This study compares the efficacy and ease of use of two methods to break up biliary stones. Electrohydraulic lithotripsy uses an electric spark, and the laser system uses light to create shock waves that break up the stones.

Gallstone disease affects over 20 million Americans. Among patients with gallbladder disease, the prevalence of choledocholithiasis (stones in the bile duct) is estimated to be 10-20%. End...
to assess safety, efficacy of Flexible ureteroscopy (FURS) holmium:YAG laser lithotripsy (LL) compared to extracorporeal shockwave lithotripsy (ESWL) in management of lower calyceal stones...
The purpose of this study is to study the outcome of patients after ureteroscopy in which all fragments remaining after holmium laser lithotripsy were retrieved compared to those where sma...
The purpose of this study is to compare the need to use mechanical lithotripsy between patients undergoing POC-LL and EBS for removal of difficult bile duct stones
Very large bile duct stones are difficult to remove. Dilation-assisted stone extraction, also termed small endoscopic sphincterotomy plus endoscopic papillary large balloon dilatation, is ...
Bile duct stones >1 cm have a decreased incidence of successful endoscopic extraction and often require lithotripsy. Although prior guidelines suggested mechanical lithotripsy for large CBD stones, cu...
The safety and efficacy of the combination of electronic choledochoscopy and holmium laser lithotripsy for complicated bile duct stones were assessed. In total, 20 patients participated in this study,...

Difficult and large common bile duct stones can be crushed and removed using a mechanical lithotripter. Very often the lack of working space within the common bile duct causing the failure of mechanic...
The destruction of a calculus of the kidney, ureter, bladder, or gallbladder by physical forces, including crushing with a lithotriptor through a catheter. Focused percutaneous ultrasound and focused hydraulic shock waves may be used without surgery. Lithotripsy does not include the dissolving of stones by acids or litholysis. Lithotripsy by laser is LITHOTRIPSY, LASER.
Fragmentation of CALCULI, notably urinary or biliary, by LASER.
A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as in LASER THERAPY. These non-thermal effects are thought to be mediated by a photochemical reaction that alters CELL MEMBRANE PERMEABILITY, leading to increased mRNA synthesis and CELL PROLIFERATION. Low-level laser therapy has been used for a wide variety of conditions, but most frequently for wound healing and pain control.
