Chronic prostatitis (CP) is a common chronic urinogenital inflammatory disease which is apt to occur on male patients aged about 20 to 40 years old whose onset rate in China is about 8.4% of Chinese population. Its pathogenesis in modern medicine is still unclear, leading to not satisfactory clinical effect. Traditional Chinese medicine has certain advantages and potential in the treatment of CP. Especially the external therapies of traditional Chinese medicine have the advantages of avoiding the first-pass effect of orally-administration medicine caused by the liver and adverse reactions, being absorbed quickly, instant therapeutic effect, giving full play to the drug action. Therefore, TCM external therapies are getting more and more attention, and becoming a research hotspot. At present, many scholars have done a lot of research in clinical trials, accumulating a large number of effective experience.
