The aim of this review is to analyze current publications and summarize information about the effect of zinc on male fertility and its properties related to sperm quality and successful fertilization.The data presented in the review showed that the coronavirus affects not only the lungs, but also the organs of the urinary system. The new virus causes a mosaic, multi-organ disease with severe consequences after the egg and has a wide organotropism. The role of SARS-CoV-2 in the development of lower urinary tract symptoms (LUTs), which are manifested by frequent, imperative urges, dysuria, nocturia, is not entirely clear. It is assumed that biologically active substances, the activation of which is caused by a virus, play a certain role in the development of SNMP, namely the expression of angiotensin converting enzyme 2 (ACE2), cytokines, activation of toll-like receptor 4 (TLR4), etc. Epigenetic inhibitor An increase in cytokines that are released into the urine and / or expressed in the bladder and the presence of SNMP in patients with coronavirus infection have been called de novo urinary symptoms or COVID-19 associated cystitis (CAC) in the literature. Urinary symptoms de novo or associated cystitis COVID-19 (CAC) develops against the background of a complete lack of data for the presence of a bacterial pathogen in the urine. Despite the unusual manifestation of coronavirus infection, similar mechanisms of damage to urothelial cells in viral and bacterial infections give us the right to think about the use of pathogenetically justified prevention of the development of an inflammatory reaction in the urinary tract, as well as short-and long-term consequences of this disease. For this purpose, it is necessary to recommend drugs that have a multifactorial effect diuretic, anti-adhesive, anti-inflammatory and regulate the local immunity of the bladder mucosa. We assume that against this background, we can expect a decrease in the number of complications from the organs of the urinary system, and more successful rehabilitation of patients with coronavirus infection and in the post-ovarian period. Final conclusions and recommendations will be available after well-planned clinical trials have been conducted.The development and widespread implementation of modern endourological procedures for the treatment of benign prostatic hyperplasia (BPH) has led to a significant reduction in postoperative complications, but these interventions are associated to an increase of bladder neck contracture (BNC) rate. Various data on the frequency, pathogenesis, and risk factors for the development of BNC after endourological interventions are presented in the literature review. The prevalence of BNC after transurethral procedures depending on the type of energy used reaches up to 10%. Risk factors of BNC included the presence of chronic prostatitis and urinary tract infections, as well as small volume BPH. The age, cardiovascular diseases, type 2 diabetes, obesity, and a long-term smoking are considered as additional risk factors. A detailed study of the risk factors for BNC will further minimize BNC rate after transurethral procedures, thus improving the quality of life of patients.Long strictures of the upper third of the ureter are most often recurrent and occur after endourological and reconstructive procedures. The lack of native tissues and an impossibility of substitution by bowel segment in some cases dictates the use of alternative surgical techniques. Our first experience of laparoscopic onlay ureteroplasty using buccal graft for long stricture of the upper third of the ureter is described in the article. The length of the stricture was 6 cm. The operation time was 210 minutes, while blood loss volume was less than 100 ml. The patient did not have any surgical complications. Drains were removed in timely manner. The patient was discharged from the hospital in a satisfactory condition on the 8-th day. The ureteral stent was removed after 4 weeks. Kidney ultrasound was performed on a monthly basis. According to IVU after 4 months, the anastomosis was completely patent. This method can be considered as an alternative to more complex procedures in selected patients.Bilateral nephrolithiasis is one of the most prevalent and severe form of urinary stone disease, that is usually linked with endocrinological disorders. These patients are quite often treated in our clinic. A clinical case of patient with bilateral nephrolithiasis who undergone to bilateral simultaneous retrograde intrarenal surgery is presented.
to evaluate the relationship between the use of energy drinks and the decline in male reproductive function.
The analysis of scientific publications dedicated to the issue was carried out. The results of the study, which involved 60 patients aged 22 to 40 years, are presented. The directions for further scientific search are suggested.
According to our study, there is a correlation between energy drinks consumption and decreased ejaculate quality.
systematic use of energy drinks has a negative impact on male reproductive function.

to evaluate therapeutic activity of oxidized dextran after rectal administration in a modified sulpiride model of benign prostatic hyperplasia in mice.
The therapeutic activity of oxidized dextran was studied in an experimental model of benign prostatic hyperplasia in mice (sulpiride model). All in vivo studies were carried out on 30 male BALB/c mice with an average body weight of 30-35 g.
It was found that rectal administration of a solution of oxidized dextran effectively neutralizes pathomorphological changes in experimental model of benign prostatic hyperplasia. In the group of animals, which received 2% solution of oxidized dextran as treatment, the most prominent therapeutic effect in an experimental model was seen and it was confirmed by a decrease in the bladder detrusor thickness and the normalization of its lumen.

To assess the morphological and functional characteristics of spermatozoa and DNA stability in patients with normal seed parameters and with an ITZ exceeding the threshold value.
85 males were studied for semen quality parameters. The morphological anomalies of head, middle piece, and tail of spermatozoa were estimated and presented in illustrations. Due to results elaborated the index of teratozoospermia was calculated. Then the Comet assay was performed.
It has been found that spermatozoa from patients with high teratozoospermia index possessed decreased motility as compared to ones from patients with low index of teratozoospermia. It was not found any difference in concentration of spermatozoa between groups of males which possess low and high index of teratozoospermia. The spontaneous frequency of DNA damage estimated by means of single cell gel electrophoresis followed by silver staining in spermatozoa from healthy donors did not exceed 3,1+/-0,6. The frequency of DNA damages in sperm of patients with abnormal index of teratozoospermia exceeded 39,6+/-7,4% (p<0,01).
Our results suggest that minor morphological changes in spermatozoa do not affect their motility, while significant morphological abnormalities with ITZ exceeding threshold values are closely associated with impaired DNA stability and dramatically reduce the quality of patients seed.
In the initial assessment of patient fertility the attention should be focused on a comprehensive study of sperm DNA morphology and stability.

To determine the possibility of performing minimally invasive percutaneous nephrolithotomy (PCNL) under ultrasound guidance with the use of X-ray during the access tract formation.
The results of 102 mini-PNL procedures, performed by a single surgeon during the period 2018-2019, were analyzed retrospectively. In the beginning, ureteral catheter Ch5 was put into an ipsilateral ureter. Further, a puncture of the collecting system was performed with an advancement of the guidewire. At the next stage, a dilation of tract was done using X-ray guidance for the safe formation of the working channel, followed by holmium lithotripsy. At the end a nephrostomy or JJ-stent was left.
The mean age of the patients was 53.13+/-12.9, while average BMI was 29.3+/-6.5. In total, there were 44.1% of women. The average stone size was 20.7+/-10.9 mm; 45.1% of stones were left-sided. Staghorn stones accounted for 15.7% of cases and hydronephrosis was found in 18.6% of patients. The time for creating renal access, dilation of . However, this technique also has disadvantages, including longer puncture time in morbidly obese patients without hydronephrosis. With growing experience, the number of unsuccessful kidney punctures decreases, as well as operative time. The use of fluoroscopy during dilatation of the nephrostomy tract allows for preventing additional injuries of the collecting system.Urethral pain syndrome (UPS) is characterized by the occurrence of persistent or recurrent pain in the urethra in the absence of a confirmed infection and other obvious local pathological changes. The study of its pathogenetic aspects is important first of all for understanding the causes of the disease, to prescribe effective treatment, specific recommendations for the prevention and treatment of this disease are also absent. This paper presents the advanced experience of our research group on the study of the urethral state by the in vivo cross-polarization optical coherence tomography (CP OCT) method, and also the results of the microbiota analysis in the urethral tissues. The purpose of the study is to search for the risk factors for UPS and the character of changes in the urethral tissues, using the data of 1) concomitant pathology, 2) structural changes in the urethral wall in UPS in comparison with chronic cystitis of bacterial etiology 3) studying the microbiota of urethral tissues.
The condition of as revealed, which may be a premorbid background and one of the risk factors for the occurrence and maintenance of UPS. Pilot PCR studies of biopsies from the proximal segment of the urethra indicate that low values of bacterial contamination in the majority of patients with UPS do not exclude the possible role of bacteria in the development of the disease in some patients. The CP OCT method used in this study is currently the only one in vivo method of visualization of the urethral mucosa, which provides real-time images of structural changes in the epithelial (atrophy or hyperplasia) and connective tissue (active or latent inflammation with cellular infiltration or fibrosis) layers of the urethra, allowing better understanding of the pathogenesis of the disease and monitoring of therapy.
