It’s estimated that nearly 2 million patients visit their doctors or local emergency rooms because of kidney stones every year.1 Some stones become so large they cause obstruction in the kidney, ureter and bladder requiring surgical removal. If needed, lithotripsy or other surgical techniques may be used for stones which do not pass through the ureter or bladder on their own.

Electrohydraulic Lithotripsy (EHL) is primarily used in endoscopic procedures to fragment large and difficult urological (kidney, urinary, bladder) stones. EHL provides a treatment option for endourologist with expertise in endoscopic management of urological stones. Using an ureteroscope or cystoscope with a disposable probe, the urologist can locate and fragment the stone(s) quickly.


About 15% of all people with gallstones will have gallstones in the bile duct, or choledocholithiasis, according to research published in The Medical Clinics of North America.

The stone location is clearly visible within the saline filled endoscopic field using a direct visualization scope. Gastroenterologists can customize the probe power output as well as the number of pulses delivered per foot-pedal depression. This improved technology should help decrease procedure times and may help to fragment harder stones. Also, the AUTOLITH® Touch LCD screen will track the probe life based on pulse shot counts.


Use robust and reliable high flow CO2 insufflation systems to provide greater patient safety during laparoscopic procedures and make the peritoneal environment better for both patients and surgeons.


Improve scope insertions and see more clearly for increased precision during urologic and arthroscopic procedures with cost-effective endoscopic fluid management devices that offer hands-free fluid delivery. Northgate Technologies fluid management devices give physicians the power to take control of irrigation pressures during endoscopic procedures utilizing gravity fluid-flow.
