Dusting v. Basketing: Strategies for Disintegrating Renal St
Ureteroscopic (URS) laser lithotripsy is one of the most common procedures for treating ureteral stones and kidney stones less than 2.0 cm in diameter. Traditionally, a high-power, low-frequency holmium laser has been utilized to fragment the stone into pieces, which are then extracted using a basketing procedure.

However, researchers from the Massachusetts General Hospital Department of Urology recently participated in a multi-institutional clinical study testing an alternative to basketing. The new protocol, called dusting, uses newer laser technologies—a holmium laser set to lower power but significantly higher frequency—which often results in ablation of stones into dust-like particles that pass naturally. According to the study, performed by the Endourology Disease Group for Excellence (EDGE) Research Consortium, this approach provides equally successful outcomes but at a potentially lower cost and shorter surgical time.
