ENDOUROLOGY

Relevance.The appearance of disposable flexible ureteroscope on the market is a significant breakthrough in endourology. Routine implementation of flexible ureteropyeloscopy in clinical practice impliessignificant costs for initial acquisition and subsequent expensive maintenance of endoscopes.In addition, aer plasma sterilization it is not always possible to achieve complete sterility in the working channel of the instrument, which can lead to the development of infectious and inflammatory complications with severe consequences for the patient.

Duplication of the urethra is a rare abnormality, which forms during embryogenesis from the urethral groove. Up to the date, only about 500 cases of urethral duplication have been described. Its most common form isthe formation of the paraurethral duct.This abnormality is not followed by any symptoms and may be revealed only in case of infection by the signs of dysuria, which are similar to the clinical course of acute prostatitis or urethritis. Forthe diagnostics of the condition, thoroughful history taking, symptom analysis, ureteroscopy and retrograde urethrography should be performed.

Introduction. Surgical treatment of stones in the proximal region of the ureteral duct is a complex clinical issue. Despite the availability of various methods of endoscopic treatment, the use of standard approaches does not allow to achieve the optimal results in a number of cases. The application of elastic ureterostenoscopes as a part of a combined treatment allows to overcome the intraoperative complications and technical limitations of rigid endoscopes, and also to increase the effectiveness of the intervention.

Introduction. there is lack of specific guidelines regarding the choice of ureteral stent type and duration of postoperative renal drainage after endoureterotomy. Aim of our study is to examine the influence of calyceal drainage type and duration after endoureterotomy.

The aim of the study is to compare the effectiveness and safety of two operative techniques of treating patients with benign prostatic hyperplasia (BPH) – endoscopic diode laser vaporization and endoscopic diode laser enucleation.

Aim. To assess the perioperational parameters of laparoscopic pyeloplasty performed by the method of single incision laparoscopic surgery (SILS) in comparison with standard laparoscopy.

Patients and methods. 36 patients underwent pyeloplasty using SILS, 101 patients underwent standard pyeloplasty. Parameters evaluated: duration of the operation, blood loss, use of analgesic therapy, duration of hospitalization after surgery, complications, success rate of the operation.

Introduction: the aim of our study was to obtain relevant characterization of patients with stones in the bladder and also to evaluate the results of endoscopic treatment in the conditions of a modern urological clinic.

Materials and methods: the prospective study included data of 79 patients, who underwent endoscopic removal of stones from the bladder in urological departments of the university hospital of the Moscow State University of Medicine and Dentistry in 2016.

Introduction: Currently, the treatment standard of patients with renal masses and a nonfunctional kidney are endovideo-surgical operations, among which the least invasive are laparoendoscopic single-site (LESS) operations.

Objective: Studying of the LESS nephrectomy (LESS-N) learning curve, its effect on the operations results, and comparative analysis of the LESS -N and conventional laparoscopic nephrectomy (CLN) results.

Amputation of the ureter is a complication in which its separation occurs on two levels. The frequency of this complication in the world literature varies from 0.1 to 0.2%. From 2008 to 2015 in the urological clinic MONIKI n. M.F. Vladimirsky 545 years endoscopic operations were performed in 506 patients with ureterolithiasis. In our study, ureteral amputation was noted in one observation (0.2%). One of the possible mechanisms of amputation of the ureter may be the invagination of its wall in the zone of the calculus.

Purpose. The objective was to develop an anatomically rate, nonbiologic, cost-effective model of renal collecting system and upper segment of ureter for training PCNL access under fluoroscopic guidance in cases of complex kidney stones.
