The development of a malignant tumor naturally affects renal function. During tumor formation, the renal tissue is destructed either by direct invasion into the parenchyma, or by mechanical change in the renal architecture caused by compression of the renal parenchyma, collecting ducts, tubules, and nephrons. In addition, a tumor can secrete biologically active substances, which have an indirect negative influence the functional state of the organ. Currently, it has been established that kallikrein-kinin and renin-angiotensin-aldosterone systems play an important role in the development of nephropathy of various genesis. At the same time, these systems' role in the development of renal function disorders in the setting of tumor damage has not yet been studied.Purpose of the study. To study changes in the components of the kallikrein-kinin and renin-angiotensin-aldosterone systems in the case of localized kidney cancer.Materials and methods. Forty-five patients diagnosed with T1N0M0 kidney cancer and 13 relatively healthy patients without cancer were examined. The determination of the components of the systems under study was carried out by the kinetic method after chromatography of blood plasma and urine using DEAE-Sephadex A-50 (Amersham Biosciences Corp., Sweden). The indices of angiotensin-1, renin, aldosterone, and cortisol were studied by an indirect method of radioimmunoassay. Statistical processing was carried out using Statistica 8.0 software (StatSoft Inc., IBM Corp., USA) by means of the Student-Fisher test (p < 0.05).Results. The development of kidney cancer is accompanied by a 2.3-fold increase in the activity of kallikrein and other trypsin proteases with a significant deficiency of their inhibitors (p < 0,05). Against this background, there is a 1.3-fold decrease in the cortisol/renin ratio from a 2.9-fold and 2.3-fold increase in the values of the renin/angiotensin-I and cortisol/angiotensin-I interaction ratios, respectively, compared with the normal values of these indicators (p < 0,05).Conclusions. Renal cell carcinoma is accompanied by trespassing of local metabolism with the formation of tubulointerstitial dysfunction and a shift of the proteinase-inhibitory balance towards proteolytic activation.","PeriodicalId":345779,"journal":{"name":"Vestnik Urologii","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133953652","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}

Super-selective prostatic arteries embolization (PAE) is a modern minimally invasive surgical method for the treatment of benign prostatic hyperplasia (BPH). PAE is included in the Russian clinical guidelines for the BPH treatment and approved for use in the United States and European countries.Purpose of the study. To analyze the most common PAE-associated complications and to develop preventive arrangements.Materials and methods. During the period from 2013 to 2020, PAE as the main method of BPH treatment was used in 168 patients with an average age of 69.3 ± 8.1 (53-82) years. All patients underwent two-day antibiotic prophylaxis before the operation and lasted 7-10 days. For catheterization of the prostatic arteries, 2.0-2.8 Fr microcatheters and 4-5 Fr microconductors were used. For embolization, hydrogel microspheres with a diameter of 100-300 µm and 300-500 µm were used, as well as poly polyvinyl alcohol (PVA) microparticles with a diameter of 100-500 µm.Results. Bilateral PAE was successfully performed in 146 cases; unilateral PAE was performed in 22 patients due to anatomical features. Seventeen (10.1%) PAE from the orifice, super-selective PAE was performed in 67 (39.9%) cases, the PErFecTED embolization was performed in 84 (50.0%) patients. The most common complication was acute urinary retention (AUR) in 28 (16.6%) patients: trocar cystostomy was required in 11 (6.5%) patients, AUR was resolved using conservative therapy in 17 (10.2%) patients. In 23 (14.2%) cases, complications associated with unintentional embolization of the anastomoses of the prostate arteries were identified: rectal pain and/or the appearance of blood in the stool in 19 (11.3%) patients, the appearance of trophic ulcers on the glans penis in 5 (2.8%) patients. In addition, several adverse events that were not complications were noted: postembolization syndrome in 50 (29.7%) patients, and worsening of LUTS in 41 (24.4%) patients. Seven (4.1%) patients had acute epididymitis; 4 (2.4%) patients had a hematoma at the puncture site.Conclusion. PAE can cause a limited number of complications. It is necessary to unify the system for reporting PAE complications. Antibiotic prophylaxis is recommended. The use of visualization and X-ray navigation methods make it possible to make the PAE safer. The PErFecTED technique in combination with small particle sizes increases the risk of complications. The surgeon's experience and proficiency in special surgical techniques are essential. The transradial approach is promising, but further observation and an increase in patient samples are required. The question of choosing the optimal embolization drug continues to be relevant.","PeriodicalId":345779,"journal":{"name":"Vestnik Urologii","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128453875","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}

The difference between obstructive and non-obstructive azoospermia with sperm maturation arrest is important for the choice of treatment tactics and adequate counseling of a married couple.Purpose of the study. The study aimed to assess the semen lipid profile in patients with sperm maturation arrest. Materials and methods. Samples of seminal plasma for lipid composition of 24 men with normozoospermia and 64 men with azoospermia were studied. Patients with azoospermia underwent microdissection testicular biopsy followed by the detection of testicular tissue pathology. Lipid extracts were analyzed by liquid chromatography with mass spectrometry. Lipid data were compared with the results of pathomorphological studies.Results. Comparison of two groups revealed a statistically significant concentration differences for 22 lipids detected in positive-ion mode and 11 lipids detected in negative-ion mode. Those lipids mainly belong to the classes hexosylceramides, sphingomyelins and phosphatidylcholines — simple ethers and oxidized lipids. In multivariate analysis, the following lipids were found to be statistically significant predictors of sperm maturation arrest: PC 16: 0_22: 6 lipid (β-coefficient: -0.73; 95% confidence interval (95% CI): -1.42 to -0.27; odds ratio (OR): 0.48; OR CI: 0.24 to 0.76; Wald's test: -2.58; p = 0.01), SM d20: 1/22:2 lipid (β-coefficient 4.96; 95% CI 2.29 to 9.13; OR: 142.31; OR CI: 9.90 to 9.22^103; Wald's test: 2.93; p = 0.003); PG 20:3_22: 6 lipid (β-coefficient 2.52; 95% CI 1.13 to 4.49; OR: 12.37; OR CI: 3.10 to 89.27; Wald's test: 3.02; p = 0.002); PC O- 16: 1/16:0 lipid (β-coefficient 1.96; 95% CI -4.12 to 0.27; OR: 0.14; OR CI: 0.02 to 0.76; Wald's test: -2.05; p = 0.04). The prediction model characteristics of sperm maturation arrest, obtained during cross-validation in the positiveion mode composed: sensitivity 91%, specificity 85%; in negative-ion mode: sensitivity 75%; specificity 81%.Conclusions. Even though early stages of spermatogenesis are equally preserved in both fertile men and men with homogeneous sperm maturation arrest, the semen in the studied group of patients differed in its lipid profile. Patients with non-obstructive azoospermia, associated with meiosis arrest, may have unique lipidomic characteristics of seminal plasma, which in the future will make it possible to differentiate various variants of severe male infertility using non-invasive methods.","PeriodicalId":345779,"journal":{"name":"Vestnik Urologii","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117084176","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}

Modern radiological treatment options for patients with localized prostate cancer (PCa) have several advantages and allow achieving high rates of biochemical control.Purpose of the study. To compare immediate, proximate, and long-term results of low-dose Iodine-125 brachytherapy (I-125 BT) and robotic stereotactic radiotherapy (SBRT) in patients with localized low- and intermediate-risk PCa.Materials and methods. The study included 296 patients with localized low- and intermediate-risk PCa. I-125 BT and SBRT were performed in 208 and 88 patients, respectively. All patients with an intermediate-risk PCa were prescribed neoadjuvant androgen-deprivation therapy (NADT) with luteinizing hormone-releasing hormone analogues (LHRH) for 4-6 months. Only radiation treatment was used for low-risk PCa. As a result, two groups and four subgroups of patients were formed depending on the treatment method. The immediate, proximate, and long-term results of radiation treatment methods were studied in groups and subgroups.Results. No complications were recorded during brachytherapy I-125. Radiation cystitis grade 1 and radiation rectitis grade 1 were diagnosed after SBRT in 16.6% and 4.0% of cases, respectively. In the only I-125 BT subgroup, the PSA level during the year decreased from 8.3 to 1.1 ng/ml, in the SBRT subgroup — from 7.5 to 0.8 ng/ml. In the case of combined treatment, PSA decreased from 1.2 to 0.93 ng/ml and from 4.5 to 0.5 ng/ml, respectively. Changes in prostate volume, residual volume, and urinary quality (I-PSS) were comparable in all subgroups. Five-year cancer-specific survival and overall survival in the group of patients after SBRT was 100%, after I-125 BT — more than 90%.Conclusion. Radiation treatment options for patients with localized PCa are safe. Conducting NADT does not significantly reduce the prostate volume and does not affect the indicators of urodynamics.

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.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.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)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].

To study the diagnostic efficacy of 18F-FDG PET-CT in various chronic inflammatory diseases of kidneys and bladder.Materials and methods. A retrospective study of the results of whole-body 18F-FDG PET-CT in 45 patients was carried out. Patients underwent an investigation at various times after surgical treatment of localized oncology of the anogenital zone at the T1N0M0 stage without the involvement of the genitourinary system. It was found that 24 patients had a history of chronic pyelonephritis and 21 patients had manifestations of radiation cystitis. Repeated PET/CT scans were performed after a course of therapy for inflammatory urological diseases to assess the treatment results of the underlying pathology.Results. The latent course of chronic renal failure was accompanied by a diffuse decrease in 18F-FDG metabolism in the renal parenchyma with its partial recovery after etiotropic therapy and urine sanitation. Hypermetabolism of 18F-FDG was detected in the bladder wall during manifestations of radiation cystitis, which was leveled during therapy and relief of urinary syndrome manifestations.
