[Colon injury during percutaneous nephrolithotomy (clinical case, literature review)].

Urolithiasis occupies one of the leading places in terms of the frequency of requests for urgent urological care and emergency hospitalization in specialized departments. Percutaneous surgery for urolithiasis, like any of the surgical methods, is associated with a number of specific and non-specific complications. Of course, the frequency of occurrence is dominated by hemorrhagic and inflammatory complications.

[Hemorrhagic complications of percutaneous interventions for nephrolithiasis].

Unlabelled: Hemorrhagic complications are one of the major problems of percutaneous urolithiasis interventions.

Aim: To investigate the incidence of hemorrhagic complications after percutaneous nephrolithotripsy.

Material And Methods: This was a comparative analysis of 146 percutaneous nephrolithotripsies.

[Extracorporeal partial nephrectomy, is it worth?].

Objective: To assess the effectiveness of extracorporeal partial nephrectomy.

Material And Methods: The article presents a comparative analysis of 65 radical nephrectomy, 47 partial nephrectomy and 5 extracorporeal partial nephrectomy on the renal parenchymal tumors.

Results And Discussion: This article discusses the advantages and disadvantages of extracorporeal partial nephrectomy in comparison with the intracorporeal interventions.

[COMPLICATIONS OF STENTINGOF UPPER URINARY TRACT].

Restoring the passage of urine through the upper urinary tract routinely is achieved by installing of external or internal drainage. Due to its objective advantages, internal drainage has been successfully used in surgery of the upper urinary tract. This review outlines the problems associated with the use ofinternal stents, namely difficultyin installation, migration, and reflux and stent obstruction, bacterial colonization of the stent, the development of functional and morphological changes in the drained segment of urinary tract.

[EFFECTIVENESS OF URETERAL STENTS WITH NANOSTRUCTURED COATING IN RENAL TRANSPLANTATION (PRELIMINARY RESULTS)].

From a surgeon's perspective, intraureteral jj-stent is an optimal tool to ensure upper urinary tract drainage. This paper presents preliminary results of our study investigating the use of ureteral stents with nanostructured coating in renal transplant recipients. The use of nanostructured coating based on amorphous carbon and silver nanocrystallites eliminated bacteriuria by week 4 after stenting in the treatment group with significant decrease of urine sediments while in the control group bacteriuria was found in 83,3% cases.
