1 June 1992 In-vitro tests of excimer laser lithotripsy in urinary stones

A long pulse XeCl excimer laser (200 ns) was used to induce fragmentation of human urinary stones and artificial models during 'in vitro' experiments. High UV energy fluences, up to 50 J/cm2, could be delivered to the samples by means of silica optical fibers. Fragmentation thresholds of the different samples were observed in the range 5 - 20 J/cm2, well within the energy capability of the fibers. Total fragmentation was always successfully achieved, requiring a variable number of pulses (10 - 100), depending on the pulse energy and the hardness of the sample. The effects of ultraviolet laser radiation on urinary stones are also compared with those of commercial Alexandrite and dye lasers.
