Summary

Patients diagnosed with urolithiasis will be prospectively enrolled in this study. Preoperative diagnostic assessment will be performed using computed tomography (CT). Key parameters, including stone dimensions, quantity, total stone burden, and stone density (Hounsfield units), will be evaluated preoperatively. This study aims to analyze data from patients who undergo ureteroscopic Thulium Fiber Laser (TFL) lithotripsy and achieve a stone-free status within a single procedural session. Based on these data, a 'Specific Energy Coefficient' will be derived to enable the preoperative prediction of the total laser energy required for successful lithotripsy.

Conditions

  • Urolithiasis

Interventions

PROCEDURE

thulium fiber laser lithotripsy

Procedures were performed by two high-volume experienced endourologists. Semirigid URS (7.5-9.5 F) was utilized for ureteral stones, while flexible URS (7.5 F) with a ureteral access sheath (10/12 F or 12/14 F) was preferred for renal stones. A 200 µm Thulium fiber was employed in all cases. Fragmentation was performed in Dusting Mode (Pulse Energy: 0.1-0.2 J, Frequency: 80-150 Hz).
