What is Temperature Measurements During Flexible Ureteroscopic Laser Lithotripsy: A Prospective Clinical Trial about?

Objective: The primary aim of the study was to explore intrarenal temperatures (IRTs) during flexible ureteroscopic laser lithotripsy (FURSL). Secondary aim was to investigate correlation between temperatures and renal pelvis anteroposterior diameter (APD). ## Material and Methods: From February 2023 to June 2023, 10 patients with an indwelling nephrostomy tube (NT) undergoing FURSL were enrolled in the study. Sheathless FURSL was performed using gravitational irrigation (23°C) at 60cm. A sterile K-type thermocouple was inserted through the NT. Temperatures were recorded for 120 seconds (s) with continuous laser activation and for another 60s after deactivation. Thulium Fiber Laser delivered energy using a 150μm fiber and incremental power settings of 5W, 10W, 20W and 30W. The laser was deactivated whenever IRT reached 43°C. Results: IRT correlated directly to power settings. Each time the power settings were increased, the temperature rose significantly. The increase in average peak temperature was 2.6°C between 5-10W (p < 0.001), 3.4°C between 10-20W (p < 0.001), and 2.5°C between 20-30W (p 20mm with the same power settings applied, p < 0.001. ## Conclusion: During FURSL, IRT c
