Transurethral resection of the prostate (TURP) is a surgical procedure for relief of BPH. In this procedure an instrument is inserted through the penis and into the urethra to remove some of the prostate tissue.
Transurethral laser surgery is more commonly performed now than TURP. There are three different laser procedures:
Photoselective vaporization of the prostate (PVP). A laser is used to melt away (vaporize) excess prostate tissue to open the urinary channel.
Holmium laser ablation of the prostate (HoLAP). This is a similar procedure to PVP, except that a different type of laser is used to melt away (vaporize) the excess prostate tissue.
Holmium laser enucleation of the prostate (HoLEP). The laser is used to cut and remove the excess tissue that is blocking the urethra. Another instrument, called a morcellator, is then used to chop the prostate tissue into small pieces that are easily removed.
