Aim: to evaluate the possibilities and efficiency of using 3D technologies for the laparoscopic interventions in patients with renal and ureteric stones. Materials and methods. A retrospective analysis of the results of surgical treatment of patients with renal and ureteric stones performed in the urology clinic of the I.M. Sechenov First Moscow State Medical University of Minzdrav of Russia for the period from January 2012 to December 2017 was carried out. During this period a total of 4958 interventions were done. Among them, 98 laparoscopic (1.97%) surgeries were performed, including nephron-sparing interventions (n=47; 48%), pyelolithotomy (n=15; 15.3%), ureterolithotomy (n=32; 32.65%) and partial nephrectomy (n=4; 4.05 %). The average patients’ age was 55.76±10.5 (29-80) years. There were 51 men (52%) and 47 women (48%). The mean stone density was 1237.6±354.6 HU (from 500 to 1913 HU). In 14 (22.9%) cases, nephrostomy tube or ureteric stent had been put before surgery. In addition, 40 (40.8%) patients previously underwent one surgical intervention on the kidneys and 17 patients with urinary stone disease (17.3%) underwent surgery ≥ 2 times. 88 (89.8%) patients had severe concomitant diseases and the most common pathology in 51 (52.0%) patients with urinary stone disease was arterial hypertension. In 11 (11.2%) cases, the interventions were performed in patients with abnormal kidneys, including horseshoe kidney (n=6; 6.1%), duplicated collecting system (n=3; 3.1%) and pelvic kidney (n=2; 2%). In addition to standard preoperative diagnostic methods in 22 cases (22.4%) the 3D-planning and multivariate virtual performing of intervention based on the multidetector computer tomography scan was done using Amira 3D-modeling program. Among these patients, virtual interventions were performed prior to all pyelolithotomy and partial nephrectomy. Intraoperative data of virtual constructions were used by surgeons as navigation. The interventions were performed by seven urologists at the clinic with various experience in laparoscopic surgery. Results. The mean duration of laparoscopic pyelolithotomy, laparoscopic partial nephrectomy, laparoscopic ureterolithotomy and laparoscopic nephrectomy was 183.2±69.6, 201.3±35.2 min, 97.6±43.7 and 165.4±92.3 min, respectively. The minimal blood loss was observed during laparoscopic ureterolithotomy (53.33+31.2 ml). During these interventions, in 8 cases (8.16%) a flexible endoscope was used for inspection and complete removal of stones. Intraoperative complications were noted in 6 patients (6.1%). There were 4 conversions to open surgery (4.1%). Postoperative surgical complications were observed in 1 (1%) patient, while non-surgical complications developed in 4 patients (4.1%). There was no mortality. Conclusion. Laparoscopic access for the treatment of patients with urinary stone disease should be used for the treatment of patients with large, long-standing ureteral calculi and patients with kidney stones who have concomitant pathology of kidney or upper urinary tract (UPJ obstruction, kidney tumors) requiring surgical intervention. Laparoscopic access should be considered primarily for the planning of laparoscopic partial nephrectomy and laparoscopic nephrectomy in patients with urinary stone disease. The use of 3D computer-assisted technologies is advisable for patients with urinary stone disease and abnormal kidneys if laparoscopic pyelolithotomy, partial nephrectomy or ureterolithotomy is planned

Aim. To evaluate the efficacy and safety of the antibacterial drug fosfomycin trometamol (Fosfomycin Esparma) in women of reproductive age with acute uncomplicated cystitis. Materials and methods. In order to assess the efficacy and safety of using fosfomycin trometamol (Fosfomycin Esparma), a prospective, non-randomized, uncontrolled study involving 32 women with acute uncomplicated cystitis was carried out. The average patients’ age was 27.3±3.1 years. Before the study, all women underwent a general clinical, bacteriological, and ultrasound examination. Inclusion criteria was the presence of pathognomonic symptoms of acute uncomplicated cystitis. Exclusion criteria were as following: complicated urinary tract infection, anatomical and functional disorders of the urinary tract, comorbidities. All patients were prescribed a study drug at a dose of 3 g, once. The efficiency of therapy was evaluated on days 3 and 14 after administration of Fosfomycin Esparma based on clinical and microbiological cure and safety. Results. The only bacterial pathogen isolated from the urine was E. coli. In 4 cases (12.5%) strains produced extended-spectrum β-lactamase. The sensitivity of E. coli to fosfomycin, piperacilfin/tazobactam, amikacin and meropenem was 100%. A resistance to ampicillin was 15.6%, compared to 9.4% for levofloxacin and norfloxacin and 12% for cefotaxime, ceftazidime, cefpoxin. By the 3rd day after receiving fosfomycin, the symptoms of cystitis were resolved in all patients. On day 14, according to the results of the urine culture, there was no growth of bacteria. During the follow-up period, no significant side effects was detected. Conclusion. Our study showed that antibacterial drug Fosfomycin Esparma in women of reproductive age with acute uncomplicated cystitis is effective and safe. Maintaining a high sensitivity to fosfomycin allows us to recommend this drug as an empirical antibiotic therapy in this cohort of patients.

To date, descension of the pelvic floor is a fairly common gynecological pathology that requires surgical treatment. The development of cellular technologies suggests that the use of multipotent mesenchymal stem cells (MMSC) in the treatment of this pathology can stimulate the regeneration of damaged tissue and contribute to the reconstruction of the structures of the pelvic floor. Objective: to evaluate the effectiveness of using MMSC in combination with biological and synthetic materials in vitro and in vivo with descension of the pelvic floor. Materials and methods: Sprague Dawley rats 10 weeks old weighing 200 grams were used in the experiment. Under sterile conditions, mechanical damage to the posterior wall of the vagina was carried out, with the restoration of which vicryl 3-0 was used. On the 2nd and 4th day, the wound was cut off in a volume of 1.5 ml with xenograft, allograft and multipotent mesenchymal stem cells (MMSC) (5 thousand cells) obtained from the adipose tissue of rats. In the control group was not used biological material. At the second stage of the experiment, the compatibility of the mesh prosthesis with MMSC and allograft in vitro was evaluated. Results and discussion: xenograft does not lead to full tissue regeneration, but contributes to rapid epithelialization and reduces the degree of inflammatory reaction in the wound during the regeneration of connective tissue. The use of allograft leads to quick and complete epithelialization of the wound and the formation of a structurally complete connective tissue lamina of the vaginal mucosa. The introduction of MMSC resulted in complete epithelialization of the wound and the formation of a structurally complete connective tissue plate of the mucosa and submucosa, but with a slightly smaller number of blood vessels in them than with the use of a biomaterial. At the second stage of the experiment, weak cell adhesion to the polypropylene substrate of the tablet was observed during cell culture in the presence of only a fragment of the mesh prosthesis. After MMSC cultivation in the presence of a mesh prosthesis fragment and an allograft, a relatively uniform distribution of cells around the mesh prosthesis loops was observed. Conclusions: it was determined that the use of MMSC and allograft has a positive effect on the process of vaginal tissue regeneration in rats. When combining these materials with mesh prostheses, it was found that MMSCs are not fixed directly to the synthetic material, but when the allograft is added, they concentrate and presumably have the maximum anti-inflammatory effect and promote tissue regeneration at the site of the mesh prosthesis. Thus, the use of autologous MMSC cells in combination with allograft and mesh polymeric materials for pelvic floor reconstruction can significantly improve the results of reconstructive operations.

Aim: to improve the results of radical cystectomy by optimization of patient preparation for surgery and early postoperative care. Materials and methods. A total of 136 patients who underwent radical cystectomy and either orthotopic ileal neobladder or ileal conduit formation were included in the study. Brikker’s operation was performed in 92 patients (76% men and 24% women) aged from 39 to 83 years, while in 44 patients (97.7% men, 2.3% women) aged from 32 to 75 years the Studer ileal neobladder was created. All patients underwent preoperative comprehensive examinations in order to determine type and extent of surgical treatment. Results: A complication rate after radical cystectomy with urine derivation using bowel segment was 49.2%. Mortality rate in early postoperative period was 3.9%. Conclusion: An algorithm of postoperative care after radical cystectomy with formation of either orthotopic neobladder or ileal conduit and consideration of comorbid status and preparation which we have used in clinical practice was developed. According to the results, after implementation of algorithm of management in preoperative and early postoperative period a decrease in complications and mortality rate has been found.

Aim: to compare the efficiency of monotherapy with α-blockers vs combined therapy (а-blockers in combination with Androgel) in patients with BPH and hypogonadism. Materials and methods: a total of 60 men with BPH and hypogonadism, who were randomly selected from outpatient department were included in the study. All patients were divided into 2 groups (n=30). In Group 1 patients received silodosin, while in Group 2 men were prescribed to silodosin plus Androgel 1% topically. The duration of therapy was 6 months. The results of treatment were evaluated during baseline assessment and further visits every 2 months after starting therapy (total 4 time points). Results: according to the ICEF-5 questionnaire, in the Group 2 an improvement in sexual function domain score (from 6.3 to 26.8 points) was shown. In addition, in combination group there were significant changes in PSA level (from 2.25 to 1.8 ng/ml), prostate volume (from 55.1 to 61.3 cm3), residual urine volume (from 72 to 19 ml), urine flow rate (from 13.34 to 21.1 ml/s), waist circumference (from 116 to 103.2 cm) and body mass index (from 35.4 to 27.2 kg/m2), while in monotherapy group none of these indicators significantly improved. Conclusions: the use of topical hormone replacement therapy in combination with α-blockers in patients with BPH and concomitant hypogonadism is justified and effective in comparison with monotherapy with α-blockers.

The causes of male infertility remain unclear in 30-75% cases and are considered idiopathic. The study of influence of free oxygen radicals on the male reproductive function is of outmost interest. Given the important role of hyaluronidase in the penetration of sperm into the egg, we decided to evaluate the drug Longidaza, which has long-acting enzymatic (proteolytic) activity. A total of 48 men with idiopathic infertility were included in the study. All patients were divided into two groups (24 men each). In Group 1 there was a recommendation to attempt to conceive for 1 year without additional treatment. In Group 2, patients were prescribed Longidaza according to the proposed scheme. During the follow-up, there was a significant improvement in the antioxidant defense system of the ejaculate in Group 2, which was accompanied by an increase in the fertilizing ability of the ejaculate and an increase in number of conceptions by 29.1%

Purpose. To evaluate erectile function in patients with Peyronie’s disease (PD) who underwent corporoplasty. Materials and methods. A total of 374 patients who underwent corporoplasty by a single surgeon during 1996-2016 were analyzed. In all cases IIEF questionnaire was evaluated pre- and postoperatively. Intracavernous injection test and penile doppler ultrasonography were performed if required. Median follow-up was 9.5 years. Analysis of risk factors for erectile dysfunction (ED) before and after corporoplasty was performed. Results. Prevalence of risk factors for ED in our sample has greatly increased during follow-up. At the last follow-up visit 285 patients were sexually active. Evaluation of patient satisfaction with the quality of erections has shown that 139 patients were fully satisfied (48.8%), 84 patients were somewhat satisfied (29.5%) and 62 patients were not satisfied with their erectile function (21.7%). According to IIEF questionnaire, 105 patients (36.8%) had no ED (> 26 points); 74 patients (26%) had mild ED; 67 patients (23.5%) had mild-to-moderate ED; 21 patients (7.4%) had moderate ED; and 18 patients (6.3%) had severe ED. However, a causal relationship between ED and treatment of Peyronie's disease was found not in all cases. Seven patients had infrequent sexual intercourse (1-2 per month) and 50 patients had no sexual activity. Discussion. At long term after corporoplasty some patients experience ED, though causality between ED and PD treatment couldn’t be confirmed in all such cases. It should be noted that we have found an increase in prevalence of independent risk factors for ED during follow-up period. These patients could possibly benefit in terms of quality of life if they underwent penile prosthesis placement during primary surgical treatment for PD. However, some patients had no sexual activity due to causes unrelated to ED. Conclusion. Not all patients with PD are satisfied with their sexual functioning after corporoplasty. However, ED after surgical management of PD is not always a consequence of surgery itself.

The presented clinical case of a girl with a salt-wasting form of congenital adrenal hyperplasia in combination with chronic recurrent infection and lower urinary tract dysfunction demonstrates the need to change conventional two-staged approach to surgical feminization in favor of a one-stage intervention in order to prevent a progression of genitourinary complications. After controlling for the underlying condition, the one-stage feminization was performed, including modified tightening introitoplasty using a Passerini-Glazel flap and a correction of hypertrophic clitoris and labia minora. Good short- and long-term results were achieved.

Ectopic of the ureter into the cervix is a rare case in the clinical practice of pediatric urologists around the world. This paper presents an observation of congenital urinary incontinence in a 13-year-old girl who underwent an annual examination in a hospital at the place of residence.

This review is dedicated to orgasmic function which is one of the most intimate and crucial aspects of quality of life in patients who underwent radical prostatectomy for prostate cancer. The main risk factors that affect orgasmic function and recovery period after surgery are described.

This literature review is dedicated to urethritis which is one of the most common disorders of urogenital tract in men. The current views in its etiology as well as problems in diagnosis with the main being the frequent inability to isolate etiological factor of inflammation it the urethra are described. The analysis of literature suggests a possible role of bacteria, which are associated with bacterial vaginosis in women, in the development of the urethritis in men. However, the frequency of such urethritis and causative role of specific pathogens has not been studied yet. Meanwhile, the exact determination of the causes of inflammation has direct influence on the choice of appropriate etiologic treatment and can increase its efficiency.

The review analyzes the results of using non-transecting anastomotic urethroplasty in men with urethral strictures. Identified 14 original studies using this technique: 13 foreign and 1 Russian. In total, this technique was applied in 704 patients. This technique was used in 85% of cases with bulbar urethral stricture, in 15% - with posterior stricture. The average length of the urethral stricture in all studies was less than 2 cm, except for two works, where the average stricture length was 2.3 cm and 3.9 cm, respectively. This technique is equally successfully applied in all etiological variants of urethral stricture. The incidence of postoperative complications in all studies using non-transecting anastomotic urethroplastyaveraged 13.7%. Postoperative complications were mostly mild and corresponded to G1 according to Clavien-Dindo classification.According to 10 out of 14 studies that evaluated the effect of surgical treatment on the occurrence of erectile dysfunction (ED), the incidence of ED de novo was on average 13.4%. The success of treatment with the use of non-transecting anastomotic urethroplastyaveraged 95% (82-100%) with a median postoperative follow-up of 27 months (6-64 months). In 4 out of 14 studies, an additional comparison was transecting versus non-transecting techniques. Non-transecting technique was not inferior to transecting technique by any criterion, but, on the contrary, exceeded it in a number of indicators, including the dynamics of sexual function after surgery.On the basis of available studies on the use of non-transecting anastomotic urethroplasty, this technique should be recognized as a highly efficient and reasonably safe method for treating short urethral strictures and recommended for widespread clinical use.

In recent years, the quality of germinal cells has been recognized as the main factor determining reproductive potential. Standard sperm analysis is of limited value for predicting both the achievement of a pregnancy and the outcomes of assisted reproductive technologies, which raises the question of the additional significance of functional testing. Most current guidelines recommend to perform additional studies from a scientific point of view, recognizing their importance, but don’t include men in the basic diagnostic schemes. In this review, we try to discuss of the relevance of special sperm testing.

In clinical practice, urologist often has to treat women who have various forms of dysuria that do not have a pathomorphological substrate and manifest by various types of urinary disturbances and pathological sensations in the urinary tract. The relevance of this topic can be explained by the increasing prevalence of dysuria, its recurrent nature and insufficient efficiency of routine urotherapy, including the use of an extensive armamentarium of drugs and interventions, as well as by pronounced discomfort and a significant decrease in the quality of life and working capacity in the socially active adult patients. Despite a steady growing of interest in this problem, most researchers use a variety of questionnaires and evaluation methods and receive extremely unreliable data that do not contribute to an understanding of the serious psychourological problem of a particular patient with dysuria. In this article, such cases are discussed from the perspective of an interdisciplinary approach using the qualification apparatus of modern psychosomatic medicine and relying on the clinical experience of leading specialists in the field of urology and psychosomatics. The introduction of a comprehensive multidisciplinary approach into clinical practice will contribute to adequate referring, timely provision of specialized care, a reduction of medical costs and an increase in the quality of life in a large group of patients with dysuria.
