Materials And Methods: A comparative analysis of the results of percutaneous nephrolithotripsy performed under ultrasound and endovisual control in 515 (84.1%) patients (main group) and percutaneous nephrolithotripsy performed under fluoroscopic control in 97 (15.

[Unilateral combined lap partial nephrectomy and pyelolithotomy for ipsilateral tumor & kidney staghorn stone].

Objective: To discuss the feasibility, safety, and effectiveness of conventional laparoscopic partial nephrectomy combined with pyelolithotomy for patients with ipsilateral renal tumor and staghorn kidney stone.

Materials And Methods: Retrospective multicentral comparative study. Group "Combo" was presented by patients with the mentioned combined pathology (n=15).

The Technique of Thyroid Cartilage Scaffold Support Formation for Extrusion-Based Bioprinting.

During biofabrication, a tissue scaffold may require temporary support. The aim of this study was to develop an approach of human thyroid cartilage scaffold temporal support formation. The scaffold 3D-model was based on DICOM images.

[Individual-specific symptoms of malignant neoplasms of the oropharynx occurring in otolaryngologist's practice].

According to statistical data given in the article the incidence of oropharyngeal cancer increases, despite the ease of access to the maxillofacial area and the possibility to make visual and manual examination of this site. It should be stressed that locally advanced oropharyngeal cancer of the III-IV stages was the first diagnosis in 82.9% of patients.

[LAPAROSCOPIC PARTIAL NEPHRECTOMY FOR KIDNEY TUMORS R.E.N.A.L. SCORE 10 and HIGHER].

Objective: To discuss the feasibility, safety, and effectiveness of conventional laparoscopic partial nephrectomy for patients with kidney tumors R.E.N.

[Laparoscopic ureteral substitution: ileocalicostomy combined with psoas hitch].

A 50-year-old female presented to our department of urology with nephrostomy drain in the right kidney been placed because of an acute obstructive pyelonephritis. Nephrostogram revealed an intra-renal pelvis with no passage of contrast into the ureter. Retrograde pyelography identified the extended ureteric stricture and need for a substitution.

[Economic aspects of treatment for lower urinary tract symptoms associated with benign prostatic hyperplasia].

A review of the literature dedicated to the economic aspects of drug and surgical treatment of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) is presented in the article. Currently, symptomatic therapy, which usually leads to an increase in the financial costs associated with the complications and surgical treatment, is most commonly used. The pathogenetic treatment of BPH (5-alpha reductase inhibitors), including combination therapy, requires an increase in costs, but it is also considered the most cost-effective approach.

[Specific features of the immune status and blebbing of the plasmatic membrane of lymphocytes patients with urolithiasis complicated by the pyelonephritis].

Introduction: According to the epidemiological studies, prevalence of urolithiasis is nearly 10% worldwide. The course of the disease is often complicated by the development of pyelonephritis, the pathogenesis of which is rather multifactorial. Along with urinary tract obstruction, increasing virulence of microorganisms and immune insufficiency in patients also plays a major role.

[A case of successful plasma transurethral enucleationof benign prostatic hyperplasia the size of 530 cm3].

The article presents a description of the clinical case. Surgical treatment by plasma transurethral enucleation of the prostate was performed in patients with benign prostatic hyperplasia of giant size - 530 cm3. Observation in the short term showed the absence of functional and organic complications.

[Horseshoe kidney tumor laparoscopic surgery. First 19 cases].

Introduction: Although horseshoe kidney (HSK) is the most common congenital anomaly of the upper urinary tract, renal cell cancer (RCC) in HSK develops extremely rarely. Until 2012 y. there were less than 200 cases of RCC in HSK published in PubMed.

[Laparoscopic ileal ureteral substitution. Results of the first 40 operations].

Introduction: Despite the twenty-year history of laparoscopic ileal ureteral substitution, the literature is lacking studies reporting its outcomes, and those few are mainly case reports. Besides, they usually describe surgery from combined access, when the ileal segment resection and ileo-ileal anastomosis are performed from mini-laparotomy, and the remaining stages are done endoscopically.

Aim: To conduct a multicenter retrospective analysis of our series of patients undergoing laparoscopic ileal ureteral substitution using only endoscopic access.

[Laparoscopic segmental ureteral resection with ileal-ureter substitution for ureteral urothelial carcinoma].

Ureteral resection for the mid-ureter urothelial carcinoma is the operation of choice in patients with low-grade tumors. However, extensive excision within normal tissues may lead to difficulty in appropriate apposition of the ends of the ureter, while incomplete resection increases the risk of oncological progression. This article describes the first experience with laparoscopic segmental ureteral resection with the ileal - ureter substitution for mid-ureter urothelial carcinoma.

[Peculiarities of the early diagnostics of malignant nasopharyngal neoplasms].

The authors consider the risk factors and the specific clinical symptoms of the malignant nasopharyngal neoplasms as well as the methods for instrumental, laboratory, and pathomorphological diagnostics of this pathology. The full scale implementation of the recommendations for the timely detection of the tumours using the aforementioned diagnostic procedures and tests makes it possible to reduce to a minimum the interval between the establishment of the diagnosis and the onset of the relevant treatment at the early stages of the disease and thereby to ensure the improvement of its long-term outcomes.

[Laparoscopic pyelolithotomy for staghorn kidney stones. multi-center study].

Aim: To analyze the effectiveness and safety of laparoscopic pyelolithotomy (LP) in treating staghorn stones.

Materials And Methods: A multicentre retrospective analysis of the results of LP performed from January 2004 to December 2016 was conducted.

Inclusion Criteria: patients with staghorn calculi K3-K4, who underwent LP as an alternative to percutaneous nephrolithotripsy.

[Initial experience with laparoscopic anatrophic nephrolithotomy].

Percutaneous nephrolithotomy is a recognized standard for minimally invasive treatment of large kidney stones. Percutaneous interventions for complete staghorn stones are associated with a higher risk of complications that precludes abandoning the traditional open operations, one of which is an anatrophic nephrolithotomy. This paper presents the first personal experience in laparoscopic transmesenteric anatrophic nephrolithotomy.

Unlabelled: The incidence of thyroid cancer (TC) is being significantly increased. A significant percentage consists of metastatic cancer (MCP) in particular in the anterior-superior mediastinal lymph nodes (Group 7).

Material And Methods: 153 out of 324 patients with metastatic TC underwent video-assisted lymphadenectomy of group 7 of lymph nodes.
