[Reconstructive procedures in women with irradiation injuries of urinary tract: change of a paradigm].

Introduction: Radiation therapy is one of the main methods of treating pelvic malignant tumors, which provides good oncological results. Specific features of the pelvic anatomy may result in various radiation injuries of adjacent organs, which are complicated by genitourinary fistulas, post-radiation fibrosis with the formation of hydronephrosis, microcyst, reducing the quality of life.

Aim: To describe the relevance and importance of the correct choice of surgical treatment in patients with post-radiation urinary tract injuries.

[Study of allelic variants of the CYP2D6 and CYP3A genes on the effectiveness and safety of tamsulosin therapy in patients with BPH: results of a pilot study].

Introduction: Tamsulosin is a member of the group of selective 1-adrenoblockers. Tamsulosin monotherapy is the most common first-line option in patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) and can be used regardless on severity of LUTS. The CYP2D6, CYP3A4, and CYP3A5 enzymes are involved in the metabolism of tamsulosin.

Effects of CYP2D6 allelic variants on therapy with tamsulosin in patients with benign prostatic hyperplasia.

Objectives: Tamsulosin is a first-line drug for the treatment of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). Despite its high ratings for efficacy and safety, these parameters may vary due to genetic polymorphisms of CYP2D6 enzyme, which is involved in the metabolism of the drug. This variability may have great impact on the therapy of LUTS associated with BPH and may require an individualized approach to drug selection.

[The influence of alfuzosin monotherapy on the sexual function of patients with benign prostatic hyperplasia in real clinical practice (results of a Russian multicenter study)].

Introduction: The current armamentarium of drugs for lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) is diverse and includes both monotherapy and combination therapy. Indirect and limited direct comparisons have demonstrated that all alpha-1-blockers (a1-ABs) have similar efficacy when used at appropriate doses. Differences in tropism to the prostate of modern 1-ABs are largely responsible for the severity of their side effects, mainly negative influence on sexual function and cardiovascular system.

In some cases, the authors suggest using these data either for screening of tumors or for controlling the cure.

Genes associated with testicular germ cell tumors and testicular dysgenesis in patients with testicular microlithiasis.

Testicular microlithiasis (TM) is one of the symptoms of testicular dysgenesis syndrome (TDS). TM is particularly interesting as an informative marker of testicular germ cell tumors (TGCTs). KIT ligand gene (KITLG), BCL2 antagonist/killer 1 (BAK1), and sprouty RTK signaling antagonist 4 (SPRY4) genes are associated with a high risk of TGCTs, whereas bone morphogenetic protein 7 gene (BMP7), transforming growth factor beta receptor 3 gene (TGFBR3), and homeobox D cluster genes (HOXD) are related to TDS.

The development of these tumors is related to the formation of a pool of male germ cells and gametogenesis.

[10 YEARS' EXPERIENCE IN USING DIRECT URETEROINTESTINAL ANASTOMOSIS IN URINARY INTESTINAL DIVERSION AFTER RADICAL AND SIMPLE CYSTECTOMY].

[COMPARATIVE ANALYSIS OF POSITIVE SURGICAL MARGIN RATES IN PATIENTS UNDERGOING ROBOT- ASSISTED OR RETROPUBIC RADICAL PROSTATECTOMY FOR PROSTATE CANCER].

The issue of comparative evaluation of oncological and functional outcomes of robot-assisted radical prostatectomy (RARP) and radical retropubic prostatectomy (RRP) is widely discussed in the international literature. A key point in studying the oncological efficacy of both techniques is a comparative evaluation of positive surgical margin (PSM) rates as one of the main prognostic factors influencing the further course of prostate cancer. Available data so far are inconsistent, which prompted us to conduct our own research.

[RATIONAL THERAPY FOR RECURRENT INFECTIONS OF THE LOWER URINARY TRACT. THE RESULTS OF A PROSPECTIVE OBSERVATIONAL PROGRAM TO ASSESS THE EFFECTIVENESS AND SAFETY OF CEFORAL®, SOLUTAB®* AND URO-VAKSOM® IN PATIENTS WITH RECURRENT UNCOMPLICATED LOWER URINARY TRACT INFECTIONS (FLORA)].

Remaining generally unchanged, urinary tract infection (UTI) treatment protocols require continuing monitoring due to growing antibiotic resistance and lowered immune status of the majority of patients. The article presents the results of a prospective observational program carried out the Russian Federation in to assess the effectiveness and safety of Ceforal®, Solutab® and Uro-Vaksom® in patients with recurrent uncomplicated lower urinary tract infections (FLORA). The results of the program suggest that Ceforal® Solutab® and Uro-Vaksom® administered as a part of routine clinical practice contribute to a significant reduction in the number of UTI recurrences and have a good safety profile.

Extracapsular extension occurred in 2.

[Features of neurohumoral regulation in children with combined dysfunction of the pelvic organs].

During examination of 165 children aged 5 to 15 years (primarily identified during planned monitoring in Petrozavodsk children's institutions) with dysfunctional urination and encopresis without organic lesion of the central nervous system, autonomic dysfunction syndrome (ADS) was revealed. According to the results of urological examination, which was supplemented with the registration of spontaneous voiding rate and counting the radial pulse, overactive bladder syndrome and insufficient relaxation of the pelvic floor muscles during urination and defecation were detected; relationship between the number of heart rate (as a marker of sympathetic nervous system activity) and the effective volume was identified. It was revealed that the children with ADS in the presence of tachycardia show intermittent decrease of effective amounts of urination, and have residual urine.
