Randomized double-blind trial demonstrates reduced surgeon workload without differences in operative time for renal stones, suggesting ergonomic benefits of Moses 2.0 technology.
Key Points
To evaluate whether Moses 2.0 pulse technology during holmium laser lithotripsy reduces operative time, surgeon workload, and stone retropulsion for 8–20 mm renal stones.
Conducted a multicenter, randomized, double-blind clinical trial enrolling 153 patients (79 Standard laser, 74 Moses 2.0) stratified by stone size.
Evaluated primary outcomes of total operative time and surgeon workload via the NASA-Task Load Index (NASA-TLX), alongside secondary outcomes of retropulsion via blinded video review and clinical success, using linear regression modeling.
Total operative time showed no statistically significant difference between the standard and Moses 2.0 groups (P = 0.73), and stone retropulsion rates were also similar (P = 0.13).
Moses 2.0 was associated with significantly reduced effort, frustration, mental, physical, and temporal workload, as well as higher rated overall surgeon performance.
Complication rates (13% in Standard vs 10% in Moses 2.0) and stone-free rates (51% in Standard vs 55% in Moses 2.0) did not differ significantly between treatment arms.
