[The first experience of clinical use of optical urethral catheter Visus MG].

Introduction: The most reliable method for bladder catheterization when necessary is to put a urethral catheter under visual control. However, this requires endoscopic equipment and transportation of patient to a cystoscopy unit or operating room, which is not always possible. To solve these problems, we have developed the optical urethral catheter Visus MG.

Contrast-enhanced ultrasound (CEUS) as a follow-up method after the focal treatment of renal tumors: systematic review and meta-analysis.

Context: Contrast-enhanced ultrasound (CEUS) is a cost-effective radiation-free diagnostic method that can be used for renal tumor postoperative visualization after ablative treatment.

Objective: To assess CEUS diagnostic accuracy comparing with CT and MRI as a follow-up method in short-term and long-term postoperative periods after renal tumor ablation.

Materials And Methods: A systematic review and meta-analysis were performed in Scopus and Medline databases using the query "(kidney OR rena* OR RCC) AND (ablation OR RFA OR MWA OR cryo*) AND CEUS".

[Efficiency and safety of Prostatex in patients with chronic prostatitis/chronic pelvic pain syndrome. Results of the phase IV PRESTIGE trial].

Introduction: A large number of both preclinical and clinical studies demonstrates the efficiency of bioregulatory peptides for the treatment of prostatitis and chronic pelvic pain syndrome (CPPS). A relatively new drug in this group is Prostatex, the active ingredient of which is bovine prostate extract.

Aim: To evaluate the effect of taking Prostatex on the intensity of CPPS, the sexual function, and the results of microscopy of expressed prostate secretions and urinalysis.

[The role of expression of monocarboxylates of the first and fourth types (MCT1, MCT4) by tumor and stromal cells of prostate cancer in determining the prognosis and the efficiency of definitive treatment].

Aim: A search for new methods for diagnosing clinically significant prostate cancer is of importance due to the insufficient accuracy of modern methods in detecting aggressive tumors. One of the promising opportunities for the early diagnosis of clinically significant prostate cancer is the assessment of the glycolytic profile of the tumor by determining the expression of monocarboxylates (MCT) types 1 and 4 in tumor cells, as well as in adjacent stromal cells.

Materials And Methods: An analysis of patients of who underwent radical prostatectomy at the Institute of Urology and Reproductive Health of Sechenov University from 2015 to 2017 was carried out.

Role of monocarboxylate transporters and glucose transporters in prostate cancer.

Objectives: Currently, research of new diagnostic approaches to detect clinically significant prostate cancer is relevant because of the importance of early detection of aggressive forms of the disease, often challenging, even when using modern diagnostic tools. The aim of this review is to present the current knowledge regarding monocarboxylate transporters' and glucose transporters' expression as a component of glycolytic phenotype definition in prostate cancer cells.

Methods: We searched PubMed and Scopus databases.

3D modeling in adherent perinephric fat prediction in nephron-sparing surgery planning in patients with localized renal neoplasms.

Study Objective: To develop a 3D-image based morphometry scoring system for Adherent Perinephric Fat (APF) prediction in nephron-sparing surgery in renal neoplasm patients.

Materials And Methods: The retrospective study involved 391 patients who underwent a laparoscopic partial nephrectomy performed by five surgeons from January 2014 till December 2018. The surgery involved the 3D virtual operation planning with «Amira» 3D modeling software.

[Adherent Perinephric Fat: a prognosis and influence of perioperative results of organ-sparing procedures in localized kidney parenchyma tumors].

The results of recently published articles on the etiology and pathogenesis of "Adherent Perinephric Fat" (APF) are presented in the review. The current possibilities for predicting the presence of APF based on clinical data and imaging methods are highlighted, as well as the to an influence of ARF on perioperative results of organ-sparing procedures using various surgical approaches in patients with localized kidney parenchyma tumors.

Three-dimensionally printed non-biological simulator for percutaneous nephrolithotomy training.

We sought to improve the educational and pre-operative training on various stages of percutaneous nephrolithotomy (PCNL) under fluoroscopic and ultrasound guidance. We developed a three-dimensional (3D) printed simulator (3D-printed PCNL model) for urological trainees. 40 s year urology residents were randomly assigned into two groups, completing PCNL surgical steps on a URO Mentor™ surgical simulator (Group A) or on our new 3D-printed PCNL model (Group B).

[Vitamin D and urinary stone disease: the current state of problem].

Disturbances of vitamin D metabolism is one of the factors leading to the impairment of phosphate and calcium homeostasis which plays leading role in the development of urinary stone disease. Vitamin D is necessary for wide spectrum of physiologic processes and good health condition. Until now, in many guidelines on urolithiasis there is an advice to limit vitamin D intake due to concerns of an increase in the stone formation.
