There is a dearth of literature on heat therapy and prostatitis. The therapies used different energy sources, including interstitial heat and microwaves, and were delivered both transrectally and transurethrally. Most data precede our present system of nomenclature and therefore are difficult to compare, even with the literature of their day. Validated instruments were rarely used to determine efficacy, and most outcome measures were subjective. We will need well-designed prospective clinical trials using objective outcome measures and validated symptom indexes. Until then the use of heat therapy for prostatitis should be considered experimental.
