Research objective: The study investigates the antifibrotic nephroprotective effects of aliskiren on the condition of renal hemodynamics, changes of profibrotic cytokines level and markers of renal damage in patients with nephrolithiasis undergone various types of surgery. Materials and methods: Patients have been divided into 2 groups. The investigations have been performed before the surgery and in a month period. Concentrations of TGF-p, markers of acute renal tubulointerstitial damage — NGAL and p2-microglobulin in urine, levels of ET-1 in serum and indicator of endothelial dysfunction have been determined. Assessment of renal blood flow state by Doppler ultrasonography has been carried out in the same terms. Results: As a result of aliskiren treatment the decrease of mediators of tubulointerstitial damage and nephrofibrosis, significant improvement in renal blood flow in a month period after the surgery have been marked in comparison with the group which had not received nephroprotective therapy. Conclusion: Direct renin inhibitor aliskiren may be used as a means of renal protection therapy in treatment of patients with nephrolithiasis.

The aim of this study was the estimation of clinical importance markers of renal damage at surgical treatment of nephrolithiasis. We studied results of operations in 110 patients with nephrolithiasis. The study presents new candidates for biochemical markers of acute kidney injury and renal interstitial fibrosis, with potentially high sensitivity and specificity. In this study were measured the concentrations of these biomarkers in urine. We suggested, that increased concentrations molecular mediators of renal damage (L2, IL-18) and interstitial fibrosis (MCP-1, TGFp, IGF1) in the patients with nephrophibrosis and strongetubulointerstitial injury, saved long-time period after operation, has been shown of progression chronic kidney disease

The aim of the study is to evaluate the influence of angiotensin converting enzyme (ACE) inhibitors of quinapril on the condition of renal hemodynamics, changes of profibrotic cytokines level and transforming growth factor at patients with nephrolithiasis undergone various kinds of surgery. Patients were divided into 2 groups initially and in 1 month after surgery. Concentrations of IL-6, TGFp and МСР-1 were determined in blood serum. Assessment of renal blood flow state by Doppler ultrasonography was performed in the same terms. As a result of quinapril treatment the decrease of МСР-1, TGFp and IL-6 was marked in comparison with the group which did not receive nephroprotective therapy. The analysis of Doppler ultrasonography data showed authentic improvement of renal blood flow in 1 month after surgery. The most informative parameter proved to be the resistance index that indicated the decrease of vascular resistance after surgical treatment in condition of quinapril therapy
