Photoselective vaporization of the prostate with GreenLight laser

The use of laser technology has become widespread in urology for the treatment of BHP (benign prostatic hyperplasia). Among the different methods that use laser for this purpose, the most popular and efficient is the so called photoselective vaporization of the prostate with GreenLight laser.In this procedure laser beam is used to remove excess prostatic tissue with the aim to enlarge that part of the urethra which goes through the prostate to facilitate the easy flow of urine there. The laser beam used is selectively absorbed by the blood inside the prostate. This operation can be used on all affected men by BPH who do not respond to appropriate drug treatment. This therapy is particularly advantageous for patients who are on anticoagulant as they won’t need to interrupt their medication.

Other procedures are also available for the treatment of BPH such as transurethral resection of prostate (TURP) and ‘open-sky’ transvesical adenectomy. However, laser treatment incurs less complications and more advantages for the follolwing reasons:

  1. Minor risk of bleeding
  2. No need to interrupt anticoagulant therapies
  3. Short term hospitalisation (possibly day case surgery)
  4. Quicker recovery
  5. Less than 24 hrs catherisation
  6. Immediate results: the improvement of urinary symptoms is instantaneous

GreenLight laser uses powerful specific beam which is particularly absorbed by blood in the relevant tissues. The specific energy absorption results in overheating the target tissue and its consequent evaporation. In addition the GreenLight laser beam has considerable anticoagulant power which ensure less bleeding than a TURP procedure.
