BACKGROUND The erbium:yttrium scandium gallium garnet (Er:YSGG) laser differs from other laser techniques by having a faster and higher cure rate. Since the Er:YSGG laser causes an appropriate proportion of ablation and coagulation, it has advantages over the conventional carbon dioxide (CO2) laser and the erbium-doped yttrium aluminum garnet (Er:YAG) laser, including heating tendencies and exp...

We report a new technique for the rapid fabrication of microstripe cylindrical and toroidal mirrors with a high ratio (>10) of the two principal radii of curvature (RoC(1)/RoC(2)), and demonstrate their effectiveness as mode-selecting resonator mirrors for high-power planar waveguide lasers. In this process, the larger radius of curvature (RoC(1)) is determined by the planar or cylindrical shap...

Understanding the formation mechanism of SWNTs and endohedral metallofullerene is very interesting and also very important for the large-scale generation and controlled generation of various possible structures, such as different cage size and different metal species for metallofullerene and various radii and chiralities of SWNTs. Both endohedral metallofullerene and SWNTs are usually generated...

Purpose: Improvements to photoselective vaporization of the prostate (PVP) have been made over time, particularly with the introduction of higher power systems. Few studies however have compared the performance of these systems to their predecessors. The purpose of this study was to compare the clinical and perioperative outcomes of 80 W vs. 120 W PVP. Materials and Methods: A series of 267 and...

INTRODUCTION Photoselective laser vaporization of the prostate (PVP) is one of the most popular techniques of treatment of benign prostatic hyperplasia (BPH). The aim of this study was to assess the risk of thermal damage to the external urethral sphincter during PVP at distal part of prostatic urethra. MATERIAL AND METHODS 66 men submitted to PVP with 80-W Green Light Laser were randomly ass...

BACKGROUND A clinical evaluation of the use of a 980 nm diode laser in the treatment of bladder outlet obstruction secondary to benign prostatic hyperplasia (BPH), focused on perioperatory morbidity and results in a short-term follow-up. METHODS Fifteen patients were included in the study. All of them were evaluated by IPSS and Quality of Life (QoL) questionnaires, digital rectal examination,...

UNLABELLED Introduction The diode laser has been frequently used in the management of laryngeal disorders. The portability and functional diversity of this tool make it a reasonable alternative to conventional lasers. However, whether diode laser has been applied in transoral laser microsurgery, the ideal parameters, outcomes, and adverse effects remain unclear. Objective The main objective of ...

They state that “Alternative methods including electrocauterization and CO2 [carbon dioxide] laser, via vaporization improve hemostasis but result in scarring and poor cosmesis.” There is no citation for this statement, so I assume it represents the authors’ opinions. Although I am a big proponent of 4.0-MHz radiowave surgery, I also use the CO2 laser to treat rhinophyma (frequently concomitant...
