EHL offers an effective and safe solution for various gallbladder and biliary stones, enhancing patient safety, treatment outcomes, and operational simplicity—making it an excellent choice for treating refractory cases.
Percutaneous Transhepatic Cholangioscopic Lithotripsy
Endoscopic retrograde cholangiopancreatography
T-tube Cholangiostomy for Common Bile Duct Stone Management
EHL minimizes tissue damage due to its shockwave energy being focused on the stone’s surface and rapidly dissipating with distance. The shockwaves are delivered in short pulses, reducing heat and mechanical stress. Combined with precise endoscopic guidance, it effectively prevents excessive energy from affecting surrounding healthy tissues, significantly lowering the risk of damage.
The electrode emits an electrical pulse, breaking the molecular bonds between sodium and chloride ions in the surrounding saline. This reaction generates powerful shock waves that rapidly fragment the stone
