Methods and devices for internal tissue removal by means of laser energy are provided. In a preferred embodiment, a method for internal tissue removal in which tissue is removed in the form of fluid (liquid, vapor), solid debris and/or a combination of these is provided. Other embodiments disclose a method and a photodynamic method for the treatment of urological disorders such as benign prostatic hyperplasia. In another embodiment, a treatment system comprises infusion and vacuum hoses, a laser energy source with a wavelength or wavelength combinations for higher tissue ablation rates as well as reduced bleeding. As an advantageous feature, this invention can be applied to any kind of soft tissue which needs to be removed from the body. In addition, as it is not limited to hollow organs, it can be performed with or without using an endoscope.
