(CPPS)和性功能障碍的文献。截至目前,关于CNBP/CPPS的病因和发病机制以及该疾病的性功能障碍尚无确切的信息。尽管发表了大量的研究成果,但对这种疾病的研究仍不充分,无法治疗。CNBP/CPPS的诊断很可能掩盖了许多不同的情况,包括前列腺仅间接或完全不参与病理过程的情况。一些因素,如阴部神经病变伴慢性前列腺炎、CPPB、膀胱梗阻和神经自主神经紊乱,可能同时是病因和发病。尽管目前使用的治疗方法多种多样,但CNBP治疗的问题仍未得到解决。治疗方法通常只针对改善患者的生活质量。所有现有的治疗慢性前列腺炎的方法都暗示着降低性功能障碍水平也是一个理想的结果。改善治疗效果的希望与这些疾病的诊断和鉴别诊断的进展,与疾病临床分类的完善和详细阐述,以及在明确的患者群体中表征药物疗效和安全性的有效临床结果的积累有关。

Method of quantitative evaluation of the immature germ cells, their pathology in mitosis and meiosis (in semen, embryo and fetal ovaries, of gonad biopsies or fragments of sectioned material) is informative method and should be introduced into the clinical practice in andrology and gynecology and fundamental research. Quantitative analysis of mitosis and female meiosis development was initiated on experimental animals and fetal gonads from spontaneous or therapeutic abortions.
定量评价未成熟生殖细胞及其在有丝分裂和减数分裂(精液、胚胎和胎儿卵巢、性腺活检或切片材料片段)中的病理学的方法是一种信息性的方法,应被引入男科、妇科的临床实践和基础研究中。对自然流产和治疗性流产的实验动物和胎儿性腺进行了有丝分裂和雌性减数分裂发育的定量分析。
