Selection of lithotripsy mode
The following table shows which Ultrasound Probe size and Pneumatic combination Probe size is used for various stone types and locations:
Lithotripsy Mode
Stone Type
Ultrasound only
Pneumatic & Ultrasound combination
Hard kidney stones through percutaneous
access (monohydrate, cystine stones)
Ultrasound probe: 3.3 mm or 3.8 mm
Use ultrasound lithotripsy only for hard stones
after initial fragmentation with the pneumatic /
ultrasound combination (see directions for intra-
operative change between combination hand-
piece setup and ultrasound only)
Ultrasound probe: 3.3 mm or 3.8 mm
Pneumatic probe: 1.0 mm
Pneumatic probe 1.3 mm (optional) for use
with 3.8 mm Ultrasound Probe only
Soft kidney stones (struvite, matrix stones)
Ultrasound probe:
3.3 mm or 3.8 mm
Ureteral stones
Ultrasound probe:
1.5 mm
Hard bladder stones
(monohydrate stones)
Ultrasound probe:
3.3 mm or 3.8 mm
This method can be used for fragment removal
following the pneumatic fragmentation
Ultrasound probe: 3.3 mm or 3.8 mm
Pneumatic probe: 1.0 mm
Pneumatic probe 1.3 mm (optional) for use
with 3.8 mm Ultrasound Probe only
Soft bladder stones
Ultrasound probe:
3.3 mm or 3.8 mm
Small kidney stones
Ultrasound probe 1.9 mm for use with mini
nephroscopes with 6 Fr. work channel size
