[Use of phenomenon of adsorption decrease in solid cohesion for remote lithotripsy (experimental study)]

The possibility of using the phenomenon of adsorption decrease in solid cohesion well known in the colloid chemistry as Rebinder effect for nephrolith remote destruction was studied. Sorption properties of urine components in healthy persons and those suffering from urolithiasis were compared. The number of synthetic surfactants were studied according to the values of bordering moistening angle and efficiency of remote destruction of firm nephrolithes in vitro. The bordering moistening angle measurements have shown that the urine of healthy persons demonstrates higher surface activity compared with the urine of those suffering from urolithiasis. The correlation between the value of bordering moistening angle for the liquid into which the urolithiasis was immersed and the destruction efficiency in vitro in that media was established. The efficiency of nephrolith destruction was found to increase in the water solution of chlorhexidine bigluconate.
