Abstract
Objective: To compare regular and Moses modes of holmium laser lithotripsy during ureteroscopy in terms of fragmentation/pulverization and procedural times in addition to perioperative complications. Patients and Methods: After obtaining ethics approval, a prospective double-blinded randomized trial was conducted for patients undergoing holmium laser lithotripsy during retrograde ureteroscopy. Patients were randomly assigned to either regular or Moses modes. Patients and surgeons were blinded to the laser mode. Lumenis 120W generator with 200 Moses D/F/L fibers were used. Demographic data, stone parameters, perioperative complications, and success rates were compared. The degree of stone retropulsion was graded on a Likert scale from 0—no retropulsion to 3—maximum retropulsion. Results: A total of 72 patients were included in the study (36 per arm). Both groups were comparable in terms of age and preoperative stone size (1.4 cm vs 1.7 cm, p > 0.05). When compared with the regular mode, Moses mode was associated with significantly lower fragmentation/pulverization time (21.1 minutes vs 14.2 minutes; p = 0.03) and procedural time (50.9 minutes vs 41.1 minutes, p = 0.03). However, there were no significant differences in terms of lasing time (7.4 minutes vs 6.1 minutes, p > 0.05) and total energy applied to the stones (11.1 kJ vs 10.8 kJ, p > 0.05). Moses mode was associated with significantly less retropulsion (mean grade was 1.0 vs 0.5, p = 0.01). There were no significant differences between both modes in terms of intraoperative complications (11.1% vs 8.3%, p > 0.05), with one patient requiring endoureterotomy for stricture in the Moses group. Success rate at the end of 3 months was comparable between both groups (83.3% vs 88.4%, p > 0.05). Conclusion: Moses technology was associated with significantly lower fragmentation/pulverization and procedural times. The reduced fragmentation/pulverization time seen using Moses technology could be explained by the significantly lower retropulsion of stones during laser lithotripsy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
