Dynamics of angiogenesis and inflammation biomarkers in patients with urolithic disease with obstructive uropathy

<p>Purpose: to establish the nature of changes in markers of angiogenesis and inflammation in the blood serum and urine in patients with obstruction of the ureteropelvic segment or upper third of the ureter by ureteral stones in different terms of the kidney drainage. Material and Methods. 53 patients with urolithiasis have been examined. The main group consisted of 33 patients with concrements of the upper third of the ureter or renal pelvis-ureteral segment with pres- ent obstructive uropathy. The comparison group consisted of 20 patients with calculi of the kidney without symptoms of obstruction. In the main group patients underwent drainage of the kidney by percutaneous-nephrostomy puncture. Results. Patients of the main group revealed a significant increase in the levels of markers of angiogenesis and inflammation before the kidney drainage. The level of MCP-1 correlated with the level of serum creatinine. In the process of drainage the levels of these markers were decreased as a result of increased GFR. Determination of the concentration of urinary VEGF, IL-8 and MCP-1 in patients may have clinical value in personalized management of patients with obstructive uropathy to determine the optimal terms of the second stage of the surgical intervention. Conclusion. Determination of markers of inflammation and angiogenesis in the urine of patients in conjunction with assessment of renal function by creatinine level is important for determining the term of kidney drainage.
