Selection between individual and combined
modes
The Swiss LithoClast
®
Select System offers two modes of lithotripsy;
ultrasound lithotripsy and pneumatic direct impact lithotripsy, known
as the Swiss LithoClast
®
principle.
These two lithotripsy modes can operate in combination or individually.
The selection of the treatment mode depends on the stone location
and on the stone properties.
Stone fragmentation testing has been conducted to verify that
simultaneous use of ultrasound and shock wave pneumatic lithotripsy
can reduce the time needed for stone fragmentation and evacuation.
In situations where it is time consuming and hard to fragment the
stones by using ultrasound energy alone, the simultaneous application
of the pneumatic probe guided through the ultrasound probe can
considerably improve the process. This is particularly true when
treating hard stones, such as mono hydrate stones.
The combined use is not indicated when the fragmentation process
works fine with the ultrasound probe alone. The flow characteristic of
the ultrasound probe is limited when the pneumatic probe is inside.
Fragment evacuation is more efficient when the suction channel is
kept free.
