GreenLight laser vaporization is a proven technique to treat benign prostate enlargement (prostate hyperplasia). The procedure is performed through the urethra under general anaesthetic and uses a high-efficiency laser to quickly and precisely vaporize the excess prostate tissue. As soon as the surgeon directs the laser beam to the prostate, the light pulses of the laser are absorbed by the prostate tissue. Within literally milliseconds, the temperature in the tissue or interstitial fluid is so high that the tissue is simply vaporized.
GreenLight laser vaporization of the prostate is an established alternative to the TURP procedure. Numerous scientific studies have shown that the effectiveness of the procedure is comparable to the transurethral resection (TUR) of the prostate. Because of the physical effect of the laser on the tissue, this also allows to safely operate patients needing strong blood-thinning medication. In addition, experienced surgeons such as those of the alta uro medical team can use this method to safely and effectively operate on patients with a prostate volume of more than 100 ml.
Scientific studies showed that there are fewer complications due to bleeding after a GreenLight laser vaporization of the prostate than after a TURP procedure. As the laser pulse both vaporizes the tissue and simultaneously scabs it, the risk of bleeding is very low indeed. Another advantage of the GreenLight laser is that patients taking blood thinners or with an elevated risk of bleeding may safely be operated on.
Currently, there is not yet as much data available on the use of the most recent laser generation than on TURP. Post-operative bleeding after surgery with a GreenLight laser can also occur, though the risk is much lower compared to the TURP procedure. Besides, there is a low risk of a narrowing of the urethra as a reaction to the operation and the ablated tissue may regrow, so that in rare cases another operation will be required after a certain time. The risk of involuntary loss of urine after laser vaporization is very low, too.
