Despite the advent of extracorporeal shock wave lithotripsy, percutane
ous nephrolithotripsy still plays a prominent role in the management o
f large and staghorn renal calculi. Modalities available for intracorp
oreal lithotripsy include ultrasound, electrohydraulic, and laser. I r
eport my experience with the Swiss Lithoclast in performing percutaneo
us nephrolithotripsy in 45 patients. The advantages of this device in
percutaneous stone removal include its rapidity, safety, ease of use,
and usefulness in clearing the initial calix during staghorn stone rem
oval.
