Paper Abstract

In vitro study: 53 calculi were fragmented (Technomed pulsolith, 6OmJ/pulse, 2Hz). Initial visible stone damage and disruption into at least 2 large pieces were rapidly achieved (means of 20 to 1 53 pulses respectively). The disintegration to fragments 5mm or less was obtained after a mean of 780 pulses and required for 26% of stones more than 10 mm to be achieved. Decreasing stone size, stone mass, and an increasing bilirubin with a decreasing cholesterol content correlated significantly with the more rapid achievement of satisfactory fragmentation.
