INTRODUCTION: The holmium laser has revolutionized the practice of minimally invasive endoscopy for kidney stones. Recently, a novel, rigid hand-piece for use in percutaneous nephrolithotomy (PCNL) that couples the holmium laser with suction has been developed. To date, there exists limited data regarding the usability and ergonomics of such treatment systems. We thus sought to compare surgeon-rated usability with three different suction laser hand-pieces in a porcine model. METHODS: We performed bilateral reverse PCNL on 4 female domestic farm pigs...

INTRODUCTION: Shock wave lithotripsy (SWL) is the treatment of choice for most cases of renal lithiasis in children. Some cases, however, are refractory to SWL and may be associated with anatomic and metabolic changes or a large stone burden. In these circumstances, mini-percutaneous nephrolithotomy (mini-PCNL) is an option. OBJECTIVE: The aim was to assess the safety and efficacy of high-power holmium YAG (Ho:YAG) laser in mini-PCNL for staghorn calculi. PATIENTS AND METHODS: The clinical records relating to 35 mini-PCNLs (Table) performed between January 2008 and December 2012 in 33 patients (27 boys and 6 girls; mean age 7 years, range 2-18 years) were retrospectively reviewed...

BACKGROUND AND OBJECTIVE: Fractional Photothermolysis (FP) is a method of skin treatment that generates a thermal damage pattern consisting of multiple columns of thermal damage, also known as microscopic treatment zones (MTZs). They are very small in diameter and are generated by application of highly focused laser beams. In order to obtain the smallest spot size, the treatment should be performed in the focal plane. Any deviation from the focal plane (DFP) results in an increase of spot size...

BACKGROUND: Ablative fractional laser procedures have been shown to facilitate topical drug delivery into the skin. Past studies have mainly used ex vivo models to demonstrate enhanced drug delivery and in vivo studies have investigated laser created channels over a time course of days and weeks rather than within the first few minutes and hours after exposures. We have noticed rapid in vivo fibrin plug formation within ablative fractional laser lesions impairing passage through the laser created channels...

BACKGROUND: Facial aging is a natural biological process with symptoms such as sagging tissue, accentuated lines, furrows, wrinkles, dyschromias, and loss of facial volume. Rhytidectomy alone often fails to achieve a patient's expected goals, which is why there is a high demand for adjunct laser skin treatment. METHODS: From January 2007 to February 2013, a total of 80 patients with skin types Fitzpatrick I-IV underwent large undermined cutaneous flap rhytidectomy and superficial muscular aponeurotic system (SMAS) plicature plus hyaluronic acid injection on the nasolabial folds and lips and concomitant Lumenis UltraPulse CO2 Active FX total ablation mode resurfacing of nonundermined skin...

BACKGROUND: Aberrant Mongolian spots (AMS) distal to the lumbosacral region are thought to be more likely to persist than typical sacral Mongolian spots. So far, Q-switched ruby laser (QSRL) has been the treatment of choice for AMS. Intense pulsed light (IPL) is obtained from flashlamp devices that emit wavelengths between 515 and 1200 nm. IPL has documented efficacy for the treatment of irregular pigmentation, telangiectasia, rough skin texture, rhytids, hair removal, and vascular lesions, with several filters being available that can be used to block shorter wavelengths from the skin...
