OBJECTIVES: We tested the hypothesis that retropulsion varies with stone size. METHODS: Stone phantoms of uniform cube dimensions were constructed and irradiated with Ho:YAG energy (0.5 J - 3.5 J). Displacement was measured. RESULTS: At any given pulse energy, retropulsion decreased as stone size increased, p<0.05. At any given stone size, retropulsion increased as pulse energy increased, p<0.05. CONCLUSIONS: A strategy of low pulse energy at high repetition rate is appropriate for ureteral stones. For larger bladder and renal stones, retropulsion is minimal even with high pulse energies. More study is warranted.
