Enlarged Prostate: Laser Therapies
Several laser methods for treating an enlarged prostate gland (Reference benign prostatic hyperplasia, or BPH Opens New Window) are now being used. Laser therapy uses a laser beam to remove the part of the prostate that is blocking the Reference urethra Opens New Window. The procedure is done under either a Reference general Opens New Window or Reference spinal Opens New Window anesthetic. Most men who have laser treatment of BPH are able to leave the hospital the same or the next day.
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 days.
- With vaporization, a channel is immediately opened, allowing the free flow of urine.
Studies comparing laser methods with transurethral resection of the prostate (Reference TURP Opens New Window) have found that:
- Laser therapies improve symptoms about the same as TURP.Reference 1, Reference 2
- Laser therapies improve quality of life about as well as TURP.Reference 3
- Compared to men who have TURP, men who have a laser therapy have a shorter hospital stay.Reference 4
- Men who have a laser therapy need to have another treatment more often than men who have TURP.Reference 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 Reference urinary catheter Opens New Window, 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 hospitals.
