We report clinical results with the Lithocut C-3000 shock wave lithotriptor used in treatment of kidney and ureteral stones. The Lithocut C-3000 is a low-cost device. There is no need for anaesthesia. The overall success rate after 3 months was 64% in 143 treatment sessions of 120 stones. For small stones (diameter < 10 mm), the success rate was 69% and for stones with a diameter > or = 10 mm, success was achieved in 60%. The treatment-associated morbidity was low. The Lithocut C-3000 device appears to be safe and effective, suitable for small centers.
