ABSTRACT:
Novel methods for the chemical ablation of tissue (e.g. prostatic tissue) are described. These methods include the steps of: (a) providing one or more solid salt dosage forms comprising 50-100% w/w salt; and (b) inserting one or more of such solid salt dosage forms into the tissue. The solid salt dosage forms is optionally inserted into the tissue under real-time ultrasonic observation. An advantage of the present invention is its ability to eliminate toxic byproducts. For example, where NaCl-based solid salt dosage forms are used to effect localized chemical ablation, the concentration is ultimately reduced to the level of normal saline (i.e., about 0.9%) upon absorption by the body of the subject being treated.
