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 ...

Endoscopic lithotripsy with the holmium:YAG laser
Lasers in Surgery and Medicine, 1999The holmium:YAG (Ho:YAG) laser can be used not only for soft tissue but also for hard tissue such as urinary calculi. The objective of this study was to assess the usefulness of the Ho:YAG laser for endoscopic lithotripsy in patients with urinary tract stone.

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.

Pulsed Thulium:YAG Laser for Lithotripsy
European Urology FocusPulsed thulium:YAG (p-Tm:YAG) laser is a novel technology for lithotripsy that seems to be positioned favorably in the middle ground between Ho:YAG laser and thulium fiber laser. This mini review summarizes current evidence regarding p-Tm:YAG physical properties, laboratory results, and clinical outcomes.

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.

Techniques of Laser Lithotripsy
Journal of Endourology, 1988A tunable pulsed dye laser has been used for the treatment of 157 patients with renal and ureteral calculi. All calculi treated were too large to be extracted by ureteroscopy or were not appropriate candidates for ESWL. In 106 cases, the stone was completely fragmented with the laser. The laser was used in combination with ESWL in 34 cases.

[Ureteroscopic lithotripsy using the laser].
Annales d'urologie, 1997The Cagliari urology team is very satisfied with the use of the dye laser for ureteroscopic lithotripsy. This apparatus is recommended in units possessing a well equipped endourology room, otherwise it is simpler to use endoureteric ballistic lithotripsy, which also provides good results.

This chapter provides an in-depth summary of the application of the holmium:YAG laser in ureteroscopy. First, the basic physics of laser lithotripsy is reviewed. Laser generators and the peculiarities of laser fibers are then discussed, with a special focus on their application in flexible ureteroscopy.

The application of lasers for use in the treatment of kidney stones is among the most important developments in the specialty of urology in the last 50 years. As kidney stone prevalence continues to rise from an estimated 5.2% in 1994 to 8.8% in 2012, the importance of the development and evolution of laser technology cannot be understated [1].
