1. A method of inducing a urethral enlargement at the prostate in an operative field in a patient, which includes a periurethral region of the prostate, comprising the steps of:

  • inserting an electrode into the urethra through the penis to a region of the prostate within the operative field without piercing the wall of the urethra; and

    applying an appropriate level of a high-frequency output from a high-frequency generator through the electrode to induce heat ablation of at least a portion of the urethra and at least a portion of the periurethral tissue within the operative field, thereby inducing formation of a cavity to enlarge a passageway within the urethra.
