While several laser methods are used, in general they all either sear
(laser ablation) or vaporize (laser vaporization) the prostate tissue.
As the seared tissue heals, it shrinks, dead
tissue falls off, and the blockage is reduced. This may require several
With vaporization, a channel is immediately opened, allowing
the free flow of urine.
Studies comparing laser methods with transurethral resection
of the prostate (TURP) have found that:
Laser therapies improve symptoms about the same as TURP.1, 2
Laser therapies improve quality of life about as well as TURP.3
Compared to men who have TURP, men who have a laser therapy have a shorter hospital stay.4
Men who have a laser therapy need to have another treatment more often than men who have TURP.3
Other things to think about include the following:
Some men may choose laser therapy because of the shorter hospital
stay, shorter time with a urinary catheter, and lower risk of complications. But discomfort during urination
lasts longer after laser surgery.
Laser therapies are newer than other treatments for BPH, so there isn't as much evidence on long-term results. Men who have laser therapy for BPH may be more likely to need another treatment than men who have an older treatment, like transurethral resection of the prostate (TURP).
Prostate surgery using a laser may not be available in all
