INTRODUCTION The Thulium fiber laser may have several advantages over current urology lasers, including smaller size, more efficient operation, improved spatial beam quality, more precise tissue incision, and operation in pulsed or continuous-wave modes. Previous laser-tissue interaction studies utilizing the Thulium fiber laser have been limited to laser powers of less than 5 W, restricting po...

PURPOSE The prostate-specific antigen (PSA) level decreases after transurethral resection of the prostate (TURP). However, changes in the PSA level after potassium-titanyl-phosphate (KTP) laser vaporization of the prostate are not well known. The aim of this study was to investigate the effect of KTP laser vaporization of the prostate on PSA levels in patients with benign prostatic hyperplasia ...

OBJECTIVE In a series of cases of high-grade vaginal intraepithelial neoplasia (VaIN) at our institution, to analyze its clinicopathologic characteristics, diagnostic methodology, and therapeutic results obtained with the use of CO2 laser vaporization. MATERIALS AND METHODS Between January 2003 and December 2009, 28 patients with a diagnosis of high-grade VaIN were treated in our department u...

To investigate the factors that influence treatment satisfaction after high-power potassium-titanyl-phosphate (KTP) laser vaporization of the prostate, we compared the characteristics between patients who were satisfied and those who were not satisfied. In all, 97 patients aged between 53-82 years (median age 67 years) underwent high-power KTP laser vaporization of the prostate for lower urinar...

I. TECHNICAL PROGRESS The objective of this program was to seek improved process control and weldment reliability during laser welding of automotive aluminum alloys while retaining the high speed and accuracy of the laser beam welding process. In particular, we undertook a comprehensive experimental and theoretical research to understand the effects of various welding variables on the loss of a...

introduction: green light photo selective vaporization of the prostate (pvp) is a minimally invasive method of treatment for clinical benign prostatic hyperplasia with fewer side effects. the aim of this study is to evaluate the safety, effectiveness and cost analysis of pvp compared with transurethral resection of prostate. methods: a systematic search was done in cochrane, trip database, medl...

Perfluorocarbon (PFC) droplets were studied as new generation ultrasound contrast agents via acoustic or optical droplet vaporization (ADV or ODV). Little is known about the ODV irradiated vaporization mechanisms of PFC-microparticle complexs and the stability of the new bubbles produced. In this study, fluorescent perfluorohexane (PFH) poly(lactic-co-glycolic acid) (PLGA) particles were used a...

Two methods of preparing guanine in the gas phase, thermal vaporization and laser desorption, have been investigated. The guanine generated by each method is entrained in a molecular beam, single-photon ionized with tunable VUV synchrotron radiation, and analyzed using reflectron mass spectrometry. The recorded photoionization efficiency (PIE) curves show a dramatic difference for experiments p...

Introduction: The objective of this study was to evaluate the GreenLight Laser SimTM for resident education in a multi institutional study using a structured curriculum. Materials and Methods: Residents from two tertiary care hospitals participated in this study. The curriculum included four SIM modules and four SIM cases on the GreenLight Laser SimTM. Participants of various training levels we...
