1. A method for treating benign prostatic hyperplasia (BPH), comprising the steps of:
- positioning an energy-emitting section of a needle in a plurality of locations in a prostate lobe adjacent the prostatic urethra; and
delivering energy at each location for less than 30 seconds to thereby confine thermal ablation to lobe tissue adjacent the prostatic urethra and preventing thermal diffusion to peripheral lobe tissue.

Abstract
A vapor delivery needle is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the needle can ablate a continuous lobe region in the prostate parallel to the urethral wall. Another feature of the vapor delivery needle is that it can introduce a cooling fluid into the urethra during treatment. Methods associated with use of the energy delivery probe are also covered.
