The idea of dusting in RIRS emerges as a counterpart of the originally taught fragmentation and basketing of the stones. Aiming to reduce multiple entries and exits for the renal system and ultimately not requiring UAS or baskets during the surgery. Thus theoretically decreasing operative time and costs with the same SFRs, In addition to minimizing the risk of ureteral injury .A recent survey done by the Endourology Society revealed that two thirds of the respondents were using dusting technique (using a high-frequency, low-pulse energy setting, such as 30-50 Hz × 0.2-0.5 J, which seeks to fragment stones to a finepowder and small fragments).However, the survey did not provide clinical data on if dusting is better than fragmenting and basketing.
