There is provided a method of treating a patient comprising: screening a patient suffering from signs and/or symptoms of at least one medical condition secondary to increased sympathetic tone; selecting the patient for treatment by ablation of at least one neural structure containing sympathetic nerves to reduce the sympathetic tone, the neural structure comprises one or more of: celiac ganglion, superior mesenteric ganglion, inferior mesenteric ganglion, aorticorenal ganglion; selecting a target of at least one measureable parameter affected by the sympathetic tone; ablating at least a portion of the neural structure to deactivate the portion of the neural structure; monitoring changes in the at least one measureable parameter; comparing the at least one measureable parameter to the selected target; and performing another ablation of the same neural structure, and/or another neural structure, based on the comparison.
