The literature periodically calls for systematization terms used in describing the position undescended testis. Due to the confusion in terminology, it is difficult to generalize and analyze the data obtained. The same position of the undescended testis is described differently by various authors, which led to the appearance of many authors' cryptorchidism classifications at the beginning of the 21st century. This review of the literature states the fact that, over time, no consensus has been found regarding the classification of undescended testicles. Currently, there is a need to generalize the available data to select the optimal treatment algorithm. If the treatment algorithm for the palpable testicles is well studied, then the choice of a treatment method for the cryptorchidism non-palpable forms remains debated in the surgical community.","PeriodicalId":345779,"journal":{"name":"Vestnik Urologii","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129125592","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}

According to the WHO data, depression is a common disease among women and men of reproductive age. One line of the correction of depressive disorders is selective serotonin reuptake inhibitors (SSRIs). The ingestions have shown that using SSRIs harms sperm quality.

To evaluate the influence of Fluoxetine intake on semen parameters, sperm DNA fragmentation and hormonal status.Materials and methods. Twenty-five men (mean age - 35.2 ± 4.5 yo) with depression were included in the study. Fluoxetine (20 mg per day) was prescribed to all the patients for 12 wk. Semen parameters, sperm DNA fragmentation, sex hormones levels were measured before-after treatment and 3 mo behind discontinuation.Results. After 12 weeks of the treatment the mean semen volume decreased from 3.1 ± 0.7 to 2.9 ± 0.7 ml (p = 0.638), sperm concentration - from 39.4 ± 18.5 to 34.3 ± 16.8 mln/ml (p = 0.384), sperm motility decreased from 41.7 ± 7.6 to 35.5 ± 7.8% (p < 0.05), the mean percent of normal morphology form - from с 12.7 ± 2.8 to 10.7 ± 2.2% (p < 0.001).

Extrapulmonary tuberculosis (EPTB) still has many features: there is a different approach to its definition in different countries, there is no screening, diagnosis is extremely difficult and requires financial costs, and bacteriological verification does not exceed 46%, complex restorative and reconstructive operations are used in treatment. the proportion of patients with isolated extrapulmonary localizations among tuberculosis patients is low.Purpose of the study. To study the structure of tuberculosis (TB) in children with the accentuation of EPTB in the current conditions to determine the development areas of preventive and diagnostic measures.Materials and methods. A retrospective two-stage study was carried out in the period from 1989 to 2018 among in-patient children aged 0 - 14 yrs. At the first stage, the structure of clinical forms of TB was assessed in 2306 children. Three comparison groups were formed following ten-year periods. At the second stage, 4 groups were identified according to age: early age, preschool age, primary school age, prepubertal age. The data obtained in the course of the study were statistically processed using the Microsoft Office 2007 (Microsoft Corp., USA) and Biostat 2009 (AnalystSoft Inc., USA) software package. The differences between the groups were determined using the χ2 test, and significant differences were considered when the value of the p < 0.05 criterion.Results. It was found that throughout the entire observation period in the region, the predominant localization of the specific process was respiratory TB. The proportion of isolated extrapulmonary lesions in children decreased from 11.1% in the period from 1999 to 2008 to 3.4% in the period from 2009 to 2018 (p = 0.000). At the same time, the most frequent localization (60.4 - 77.8% of cases) among EPTB remains urinary TB. In the dynamics from 1989 to 2018, the number of cases of the disease with combined forms of tuberculosis increased (from 3.1% to 7.2%; p = 0.000), mainly due to the establishment of several localizations of the lesion. The frequency of bacteriological confirmation of the diagnosis was significantly different at various localizations of the specific process. In children of the compared periods of childhood, the predominant localization of the specific process was isolated respiratory TB. The isolated extrapulmonary process localizations were more common in the age groups 7 - 11 and 12 - 14 yo, where it accounted for 10.8 - 12.4% of TB cases (p = 0.000). The localization of the EPTB also depended on the children's age. So, young children often developed damage to the osteoarticular system, in preschool children - the genitourinary and lymphatic (peripheral lymphadenopathy) systems, in younger schoolchildren and preschoolers - the genitourinary system.

Urethroplasty is the “gold standard” treatment of urethral stenosis. However, often in connection with old and senile age, as well as due to the presence of concomitant diseases, it is not possible to carry out urethroplasty due to its certain invasiveness. In such cases, one of the methods of treatment is the installation of a urethral stent. But this method has not found practical application due to the frequent migration of stent and the high frequency of its incrustation. The approach developed by us avoids stent migration.Purpose of the study. To evaluate the immediate results of the placement of a urethral stent with fixation through the perineum.Materials and methods. A total of 18 patients with urethral stenosis aged 68 to 84 years have been operated on since February 2019. Ten patients had stenosis of the urethrocystoneoanastomosis after radical prostatectomy, 6 patients had iatrogenic stenosis of the prostatic urethra, 1 patient had post-radiation stenosis of the bulbo-membranous urethra. All patients in the preoperative and postoperative periods underwent: IPSS-QoL questioning, uroflowmetry, bladder ultrasound with residual urine volume evaluation, urethroscopy, ascending and micturition urethrocystography. The first stage was an internal optical urethrotomy according to the standard technique. Then, a urethral stent was installed in the area of dissected stenosis. The second stage was an incision in the perineum, the urethra was isolated, and under optical control, through the perineum, the stent was fixed to the urethra with non-absorbable suture material. The stent was removed endoscopically after 6 months.Results. The median surgery duration averaged 45 minutes. Patients were discharged 2 to 3 days after surgery. The maximum observation period was 20 months. During the observation period, not a single case of stent migration was recorded. All patients showed a persistent increase in Qmax and no residual urine. Six patients had a stress component of urinary incontinence, 4 patients had total urinary incontinence. According to control urethrocystoscopy 6 months after stent removal, clinically insignificant urethral stenosis was noted in all patients. In all cases, moderate signs of stent encrustation were identified. Dysuric phenomena disturbed 5 patients, who were stopped by rectal suppositories with NSAIDs, as well as taking herbal uroseptics. The data from the IPPS-QoL questionnaires confirm the positive effect of the treatment.Conclusions. Temporary placement of a urethral stent for urethral stenosis is an effective minimally invasive treatment. The technique of fixation through the perineum allows preventing migration in all cases. This approach to treatment significantly improves the quality of life of patients who were contraindicated for urethroplasty for one reason or another. However, the technique requires longer observation and analysis.","PeriodicalId":345779,"journal":{"name":"Vestnik Urologii","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127193567","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}

To evaluate the possibilities and effectiveness of percutaneous antegrade ureterolithotripsy in the treatment of patients with proximal ureteral stones in comparison with transurethral contact ureterolithotripsy.Materials and methods. Twenty-eight patients with urolithiasis were treated, who underwent percutaneous antegrade ureterolithotripsy (PAULT) and 27 patients of the control group, who underwent RULT. All patients included in the study underwent a standard preoperative examination: complete blood count and urine analysis, bacteriological urine culture, biochemical tests, and X-ray research methods.
