GreenLight Laser
Blood loss used to be an issue during urological surgery. Patients typically
spent days in the hospital waiting for bleeding to subside. Today, Kaweah
Delta offers the new GreenLight™ laser surgery system.
“The laser is so hot, it actually seals the blood vessels as the
procedure is performed,” said Dr. Marty Prah, who along with Joseph
Chidi, MD, and Tu-Hi Hong, MD, use the GreenLight™ at Kaweah Delta.
The GreenLight™ laser system is the cornerstone of Kaweah Delta’s
new Endourology Suite—the most advanced in the region, according
to Dr. Prah.
Benefits of GreenLight Laser Therapy
- Removes obstructing prosthetic tissue in a virtually bloodless procedure.
- Most patients are released from the hospital within a few hours of the
procedure and return home without a catheter, returning to normal non-strenuous
activity within days.
- Offers rapid symptom relief and improvement in urine flow.
- Minimizes many of the side effects of other procedures.

How does GreenLight XPS work?
The powerful, state-of-the-art GreenLight XPS Laser vaporizes excess prostate
tissue using laser energy. A thin fiber is inserted into urethra through
a cystocope. The fiber, under direct vision, delivers the laser energy
that precisely vaporizes and destroys the tissue blockage that obstructs
the passage of urine. The physician is able to safely view and control
the treatment area. Greenlight Laser therapy is covered by Medicare and
most private insurers.
