Ureteroscopic High-Frequency Dusting Utilizing a 120-W Holmium Laser

Abstract: Refinements in laser technology have expanded methods to ablate urinary stones. Outcomes utilizing a dusting technique demonstrated acceptable RF and complication rates. However, not all stones are amenable to dusting, and further study is needed to define the optimal role of this technique during laser lithotripsy.

“…Moreover, passage of stone fragments is associated with more emergency department visits and renal colic [16]. Several recent modifications in laser machines have included very high frequency (50-80 Hz) [17] or long pulse duration [18] to improve the SFR of the dusting technique. However, these modifications are only available in high-power laser machines (120 W), which are more expensive than 20-or 30-W laser machines.…”

“…During laser lithotripsy, dusting technique usually needs the laser setting of low-pulse energy and high frequency [ 18 ]. A recent investigation assessed surgical outcomes of dusting technique in 82 renal units of 71 patients utilizing 120 W Ho:YAG laser with 200-μm fibers [ 19 ]. The mean stone size was 12.5 ± 8.7 mm and the mean Hounsfield unit was 993 ± 353.…”

“…While the number of laser lithotripsy modes used for ablation of urinary stones has proliferated in recent years, in general, there are at least three major techniques that are used, including “dusting” [ 28 33 ] (low pulse energy, high pulse rate) to particles typically defined as less than 1 mm in size, “fragmentation” [ 31 , 32 ] (high pulse energy and low pulse rate) with subsequent basketing of larger stone fragments (> 2 mm), and “popcorning” [ 34 38 ] where the fiber is held fixed in place and high pulse energy is used to create turbulent flow and break down multiple small stones trapped within a calyx in the kidney, when basketing of multiple stones is not judged to be feasible or efficient. Combinations of these operation modes (e.g.…”
