Introduction. Bladder neck stenosis (BNS) is a late complication of surgical treatment for benign prostatic hyperplasia. Available methods of endoscopic correction in primary BNS have limited effectiveness, while in recurrent cases their use does not lead to satisfactory results at all. YV-plasty of the bladder neck (BN) is one of the available methods of treatment for recurrent BNS.Purpose of the study. To evaluate the treatment results of patients with recurrent BNS using endovideoscopic YV-plasty of the BN.Materials and methods. We retrospectively analyzed the treatment results of 8 patients with recurrent BNS who underwent endovideoscopic YV-plasty of the BN in the Urology Division No.1 of the St. Luke St. Petersburg Clinical Hospital from 2019 to 2021.Results. Endovideoscopic YV-plasty of the bladder neck was successfully performed in all 8 patients. The mean preoperative Qmax was 3.7 ml/s (1.8 – 5.7). At 6 months after surgery, the mean Qmax was 21.4 mL/s (16.7 – 24.1). The mean preoperative I-PSS score was 20.5 (17 – 24). The mean I-PSS score 6 months after surgery was 7.1 (5.0 – 9.0). No cases of de-novo stress urinary incontinence were registered.Conclusions. Endovideoscopic YV-plasty of the BN may be an effective and safe method of treatment of patients with recurrent BNS. However, further studies are needed to obtain long-term results.

Prostate cancer (PCa) is a public health problem worldwide. Among all malignant tumors, PCa ranks second in prevalence (105 out of 185 countries) and fifth in cause of death in men in 46 countries. In some cases, this pathology is verified in men under the age of 50, including the advanced stage of the metastatic process. The review article provides information on the epidemiology and prevalence of PCa in young men obtained from the PubMed, CrossRef, and Scopus databases. The data on the probable causal relationship of a number of factors potentially affecting the development of prostate carcinoma are presented. Little-known and new molecular genetic changes are described, including those associated with prostate-specific antigen (PSA), with a proven role in the development of this disease, the use of which will make it possible to predict PCa development in the early stages in a timely manner. It has been determined that the common methods for diagnosing carcinoma in the population, assessing the level of serum PSA, are not always accurate and that the algorithm for their use has not been finally formed. The study of risk factors for the development of PCa in young patients will make it possible to formulate a new diagnostic approach based on considering personal molecular genetic information. The development of this direction is relevant and has an important social and economic importance, considering the study of the contingent of the able-bodied population.

Introduction. Transvaginal mesh-reconstruction of urogenital prolapse remains a controversial trend in modern urogynecology. We have seen growth in transvaginal mesh surgery since 2004, followed by a sharp decline after 2011 due to FDA restrictions related to imperfections in previously available prostheses and implantation techniques. Improving the efficacy and minimizing complications of transvaginal mesh-surgery is at the forefront of research in the field of modern urogynecology.Purpose of the study. To optimize the indications for transvaginal mesh-reconstruction of anterior apical prolapse.Materials and methods. The study enrolled 375 patients with anterior apical prolapse. The grade of prolapse was assessed using POP-Q. In patients with endopelvic pelvic fascia insufficiency, severe cystocele (Aa ≥ +1) and hysteroptosis grade II – IV, the correction was carried out using the six-arm OPUR® («ABISS», Saint-Étienne, France). lightweight polypropylene monofilament implant (n = 290). When the cystocele was not prominent (Aa ≤ -1) and grade III – IV hysteroptosis, posterior sacrospinal hysteropexy was preferred with the CYRENE® («ABISS», Saint-Étienne, France) tape (n = 85). In 35 patients, the operation was combined with anterior colporrhaphy. In 5 patients, a simultaneous conization/amputation of the cervix was performed. The examination was performed 1 month after surgery and then annually. Prolapse ≥ grade II was as recurrent. The follow-up period of 67 patients was more than 4 years.Results. After OPUR® prosthesis implantation, recurrent hysteroptosis was detected in 6 women with cervical hypertrophy / elongation within a period of 1 mo to 3.5 yr and cystocele in 4 patients. The efficacy was 96%. In 9 patients, an postoperative ischuria was found associated with extensive dissection and hypotension of the bladder wall due to chronic urinary retention in severe cystocele. Urination improved in 88% of cases. In the remaining cases, long-term mediator and hormone replacement therapy were continued., One recurrent hysteroptosis was observed during the implantation of the CYRENE® prosthesis. No damage to the bladder was observed. Acute urinary retention was detected in 1 case, which resolved after intermittent catheterization. Conclusion. The availability of 2 types of transvaginal prostheses for various degrees and configurations of urogenital prolapses allows a differentiated approach to their choice. Both prostheses suggest reliable «reconstruction-imitation» of the sacroiliac ligament by sacrospinal hysteropexy. If necessary, the operation can be supplemented with anterior colporrhaphy. The prevalence of anterior prolapse with endopelvic fascia insufficiency requires more extensive reconstruction, which can be performed relatively safely and effectively by implantation of a 6-arm OPUR® prosthesis.

Introduction. Currently, the most common method of treating extended urethral strictures is augmentation urethroplasty using oral mucosa grafts. Analysis of the long-term outcomes of this surgery type shows a high incidence of relapses and complications.Purpose of the study. To improve the outcomes of augmentation urethroplasty, in particular the dorsal inlay (Asopa) technique, in patients with extended spongy urethral strictures by minimizing the risk of recurrent strictures.Materials and methods. The study is based on an analysis of the surgery in 90 patients (aged 18-72 years) with extended spongy urethral strictures. Seventy patients (group I) underwent dorsal inlay augmentation urethroplasty according to the Asopa technique, and 20 patients (group II) — according to the author's modified technique. Statistical data analysis was carried out using the SPSS ver.26 software (SPSS Inc. Chicago, IL, USA).Results. A comparative analysis of the course of the early postoperative period showed a lower number of complications in group II patients compared to group I — 20.0% versus 34.3%, respectively. The recurrent strictures were registered for groups I and II in 18.8% and 5.6% of cases 6 months after surgery, respectively. The recurrent urethral narrowing was most often localized in the area of distal anastomosis between the buccal graft and the native urethra in patients from both groups.Conclusion. The modified dorsal inlay augmentation urethroplasty technique developed and implemented in clinical practice by increasing the internal urethral lumen in the areas of proximal and distal anastomosis between the buccal graft and the native spongy urethral body allows minimizing the risks of recurrent urethral narrowing after augmentation urethroplasty.

Introduction. Lower urinary tract symptoms (LUTS) are common in men and are associated with a significant decrease in quality of life. To date, there is no universal approach to the treatment of LUTS, which determines the need to search for new methods for influencing the lower urinary tract.Purpose of the study. To test the hypothesis that the use of peripheral magnetic neuromodulation (PMN) in male patients with LUTS will reduce the severity of LUTS.Materials and methods. Sixty-eight men with LUTS were enrolled in a prospective, randomized study. Patients were randomized in a 1:1 ratio for PMN or drug therapy with an alpha-1-blocker (tamsulosin). The primary endpoint was a reduction the LUTS severity such as urinary frequency during the day, nocturia and urgency as assessed using the IPSS questionnaire and urination diary. Improvements in urodynamic parameters such as maximum urine flow rate (Q max), mean urine flow rate (Q ave), and residual urine volume (PVR) were the secondary endpoint of the study. The results were evaluated on equal terms (10 days and 1 month) in both groups.Results. Sixty-seven (98.5%) subjects were included in the final base. Ten days after the start of therapy in the magnetic stimulation group, symptom relief was noted by 21 people (61.7%), the mean IPSS score showed a decrease from 18.1 ± 2.1 to 16.9 ± 3.2 points (p = 0.037). The number of urinations per day decreased from 14 (6 - 20) to 10 (6 - 14) times (p < 0.001). Objective indicators of urodynamics did not change in both groups. At a period of 1 month, PMN occurred in 22 (64.7%) patients, the IPSS score was 16.6 ± 3.7 points (p = 0.032), the number of urinations 9 (6 - 14) times (p < 0.001). Objective indicators have not changed. In the tamsulosin group, IPSS score changed from 19.27 ± 5.08 to 15.4 ± 4.85 (p < 0.001), Q max 14.36 ± 2.82 ml/s increased to 15.94 ± 2.71 ml/s (p = 0.032), while the Q ave did not change (p = 0.17). The number of urinations decreased from 13 (6 - 19) times to 10 (6 - 14) times (p <0.001).Conclusion. The study demonstrated the promise of PMN in men with LUTS in terms of improving the quality of life. The proposed method may be preferable for patients dissatisfied with drug therapy. Further placebo-controlled studies are required to help determine the role of PMN in the management of patients with LUTS.

Introduction. According to the literature, 5.0% of patients with urolithiasis are characterized by the presence of stones in the bladder. The issue of bladder stones for patients with benign prostatic hyperplasia remains relevant and requires further improvement of approaches to surgical treatment.Purpose of the study. To evaluate the safety and efficacy of energy-diverse percutaneous cystolithotripsy (and placement of a cystostomy catheter) in comparison with transurethral cystolithotripsy.Materials and methods. A retrospective analysis of 56 cases in patients (aged 54-82 years) with bladder stones was carried out. All patients were treated in the Urology Clinic of the Mechnikov North-Western State Medical University from 2019 to 2021. Two groups were formed: group I — 26 (46.4%) patients who underwent percutaneous cystolithotripsy, group II — 30 (53.6%) patients underwent transurethral cystolithotripsy. The duration of surgery, intraoperative and postoperative complications were assessed.Results. On average, the duration of surgery for the percutaneous approach was shorter than for transurethral access (35 vs 44 min). The stone-free rate in the case of the percutaneous approach was 100.0%, while in transurethral cystolithotripsy the stone-free rate was 90.0%. In the early postoperative period, in groups I and II, gross hematuria was observed for 2 (7.6%) and 4 (13.3%) patients, respectively. In the late postoperative period, 2 patients from group II had a urethral stricture.Conclusions. Percutaneous cystolithotripsy is a minimally invasive method of stone fragmentation, characterized by a minimal risk of intra- and postoperative complications.

Introduction. According to the results of numerous studies and meta-analyses, the effectiveness of male infertility therapy with micronutrients-antioxidants in various variants remains low, especially concerning the increase in live-birth rates and the incidence of clinical pregnancy. This may be due to both the empirical nature of such therapy with an imbalance of ejaculate redox systems, and an overdose of individual ingredients of antioxidant complexes.Purpose of the study. To evaluate the antioxidant activity of complex preparation based on L-carnitine for the treatment of male infertility in an experimental model system.Materials and methods. The dietary supplements «AndroDoz®» («Nizhfarm» JSC, Russian Federation) and «Proxeed® plus» (Sigma-Tau Pharmaceuticals Inc., Italy) were tested. The antioxidant properties of the preparations were determined in vitro by recording chemiluminescence in model systems generating reactive oxygen species using the «LKB-Wallac 1256 chemiluminometer» (Wallac Oy/PerkinElmer®, Finland). Chemiluminescence was evaluated by the light sum and the maximum amplitude of the glow, the antioxidant activity in the biological environment was studied when adding drugs to chicken yolk lipids similar to blood lipoprotein complexes.Results. The introduction of «AndroDoz®» and «Proxeed® plus» into the incubation medium in an amount comparable to the physiological level of L-carnitine in seminal plasma, inhibited the luminescence of the model system. At the same time, if «Proxeed® plus» almost completely inhibited the formation of radicals, then an equivalent dose of «AndroDoz®» reduced the intensity of chemiluminescence by 60%. Approximately in the same proportions, the preparations suppressed the intensity of lipid peroxidation processes in a model system with lipoprotein complexes similar to blood lipids, that is, the antioxidant activity was preserved in the biological environment. A decrease in the value of the chemiluminescence light sum was also found against the background of the use of these dietary supplements, which may indicate their protective effect on biological membranes, including subcellular structures of spermatozoa.Conclusion. The combined dietary supplements used in the study have a high antioxidant potential. The preparation «Proxeed® plus» can completely suppress the processes of lipoperoxidation with the possible development of a deficiency of free radicals that provide vital processes. The preparation «AndroDoz®» has a milder effect on free-radical phenomena probably due to a lower content of active ingredients and a balanced composition, which reduces the risk of complications in the form of an «antioxidant paradox» or reductive stress.

The clinical case represents the surgical correction of postoperative complications in a patient with Peyronie's disease. The patient underwent flap corporoplasty using an autovein. The late postoperative period in the patient was complicated by extensive necrosis of the penile skin, which required repeated surgery as follows. The first stage of surgical treatment was performed by excision of necrotic tissues of the penile skin. Within 10 days of the postoperative period, chymotrypsin with an ointment containing dioxomethyltetrahydropyrimidine with chloramphenicol was applied to the penile wound surface to prepare the wound for subsequent skin autotransplantation. Further, within 5 days, the polymeric drainage sorbent «Aseptisorb DT» was applied to the wound surface until the wound was cleansed and granulation tissue was formed. The second stage of the surgical treatment performed penile skin replacement plasty with a free perforated skin graft taken from the patient's femoral surface.
