Comparison of laser performance for diode-pumped Tm:YLF of various doping concentrations

, 2005
Single-end-pumped laser performance of 2, 4, and 6at.% Tm-doped YLF rods is reported. For the pumping configuration employed, crystal fracture was observed to occur for a thermal load per unit absorption length of ~13W/cm.

Clinical Evaluation of the Effectiveness of Digital Peroral Cholangioscopy‐Guided Lithotripsy for Difficult Bile Duct Stones

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background and Aims Peroral cholangioscopy‐guided lithotripsy (POCS‐L) has emerged as a treatment option for difficult bile duct stones (DBDSs), but detailed evidence remains limited. This study evaluated its effectiveness, safety, and risk factors for adverse events (AEs).

Lipid and Foam Cell Accumulation as Novel Pathological Features of Benign Prostatic Hyperplasia

The Prostate, EarlyView.
ABSTRACT Background Benign prostatic hyperplasia (BPH) encompasses a heterogeneous set of pathological processes that instigate lower urinary tract symptoms (LUTS). Using a mouse model of steroid hormone imbalance–induced lower urinary tract dysfunction, we identified luminal lipid‐laden foamy macrophages, although their presence and contribution to ...

High-power slab-based Tm:YLF laser for in-band pumping of Ho:YAG

, 2008
Several remote sensing applications require pulsed sources in the mid-infrared spectral regime with high average powers and good beam quality. Ho:YAG lasers have a number of attractive features for high power generation at 2.1 microns, either for direct ...

The efficacy and optimal timing of pelvic floor muscle training for post‐prostatectomy incontinence in BPH patients: A systematic review

UroPrecision, EarlyView.
Abstract Surgical intervention for benign prostatic hyperplasia (BPH) can lead to postoperative stress urinary incontinence. Pelvic floor muscle exercises (PFME) are proposed as a non‐invasive strategy to mitigate symptoms, but their efficacy and optimal timing remain unclear.

Minimally invasive management of large seminal vesicle cyst in Zinner syndrome: Laser ablation for urinary retention

UroPrecision, EarlyView.
Abstract Background In Zinner syndrome (ZS), surgical intervention is recommended for pediatric patients with symptomatic disease. It is generally believed that cyst aspiration alone may lead to symptom recurrence. Although comprehensive surgical excision is often advocated to prevent recurrence, a combined approach of cyst aspiration and maximal cyst ...

The left ureterocele and stone of calyceal diverticulum in the patient with bilateral incomplete duplex kidneys managed by flexible ureteroscopy: a case report and literature review

BMC Urology, 2020
Background Duplex kidneys are one of the most common renal congenital abnormalities, mostly asymptomatic and of no clinical significance. There are little reports about the left ureterocele and stone of calyceal diverticulum in patients with bilateral ...
