Minimally Invasive Surgery for Kidney Stones

Extracorporeal Shock Wave Lithotripsy (ESWL)

Extracorporeal shock wave lithotripsy (ESWL) is a noninvasive outpatient treatment for small kidney stones utilizing a high voltage device that generates high-energy shock waves that enter the body through the skin surface without an incision. The shock waves are focused onto the stone and the stone is fragmented into particles, which can then be passed in the urine.

Dr. Mantu Gupta, Director of Mount Sinai's Kidney Stone Center has pioneered many of the methods and strategies currently used to determine who is a good candidate for ESWL and how to maximize effectiveness while improving patient safety.

Mount Sinai has a new state-of-the-art technologically advanced lithotripsy device located at the Mount Sinai Roosevelt Hospital location that is available five days a week for the expedient treatment of kidney stones in our patients.

Ureteroscopic Laser Lithotripsy (URSLL)

Ureteroscopic laser lithotripsy (URSLL) is a minimally invasive outpatient surgical technique that is completely endoscopic and uses natural body orifices to directly visualize and treat kidney stones located in the ureter or the kidney. A small endoscopic camera is passed through the urethra and urinary bladder into the ureter and/or kidney and then a Holmium:YAG laser is used to fragment the stone into particles that can be extracted from the body, so there is no need for the patient to pass them. Dr. Gupta has shown that the results for URSLL are superior to ESWL for stones in the upper part of the ureter that are larger than one cm. He also demonstrated that even morbidly obese patients can be treated with URSLL without compromising results.

We are fortunate at Mount Sinai to have endoscopes employing the latest digital technology and state-of-the-art Holmium laser machines. Dr. Gupta has tested and helped design many of the devices used today.
