Z. Naturforsch. 53 b, 900-902 (1998); eingegangen am 9. April 1998 Holmium Sesquiselenide, Chemical Transport, Crystal Structure Starting from HoSe2_ t powder and holmium metal bright brownish-yellow, plate-like single crystals of Ho2Se3 could be prepared by chemical transport with A1C13. Holmium sesquiselenide crystallizes in the Sc2S3-type structure, space group Fddd, with lattice constants a...

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...

A 21-year-old man presented with an enlarged giant hemangioma on glans penis which also causes an erectile dysfunction (ED) that partially responded to the intracavernous injection stimulation test. Although the findings in magnetic resonance imaging (MRI) indicated a glandular hemangioma, penile colored Doppler ultrasound revealed an invaded cavernausal hemangioma to the glans. Surgical excisi...
