Comprehensive studies show that the holmium laser is ideal for treating BPH. Holmium laser treatments have been the most rigorously investigated BPH techniques. Over 90 articles have been published from 8 randomized clinical trials and over 30 case studies and comparative series. The American, European, British and Australasian urology associations recommend holmium laser for BPH treatment. Hol...

In this presented work, pure and holmium, niobium, holmium–niobium co-doped titanium dioxide nanopowders were synthesized by the sol–gel method. Their morphological, structural, optical, photocatalytic properties analyzed scanning electron microscopy, X-ray diffraction, UV–visible spectrophotometer. The activities of examined using ultraviolet light. results have shown that doping both with a s...

The absorption spectra of the 4f electron transitions of neodymium, praseodymium, holmium and erbium complexes with fleroxacin in the presence of cetylpyridinium chloride were studied by normal and derivative spectrophotometry. Their molar absorptivity at the maximum absorption bands are about 5.3 (at 571 nm) times greater for neodymium, 2.8 (at 483 nm) times greater for praseodymium, 12.6 (at ...

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 ...

PURPOSE Long-segment urethral strictures (LSUS) are refractory to urethrotomy and urethroplasty. Holmium laser urethrotomy has shown favorable therapeutic outcomes in short-segment urethral stricture. We therefore evaluated the therapeutic effectiveness and safety of holmium laser endourethrotomy in the treatment of LSUS. MATERIALS AND METHODS Holmium laser endourethrotomy was used to treat 1...

Holmium laser resection of the prostate (HoLRP) was first described by Gilling et al in 1995. HoLRP has now evolved into holmium laser enucleation of the prostate (HoLEP) with the advent of the intravesical soft-tissue morcellator. The procedure involves anatomical dissection of the prostatic tissue off the surgical capsule in a retrograde fashion using a high-powered holmium laser followed by ...

The resonant pumping of holmium fibre lasers provides a fibre laser platform capable of addressing a wide range of applications that benefit from operation at wavelengths beyond 2.1 μm. This architecture can provide laser devices that promise high efficiency sources in the 2.1 μm spectral region with excellent beam quality and power scalability. This paper presents our recent results of resonan...

Background: Among various intracorporeal lithotripters, pneumatic lithotripter has become the widely used tool for the treatment of urinary stones. Recently the holmium: YAG laser has been used with a wide range of potential urological applications, including intracorporeal lithotripsy of urinary calculi. Purpose: Compare the effectiveness and complications of treatment for ureteric stones betw...

The treatment and relapse rate of genital warts are significant problems. The aim of this observational study was to assess the efficacy of holmium laser treatment of genital warts. A total of 1500 outpatients with genital human papillomavirus-induced lesions presenting from August 2002 to June 2005 were treated with holmium laser. The effects and side-effects of treatment were observed and ana...
