[Endothelial dysfunction in urolithiasis patients].

To characterize endothelial dysfunction in operated nephrolithiasis patients, we studied NO, VEGF, ET-1, IL-6 concentration in the blood serum and NO in the urine of nephrolithiasis patients divided into three groups by the type of surgical treatment before operation, 7-10 days and 1 month after it. We used beta-2 microglobulin as an indicator of tubular dysfunction. We found a significant rise of a concentration of the endothelial dysfunction markers ET-1, IL-6 and VEGF in the blood serum (p < 0.05), showing endothelial dysfunction in nephrolithiasis patients, especially in early postoperative period after multiple exposure to short-wave lithotripsy. One month after open surgery or lithotripsy a complete recovery of endothelial function was not recorded.
