In addition to its standard use in the ureter with semi-rigid instruments, the U100Plus is also well suited for the treatment of kidney stones within the scope of a therapy. Concrements located in the lower renal calyx, for example, are also easily reached and fragmented due to the highly flexible, super thin quartz fiber. Even large bladder stones are treated faster and with that more time- and cost-efficient using the U100Plus.

The energy of the FREDDY® lithotriptor is transferred to the stone via a highly flexible quartz glass fiber and effects fragmentation with shockwaves generated directly on the application site.
The dual laser pulse of the FREDDY® technology contains a primary infrared part (wavelength = 1064 nm) as well as a green part (wavelength = 532 nm), which is optimally absorbed by the stones. Plasma is generated at the absorption site that is amplified by the infrared part. The plasma energy then converts to a shockwave with a mechanical effect, which in turn fragments the stone in a highly efficient manner. Because the surrounding tissue practically does not absorb the emitted green part level, plasma with a subsequent shockwave is not generated here either. This means the non-thermal method of this method neither coagulates nor perforates tissue even in case of accidental direct fiber contact.
This functional principle is the basis for the demonstrably high safety standard of the lithotripsy laser U100Plus.
