Comparison of Temperature Changes Between Holmium-YAG Laser and Thulium Fiber Laser in an In Vitro Setting.
Urol Res Pract
January 2025
Department of Urology, Ruby Hall Clinic, Pune, India.
Objective: We aimed to evaluate and compare the rise in the temperature for the safety of the ureter and kidney parenchyma when firing the holmium laser and the thulium fiber laser (TFL).
Methods: We performed a laboratory experiment to measure the rise in temperature upon firing holmium laser and a TFL in a 10 cm3 transparent test tube in an outdoor environment and then in a container with normal saline.
Results: In a 10 cc test tube with static water at 25°C, the rise in temperature with holmium and TFL depends on the firing time, keeping power constant.
Vacuum suction catheter semi-rigid ureteroscopic laser lithotripsy for impacted upper ureteral stones: randomised controlled trial.

Department of Urology, Zhongnan Hospital of Wuhan University, Wuhan, China.
Purpose: To evaluate the effectiveness and safety of an upgraded integrated vacuum suction catheter in semi-rigid ureteroscopic laser lithotripsy (VC-URSL) compared to traditional methods for treating impacted upper ureteral stones.
Patients And Methods: This prospective, randomized controlled trial was conducted from September 2022 to March 2024 at a single center, enrolling 95 patients aged 18 to 70 years with a single radiopaque impacted upper ureteral stone. Participants were randomized into two groups: the VC-URSL group used an integrated vacuum suction catheter featuring a stainless steel stabilizing tube and a narrowed distal end to prevent obstruction, while the T-URSL group underwent standard ureteroscopic lithotripsy without vacuum assistance.
Nonpapillary Prone Endoscopic Combined Intrarenal Surgery (ECIRS): Five-Year Experience and Outcomes from a High-Volume Center.
J Clin Med
January 2024
Department of Urology, University of Patras Hospital, 26504 Patras, Greece.
Endoscopic combined intrarenal surgery (ECIRS) provides simultaneous retrograde and percutaneous access to the upper urinary tract. The purpose of this study is to present revised data, tips and tricks, and technique modifications arising from our five-year experience with ECIRS. The data of 62 patients who underwent nonpapillary prone ECIRS from January 2019 to November 2023 were prospectively collected.

Am J Clin Exp Urol
August 2023
Department of Urology, Abiko Toho Hospital Abiko, Chiba 270-1166, Japan.
To assess the effectiveness of a pulse duration alterable Holmium-YAG (Ho:YAG) laser on the stone-free rate (SFR) compared to a conventional pulse duration fixed laser after ureterorenoscopic lithotripsy (URSL). The medical records from patients with upper urinary tract calculi of ≥ 9 mm and < 30 mm were retrospectively investigated. URSL using a conventional Ho:YAG Laser (group C) or a pulse duration alterable Ho:YAG system (group A) was included.
