The article describes the diverse methods of stone destruction in urolithiasis patients, including laser lithotripsy as the least traumatic and most efficient method of demolition of all types of urinary stones. Different types of lasers for intracorporeal lithotripsy have different mechanisms of stone fragmentation depending on the type of laser and ...

Current Opinion in Urology, 2002
All literature related to laser lithotripsy published within the past year was reviewed. Salient articles have been reviewed and grouped according to safety issues, efficacy, comparison studies, biliary applications or future directions.There is no evidence of renal deterioration after holmium:yttrium-aluminium-garnet lithotripsy.

Pulsed lasers and endocorporeal laser lithotripsy
Progrès en Urologie, 2021Endocorporeal laser lithotripsy (ELL) is currently the gold standard for the treatment of renal stones during retrograde intra-renal surgery (RIRS). The newly-authorised thulium fibre laser (Tm-Fibre) in now evaluated as a holmium:yttrium-aluminium-garnet (Ho:YAG) laser alternative, which is the most well-known laser source for ELL.

Holmium:YAG lithotripsy of uric acid calculi produces cyanide. The laser and stone parameters required to produce cyanide are poorly defined. In this study, we tested the hypotheses that cyanide production: (1) varies with holmium:YAG power settings; (2) varies among holmium:YAG, pulsed-dye, and alexandrite lasers; and (3) occurs during holmium:YAG ...

The high cost of laser equipment and the required specialization of staff members make extension of laser lithotripsy to every hospital impractical. At present, in Ontario, laser lithotripsy is available only in Toronto and Kingston, and ESWL is available only in Toronto and London.

Surgical Clinics of North America, 1992
Laser lithotripsy is an excellent method of fragmenting those biliary stones that cannot be removed easily by less technically advanced methods such as basket extraction. The energy can be delivered through fine flexible fibers, around 200 to 320 microns in diameter, that can be passed through the channels of a variety of small endoscopes.

Electrohydraulic Lithotripsy and Laser Lithotripsy
2017Mechanical lithotripsy is usually employed for the fragmentation of large common bile duct (CBD) stones. However, refractory CBD stones, stones larger than 2 cm in size, those firmly impacted, those located above a bile duct stricture, and those located in the intrahepatic bile duct, or cases of Mirizzi syndrome are difficult to treat.

Laser-assisted lithotripsy is a minimally-invasive method for destroying or disruption of human urinary stones. For this purpose laser light delivered through the flexible sealed waveguide or fibre could be utilized. On the output end of the delivery system the laser ligth is focused onto the surface of urinary stones with various size and various ...

Gastrointestinal Endoscopy Clinics of North America, 1993
The surgical treatment of choledocholithiasis has traditionally relied on the exploration of the common bile duct. The advent of laparoscopic cholecystectomy now permits the surgeon direct access to the common bile duct. Currently, one fourth to one third of all cholecystectomies are performed through the laparoscope.

Erbium: YAG laser Lithotripsy Mechanism
Journal of Urology, 2002We tested the hypothesis that the mechanism of long pulse erbium:YAG laser lithotripsy is photothermal.Human urinary calculi were placed in deionized water and irradiated with erbium:YAG laser energy delivered through a sapphire optical fiber. Erbium:YAG bubble dynamics were visualized with Schlieren flash photography and correlated to acoustic ...
