With great power comes great risk: High ureteral stricture rate after high-power, high-frequency Thulium fiber laser lithotripsy in ureteroscopy.

ABSTRACT:

Purpose

To compare the safety and efficacy of Thulium Fiber Laser (TFL) using either manufacturer presets (MP) or individualized presets (IP) in ureteroscopy.

Methods

Multi-institutional, retrospective analysis on the first patients treated with SOLTIVE^® Premium (Olympus Medical Systems^®) TFL in Switzerland in 2020. MP were used at the University Hospital of Geneva, while IP were used at the University Hospital of Zurich. Patient demographics, stone characteristics, and procedural details were collected. Primary outcome was postoperative ureteral stricture (US). Secondary outcome was stone-free rate (SFR).

Results

A total of 158 patients were analyzed, 79 in each group. Demographics were similar between the two groups, except for a lower pre-sten
