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.

Intracorporeal lithotripsy with the Alexandrite laser
Lasers in Surgery and Medicine, 1997The objective of this study was to evaluate clinical use of an Alexandrite laser lithotripter for intracorporeal lithotripsy of urinary calculi.We prospectively evaluated a flash lamp pumped, Q-switched Alexandrite solid-state laser for use in conjunction with ureteroscopy (30 cases) or percutaneous nephrolithotripsy (2 cases).

In vitro Lithotripsy with the Alexandrite Laser
European Urology, 1992The Alexandrite laser system has proven to be an effective and safe method of ureteral lithotripsy. Some authors have recently reported the risk of interspersion of fiber splinters into tissue during lithotripsy, when short pulses and high power densities are employed.

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.

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.

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.
