Laser treatment of benign prostatic hypertrophy

A method of treating benign prostatic hyperplasia in a patient in need of said treatment, comprising the following steps:

• trans-perineally introducing at least one laser energy delivery fiber through a perineal area of the patient in a first position in a prostate of the patient, wherein the laser energy delivery fiber has a laser emitting fiber tip;
• delivering laser energy from a laser source through the laser emitting fiber tip to a first volume of prostrate tissue placed in front of the laser emitting fiber tip, until said first volume is vaporized or sublimated and a cavity is formed in the prostate tissue;
• pulling back the laser energy delivery fiber from the first position to a second position;
• delivering energy from the laser energy source through the laser emitting fiber tip to a second volume of prostate tissue placed in front of the laser emitting fiber tip while the laser energy delivery fiber is in the second position, until said second volume is vaporized or sublimated and the cavity is enlarged;
• removing the laser energy delivery fiber from the prostate;
• and
• reducing the volume of the cavity such that compression of the urethra by prostate tissue surrounding the urethra is relieved.
