urethroscopic holmium: yag laser ablation of large urethral stone after two-stage urethroplasty
hairball in a urethral diverticulum has rarely been reported. these hairballs are usually formed in the diverticulum coated with a hair bearing epithelium and can lead to urinary obstruction or infection. using laser is a safe way to ablate such stones.
متن کاملHolmium-YAG laser for gall stone fragmentation: an endoscopic tool.
A systematic review of the 2.1 mu holmium-YAG laser for gall stone lithotripsy was undertaken. This infrared laser, which can be used endoscopically and percutaneously, has safety advantages over other lasers and has potential as a general purpose vascular and surgical tool. Twenty nine gall stones (mean mass 1.3 g) were fragmented in vitro using pulse energies of 114 to 159 mJ/pulse at 5 Hz wi...
متن کاملStudy of laser ablation using nano-second laser pulses
In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...
متن کاملPercutaneous transhepatic holmium laser lithotripsy of a large common bile duct stone
A 58-year-old woman presented with a 4 cm obstructing choledocolith within the proximal common bile duct. She had an extensive operative history resulting in common bile duct to jejunum anastomosis after cholecystectomy. Endoscopic retrograde cholangiopancreatography (ERCP) removal was unsuccessful, and surgical exploration was contraindicated due to multiple comorbidities. Interventional radio...
متن کاملA Comparison of Holmium YAG Laser and Electrokinetic Lithotripter in Pediatric Ureteral Stone Treatment
Background: We evaluated endoscopic treatment of ureter stones with a holmium: yttrium-aluminum-garnet laser (Ho: YAG) lithotripter and an electrokinetic lithotripter (EKL) in children. Methods: Patients with ureteral stones, admitted to the pediatric surgery department of our hospital between November 2011 and January 2015, were evaluated retrospectively. Demographic data, initial symptoms, ag...
