In accordance with the 1995 National Institutes of Health classification, prostatitis is divided into four types, of which type II and type III belong to the traditional term chronic prostatitis, these two types not only do not heal themselves, but also have a long course prone to recurrence and difficult to cure. If the efficacy is unsatisfactory, other sensitive antibiotics can be used instead. Alpha-blockers can be used to improve urinary symptoms and pain. Botanical agents, NSAIDs and M-blockers can also improve the associated symptoms. Infection is often difficult to control if not properly treated. Type IIIA: The etiology is related to other factors besides pathogenic bacterial infection. Oral antibiotics can be given for 2 to 4 weeks, and then the decision to continue antibiotic therapy is based on its efficacy feedback. Alpha-blockers are recommended to improve urinary symptoms and pain, and phytochemicals, NSAIDs and M-blockers are also available to improve urinary symptoms and pain. This type has a longer duration and is more difficult to treat than type II. Type IIIB: medications such as alpha-blockers, botanicals, NSAIDs and M-blockers are recommended for treatment. So, chronic prostatitis still needs regular treatment to be controlled, although the course of the disease is longer and the symptoms may be relieved at some point, above for the treatment of chronic prostatitis.
