    摘要： Sterile injectable formulations, which comprise the following: (a) a ablation agent in an amount effective to cause necrosis of tissue, and (b) a biodisintegrable viscosity adjusting agent in an amount effective to render the formulation highly viscous, (c) an optional imaging contrast agent, (d) an optional therapeutic agent, and (e) an optional liquid selected from water and an organic solvent. Also described are novel prostatic ablation formulations, which comprise a prostatic ablation agent selected from free-radical generating ablation agents, oxidizing ablation agents and tissue fixing ablation agents. Further aspects of the invention relate to methods of treating a variety of diseases and conditions, including benign prostatic hypertrophy, in which above injectable formulations are injected into the tissue of a subject, optionally with the assistance of a non-invasive imaging technique.
