Prostate cavity intervention therapy is a new type of treatment for chronic prostatitis that has emerged in recent years. The principle of treatment is: with the assistance of microwave thermotherapy, high pressure localization and other conditions, drugs are injected into the diseased part of the prostate urethra, mainly including some antibacterial drugs. In this way, the concentration of local drugs can be effectively increased to enhance the effectiveness of drugs; in addition, it can also act directly on the prostate cells to improve their metabolism and repair capacity, which can really achieve the purpose of treatment. The study pointed out that the cavity interventional therapy can not only significantly improve the treatment efficiency of chronic prostatitis patients, reduce the pain of patients, but also improve the patient’s satisfaction with the treatment, enhance the patient’s trust in the hospital, and reduce the occurrence of medical disputes. It is recommended that patients go to regular hospitals and follow the doctor’s instructions for prostate cavity interventional therapy, in order to achieve the best therapeutic effect.
