Abstract:
The urine concentration of IL-6, IL-8 and nitric oxide (NO) were determined in the patients with pyelonephritis and hydronephrosis. Correlations between urine levels of IL-6 and IL-8 and amount of nitric oxide in the hydronephrosis patients were not found. However, in the patients with both acute and chronic pyelonephritis the coefficient of correlation was high, r((IL-6/NO)) = 0,94 and r((IL-8/NO)) = 0,86 for acute and r((IL-6/NO)) = 0,72 and r((IL-8/NO)) = 0,40 for chronic forms, respectively. These data suggest that secretion of NO during hydronephrosis has a compensatory character and acted on renal microvascular tone, whereas during pyelonephritis NO produced inflammatory mediators by recruiting leukocytes and has pathogenic character.
