Objective: To evaluate the effectiveness and safety of ureteroscopic holmium: YAG laser lithotripsy for managing ureteral calculi.
Methods: Ureteroscopic holmium: YAG laser lithotripsy was used in 168 ureteral calculi (proximal 27 cases, middle 33 cases, distal 108 cases). Transurethral cystoscopic holmium: YAG laser lithotripsy in 12 bladder calculi.
Results: Four to six weeks after operation, The stone-free rate was 93% (25/27) in the proximal ureteral calculi, 94% (31/33) in the middle ureteral calculi, 94% (102/108) in the distal ureteral calculi, respectively. The complication rate was 5% (8 cases). the stone-free rate of bladder calculi was 100% (12/12), no complication.
Conclusion: Ureteroscopic holmium: YAG laser lithotripsy is a highly effective and safe treatment modality for managing ureteral calculi.

Vacuum suction catheter semi-rigid ureteroscopic laser lithotripsy for impacted upper ureteral stones: randomised controlled trial.
Int J Surg

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.

Objectives: To investigate the effectiveness of different holmium:yttrium-aluminum-garnet (Ho:YAG) laser modes for lithotripsy in the "dusting era" and identify the optimal laser mode for producing stone fragments measuring ≤0.5 mm.
Methods: We used plaster of Paris-made artificial stones crushed into 2-3 mm pieces, weighing 1 g in total.

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).

This study aims to evaluate the feasibility, safety, and effectiveness of an optimized treatment approach for complex renal calculi, utilizing visual needle nephroscopy in conjunction with standard PCNL and holmium YAG laser. We collected data from 62 patients diagnosed with complex kidney stones who underwent this combined procedure using the visual needle nephroscope (Needle-perc, Youcare Tech, Wuhan, China). The percutaneous nephroscopic working channel was established by visual needle nephroscope, and the primary channel was expanded to 20 F to treat most of the main body of the calculi with a 550 μm holmium laser fiber.

Introduction: Despite kidney stone disease (KSD) guidelines, high-quality evidence for KSD management in Canada is lacking. We aimed to assess Canadian urologists' practice patterns, preferences, and barriers in managing KSD.
Methods: A cross-sectional survey was distributed to Canadian urologists via the Canadian Urological Association (CUA), Quebec Urological Association (QUA), and Canadian Endourology Group (CEG), as well as directly to urology departments nationwide.
