Flexible ureteroscopy combined with Holmium-YAG laser is an effective, reproducible and minimally traumatic diagnostic and therapeutic technique perfectly adapted to diseases of the upper urinary tract. This technology must be part of the therapeutic armamentarium of any centre involved in the management of urinary stones. The technical facilities must be complete and adapted. Flexible ureteroscopy is a technique with a rapid learning curve once the operator is familiar with all of the equipment. This article describes the material and technique of flexible ureteroscopy combined with Holmium-YAG laser.

High mobility emissive organic semiconductors (HMEOSCs) are a kind of unique semiconducting material that simultaneously integrates high charge carrier mobility and strong emission features, which are not only crucial for overcoming the performance bottlenecks of current organic optoelectronic devices but also important for constructing high-density integrated devices/circuits for potential smart display technologies and electrically pumped organic lasers. However, the development of HMEOSCs is facing great challenges due to the mutually exclusive requirements of molecular structures and packing modes between high charge carrier mobility and strong solid-state emission. Encouragingly, considerable advances on HMEOSCs have been made with continuous efforts, and the successful integration of these two properties within individual organic semiconductors currently presents a promising research direction in organic electronics.

Department of Stomatology, the First Medical Centre, Chinese PLA General Hospital, Beijing, 100853, China.
Objective: This study evaluated dentin morphology and pulp cavity temperature changes during nanosecond‑ and microsecond‑pulse Er, Cr: YSGG laser debonding restoration and residual adhesive.
Materials And Methods: Ten caries-free teeth had their enamel removed perpendicular to the long axis, followed by bonding of glass ceramic restorations. The samples were randomly divided into two groups and subjected to Er, Cr: YSGG laser (3 mJ, 100 Hz, 100 ns), (3 mJ, 100 Hz, 150 µs) for debonding of restoration and residual adhesive on dentin surfaces.
Rise in intraluminal temperature during ureteroscopy: Is this a concern?
Investig Clin Urol

Department of Urology, Seoul National University Bundang Hospital, Seongnam, Korea.
The global increase in urolithiasis prevalence has led to a shift towards minimally invasive procedures, such as retrograde intrarenal surgery, supported by advancements in laser technologies for lithotripsy. Pulsed lasers, particularly the holmium YAG and the newer thulium fiber laser, have significantly transformed the management of upper urinary tract stones. However, the use of high-power lasers in these procedures introduces risks of heat-related injury.

Department of Urology, Zhangjiagang Hospital Affiliated to Soochow University, Suzhou, Jiangsu, China.
Purpose: The purpose of this study was to investigate the efficacy of Transurethral Holmium Laser of the Prostate (HoLEP) with Double-n Technology in the treatment of benign prostatic hyperplasia (BPH), with a focus on preserving sexual function postoperatively.
Methods: Conducted as a multicenter, prospective, single-blind randomized controlled trial, this study enrolled sexually active male patients with BPH. Participants were randomized into three groups: standard HoLEP (Group A), single-n technology (Group B), and innovative double-n technology (Group C), which emphasizes the preservation of the urethral mucosa and nearby structures.
Laser-Driven Dissection Achieves Earlier Continence Recovery Than Blunt Dissection During Holmium Laser Enucleation of the Prostate.
Low Urin Tract Symptoms
January 2025
Farwaniya Hospital, Farwaniya, Kuwait.
Objectives: During holmium laser enucleation of the prostate (HOLEP), blunt dissection (BD) by pushing the tip of the scope may exert mechanical force on the sphincter that could be avoided by adopting laser dissection (LD). This study evaluates the continence recovery in consecutive patients who underwent BD and LD.
Methods: A prospective cohort of patients who underwent LD was compared with a retrospective control that underwent BD.
