So there is a debate amongst surgeons whether to laser the stone to dust or fragment and retrieve intra-renal fragments. EAU guidelines on the surgical management of urolithiasis stated that dusting strategies should be limited to the treatment of large renal stones. Without clearly differentiating between dusting or fragmentation and basketing. Cho et al; favored fragmentation technique especially for large renal stones (> 10 mm) because the dust in dusting technique may affect visualization and obscure small stone fragments. But this was an opinion and not built on a direct comparative study.
