DYNAMICS OF THE CONCENTRATION OF PROFIBROGENIC BIOMARKERS IN BLOOD AND URINE IN PATIENTS WITH ACUTE UPPER URINARY TRACT OBSTRUCTION

Renal calculi most often lead to impaired urine flow.They occur in 40-43% of urological patients.Patients with urolithiasis always have an increased risk of developing acute or chronic kidney disease with impaired renal function and changes in its morphological structure, regardless of the size of the stone and the duration of its stay in the upper urinary tract.The analysis of the literature of the last five years has shown the crucial role of transforming growth factor- (TGF-), monocyte chemoattractant protein-1 (MCP-1) and insulin-like growth factor-1 (IGF-1) in the development of renal fibrosis during acute upper urinary tract obstruction (AUUTO).Their complex interactions and dynamics in serum and urine reflect the progression of renal damage and fibrosis and can be used as biomarkers of renal fibrosis.The study aimed to determine the dynamics of profibrogenic biomarkers in blood and urine in acute ureteral obstruction.We studied 50 patients with unilateral acute upper urinary tract obstruction.The concentration of TGF-, MCP-1, IGF-1 in blood and urine was determined by enzyme-linked immunosorbent assay.In acute upper urinary tract obstruction in patients during the first 7 days, the levels of profibrogenic biomarkers (TGF-, MCP-1, IGF-1) in the urine significantly increased, indicating the possible onset of sclerotic changes in the kidneys.TGF-, MCP-1 and, to a lesser extent, IGF-1 in blood and urine are markers of renal fibrosis development in acute upper urinary tract obstruction.Their dynamic changes in serum and urine reflect the progression of renal damage and can provide valuable information about disease mechanisms and potential therapeutic approaches.
