This is a prospective study to assess a complementary treatment for genital warts after laser vaporization. 62 patients were enrolled in two randomized groups: Al: laser vaporization alone. A2: laser vaporization, followed with Pidotimod plus vitamin C for 2 1/2 months. The latter treatment shortened the time of warts remission and marginally decreased the rate of the warts' recurrence: 81% ver...

introduction: laser-assisted vaporization of prostate tissue by means of the potassiumtitanyl- phosphate (ktp) laser is in clinical use. alternative laser sources are available but are lacking clinical experience.the 980 nm wavelength diode laser provides good hemostasis, in addition to a more rapid ablation rate. the aim of this study is approving the capability, feasibility, and good post-ope...

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 ...

INTRODUCTION Transurethral resection of the prostate (TURP) is still considered the gold standard to treat benign prostatic hyperplasia (BPH). However, photoselective vaporization of the prostate (PVP) has gained widespread acceptance as an alternative option requiring preoperative patient selection. Four laser systems are currently in use: holmium, thulium, diode and GreenLight. MATERIALS AN...

PURPOSE Absorption of irrigation fluid was not detected during GreenLight™ laser vaporization of the prostate using the first generation 80 W laser. However, data are lacking on intraoperative irrigation fluid absorption using the second generation 120 W high power laser. We assessed whether fluid absorption occurs during high power laser vaporization of the prostate. MATERIALS AND METHODS We...

Micron-sized liquid perfluorocarbon (PFC) droplets are currently being investigated as activatable agents for medical imaging and cancer therapy. After injection into the bloodstream, superheated PFC droplets can be vaporized to a gas phase for ultrasound imaging, or for cancer therapy via targeted drug delivery and vessel occlusion. Droplet vaporization has been previously demonstrated using a...

Single aerosol particles of ethylene glycol and oleic acid are vaporized on a heater at temperatures between 500 and 700 K, and the resulting vapor plume is ionized by a 10.5-eV vacuum ultraviolet (VUV) laser. The mass spectra are compared to those obtained by CO2 laser vaporization followed by VUV laser ionization. The relative intensities of the parent and fragment ion peaks are remarkably si...

The translating and rotating rod or disk of a conventional laser vaporization cluster source is replaced by a liquid metal target. The self-regenerating liquid surface prevents cavities from being bored into the sample by laser ablation. The laser beam strikes a near pristine surface with each pulse, resulting in signals with much better short and long term stabilities. While this approach cann...

A systematic review was undertaken to determine whether coagulation or laser vaporization of endometriomas is associated with an increase in the risk of cyst recurrence compared with excision of the pseudocapsule. In the four comparative trials identified, endometrioma recurrence was reported in 39 of 212 (18.4%) women treated with coagulation or laser vaporization compared with 19 of 295 (6.4%...

PURPOSE To assess the prevalence and extent of irrigation fluid absorption during thulium laser vaporization of the prostate. MATERIAL AND METHODS Fifty-four patients undergoing thulium laser vaporization of the prostate were prospectively included into the trial at a tertiary referral center. Isotonic saline containing 1% ethanol was used for intraoperative irrigation. Absorption of irrigati...
