Video 1Details regarding the patient's clinical presentation and prior endoscopic treatments for common hepatic duct stricture are first described in the video. Next, the video features footage from subsequent ERCP demonstrating the common hepatic duct stricture both fluoroscopically and endoscopically via cholangioscopy, followed by treatment with thulium laser stricturoplasty/dissection. The immediate post-treatment images of the stricture are displayed which demonstrated marked improvement in the stricture. Finally, the patient's ensuing clinical course is displayed in which the stricture recurred and was retreated with laser stricturoplasty/dissection and stent upsizing.

To assess the accuracy of Kidney Stone Calculator(KSC), a software designed for surgical planning, in predicting the duration of lithotripsy during flexible ureteroscopy(FURS) when using the novel pulsed-Thulium: YAG(p-Tm: YAG) laser. From February to August 2023, a single-center prospective study was conducted, including patients with kidney or ureteral stones through non-contrast computed tomography(NCCT), who underwent FURS with p-Tm: YAG laser lithotripsy. KSC used three-dimensional segmentation of the stones from NCCT images, along with an interactive user interface for laser settings, to estimate the stone volume(SV) and the lithotripsy duration(LD).

Contemporarily, pulsed mode thulium laser has been reported to confer adequate hemostasis. Therefore, the primary outcome of this study was to assess safety and efficacy of thulium laser-based hemostasis during PNL.

Purpose: Use of suction in flexible ureteroscopy is increasing lately. The introduction of flexible and navigable suction access sheath (FANS) has shown improved stone free rate (SFR). However, its efficacy in lower pole stone (LPS) in terms of SFR and complications is yet to be studied.

Objective: To evaluate the impact of three different AEEP techniques on the training performance of novices using a realistic hydrogel prostate phantom model.
Material And Methods: The experimental setup utilized realistic prostate phantom model provided by the Max Planck Institute for Intelligent Systems, Germany. For the enucleation, we utilized a new solid-state pulsed thulium laser (Thulio®, Dornier MedTech, Weßling, Germany).

Simulation studies on temperature distribution in laser ablation help predict ablation rates, laser settings, and thermal damage. Despite the limited number of reported numerical studies on the temperature distribution of kidney fluid, there is no simulation study for kidney stone temperature distribution. We employ a numerical approach to study the kidney stone temperature distribution and predict ablation rates, which is an important parameter for clinical lithotripsy.
