In the present study, the clinical effects of flexible ureteroscopy lithotripsy (FURL) and percutaneous nephrolithotomy (PCNL) for the treatment of kidney stones of ≤2 cm was studied. Seventy-two patients with kidney stones were randomly divided into the FURL group (n=39) under ureteroscope lithotripsy with holmium laser and PCNL group (n=33) under PCNL with holmium laser and compared their cli...

We report the direct observation of slow fluctuations of helical antiferromagnetic domains in an ultrathin holmium film using coherent resonant magnetic x-ray scattering. We observe a gradual increase of the fluctuations in the speckle pattern with increasing temperature, while at the same time a static contribution to the speckle pattern remains. This finding indicates that domain-wall fluctua...

A novel 2-D coordination polymer constructed from high nuclearity nanosized Ho48 clusters was synthesised and structurally characterized using single-crystal X-ray analysis. The Ho48 cluster core with a charming waist drum-like structure was templated by CO3(2-) ions, and bridged by Ho-N bonds to get a 2-D coordination polymer.

BACKGROUND There are many options for urologists to treat ureteral stones that range from 8 mm to 15 mm, including ESWL and ureteroscopic holmium laser lithotripsy. While both ESWL and ureteroscopy are effective and minimally invasive procedures, there is still controversy over which one is more suitable for ureteral stones. OBJECTIVE To perform a retrospective study to compare the efficiency...

BACKGROUND In vitro experiments have shown that holmium laser energy can effectively ablate even calcified plaque in human arterial vessels. Because high-energy densities from holmium lasers can easily be transmitted through quartz fibers, this solid-state laser has been suggested as an alternative intraluminal treatment of atherosclerotic plaque. METHODS AND RESULTS To develop an intimal pla...

It is estimated that by 2050 there will be 2 billion people aged 60 years and older in the world. The evidence base for the health benefits of good nutrition and physical activity, as well as weight loss among overweight and obese adults, is growing and a number of policies and guidelines are available to guide health professionals in serving older people at various stages of the lifecycle. The...

introduction: the aim of this study is to compare holmium laser (ll) with pneumatic lithoclast (pl) in patients with upper ureteral stones and their ability to destruct the stones and making the patient stone free. we also compare the duration of these procedures and their complications, such as urosepsis, perforation, and pushing the stone backward. methods: this has been a clinical randomized...
