Seattle: American experts have performed successful experiments on breaking kidney stones with ultrasound waves.
The technology, called "burst wave lithotripsy" (BWL), was invented a few years ago by a team of scientists at the University of Washington, Seattle, and has been tested on 19 volunteers in new experiments.

All volunteers had kidney stones measuring 12 millimeters or more.
During these experiments, ultrasound waves were focused on each kidney stone for about ten minutes.
In this short time, 90% of the volume of the rocks was broken down into rocks 2 mm or smaller, while 39% of the rocks were completely dissolved.
Most patients did not have any discomfort during this ultrasound operation. However, after the operation, there was some blood in his urine for some time. No other side effects were observed in the volunteers.
The discomfort of the patients during the operation was so great that they did not even need to anesthetize or listen to the affected area.
This technology, which eliminates kidney stones with the help of concentrated ultrasound waves, will be further improved in the near future to become the basis for a new, low-cost and unique treatment, which will not cause the patient any discomfort.
Note: Details of this research have been published in the latest issue of The Journal of Urology.
