Mechanism of microwave thermotherapy

Abstract

Possible mechanisms by which transurethral microwave thermotherapy creates an improvement in vodiing parameters are reviewed. The therapy creates coagulation necrosis in the hyperplastic adenoma, and thus has the potential to create volume reduction, change in the periurethral tissue, and changes in efferent neuromuscular elements and sensory neural elements. Evidence is presented that suggests that several of these mechanisms are likely important, and there is not a singular mechanism of action.
