This laser uses a fiber that allows the tissue to be simultaneously cut and vaporized, allowing it to be used on large prostates.BPH tissue is cut into 2 or 3 pieces that, by use of a shredder, are separated into small pieces, which are later removed. The advantage of this technique is that patients who have received anticoagulant treatment and who have large prostates can be treated as in open surgery, but with much less bleeding and with a shorter time of hospitilization, between 1 and 2 days. This laser technique does not provide advantages in the treatment of smaller prostates over TUPR (transurethral prostate resection).
