1. A method of treating prostatic tissue in a patient affected by a prostate disease, the method comprising the following steps:
trans-perineally introducing at least one energy delivery device reaching at least a first position in one prostate lobe requiring treatment, wherein the at least one energy delivery device comprises at least one frontal-emission optical fiber;
delivering laser energy from a laser source through the frontal-emission optical fiber to a first volume of tissue of said prostate, said first volume being in front of a tip of said frontal-emission optical fiber, until said first volume is vaporized or sublimated and a cavity is formed in the prostate tissue;
(a) pulling back the energy delivery device from the first position to a second position;
(b) delivering energy from the energy source through the energy delivery device to a second volume of tissue of said prostate while the energy delivery device is in the second position, until said second volume is vaporized or sublimated and the cavity is enlarged;
(c) repeating steps (a) and (b), if needed;
removing the energy delivery device from the prostate.
