Good news!
"... Currently being developed by scientists ... it utilizes a portable machine to generate swirling ultrasound waves known as acoustic vortex beams.
Instead of hitting the stones straight-on, as is the case with ESWL [extracorporeal shock wave lithotripsy] pulses, these beams spin around the stones like twister tornados. As they do so, they produce shear forces on the stones that cause them to disintegrate. ..."
"Lithovortex is a low-cost, portable device capable of destroying stones non-invasively, thanks to the application of ultrasound - it transmits waves from the outside to focus them inside the body, on the stone. According to the tests, its application halves the time needed to break up a stone. In addition, the size and portability of this device would make the treatment of kidney stones an outpatient procedure without the need for large accessory equipment, as is currently the case. ..."
