PURPOSE We report on the first randomized trial to our knowledge comparing holmium laser ablation and photoselective vaporization of the prostate in patients with a small to moderate size prostate. MATERIALS AND METHODS Between March 2005 and April 2007, 109 patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia and prostate size 60 cc or smaller were randomized ...

Direct fabrication of microelectrodes on a polymer substrate using selective ultrashort pulsed laser ablation of inkjet-printed Ag lines" (2012). An inkjet-based ultrashort pulsed laser patterning on a polymer substrate is presented with high-laser scanning speeds. The effects of the laser processing parameters on the ablation characteristics were studied to accomplish damage-free laser ablatio...

BACKGROUND Endoluminal laser ablation is now considered the method of choice for treating greater saphenous vein insufficiency. General anesthesia and peripheral nerve blocks with sedation have the risk of post-procedural delay in discharge and prolonged immobilization with the risk of deep vein thrombosis. The main pain experienced by patients during the procedure is during the laser ablation ...

Laser parameters, typically wavelength, pulse width, irradiance, repetition rate, and pulse energy, are critical parameters which influence the laser ablation process and thereby influence the LA-ICP-MS signal. In recent times, femtosecond laser ablation has gained popularity owing to the reduction in fractionation related issues and improved analytical performance which can provide matrix-inde...

BACKGROUND The goal of this retrospective cohort study (REVATA) was to determine the site, source, and contributory factors of varicose vein recurrence after radiofrequency (RF) and laser ablation. METHODS Seven centers enrolled patients into the study over a 1-year period. All patients underwent previous thermal ablation of the great saphenous vein (GSV), small saphenous vein (SSV), or anter...

PURPOSE To evaluate percutaneous laser ablation in treating benign thyroid nodules, we conducted a meta-analysis based on summarizing existing researches. MATERIALS AND METHODS A literature search for clinical trial was performed in PubMed, Cochrane Library and Excerpt Medica Database. The qualities of included studies were evaluated. We calculated the indexes with mean difference. Heterogene...

Acne keloidalis nuchae (AKN) is a disease of unclear etiology that mainly affects males. Medical treatment of AKN is difficult, with refractory cases often requiring ablation by laser or surgical resection. We report herein, a 23-year-old male with refractory AKN treated successfully with combined laser ablation, using an 810-nm diode laser and a 1064-nm Nd:YAG laser.

The threshold for explosive vaporization of a liquid layer on an opaque solid surface heated by an ultraviolet excimer pulsed laser is studied by a photoacoustic probe-beam deflection method. The probe beam traverses the liquid in the vicinity of the laser-heated liquid-solid interface. Below the explosion threshold, photoacoustic generation in the solid occurs only through a thermoelastic mech...

Evolving research has demonstrated that surgical cytoreduction of a high-grade glial neoplasm is an important factor in improving the prognosis of these difficult tumors. Recent advances in intraoperative imaging have spurred the use of stereotactic laser ablation (laser interstitial thermal therapy [LITT]) for intracranial lesions. Among other targets, laser ablation has been used in the focal...

Laser axotomy followed by time-lapse microscopy is a sensitive assay for axon regeneration phenotypes in C. elegans(1). The main difficulty of this assay is the perceived cost ($25-100K) and technical expertise required for implementing a laser ablation system(2,3). However, solid-state pulse lasers of modest costs (<$10K) can provide robust performance for laser ablation in transparent prepara...
