[Acceleration of the chemolysis of kidney stones using ultrasound. Experimental study in vitro]

The dissolution of infectious renal concrements by means of percutaneous nephrostomy or ureteral catheter often requires lavage lasting several weeks. Using an experiment in vitro, the authors tried to reduce this interval by means of ultrasound. By combination of the physical effect of ultrasound with that of chemolytic dissolution of the infectious concrement was significantly accelerated. Thus, simultaneous intermittent ultrasound application to the body's surface during dissolution could considerably reduce the time needed for the concrement to dissolve in vivo.
