The Chinese Medical Association’s 2007 Guidelines for the Diagnosis and Treatment of Chronic Prostatitis suggests that some “aseptic” prostatitis, which is mainly chronic inflammation and recurrent or aggravated, may be related to infection with anaerobic bacteria or bacterial mutation to L-type. The recurrence and intractability of the disease is related to the inability to completely remove the microscopic plugs or pus plugs formed by the inflammation in the prostate duct system due to the curved and narrow structure of the prostate duct system; on the other hand, due to the existence of the blood-prostate lipid membrane barrier, conventional routes of drug administration such as intravenous infusion, intramuscular injection, and oral antimicrobial agents often fail to achieve effective therapeutic concentrations, resulting in the lingering of the disease. The two balloons close the upper and lower ends of the prostate section of the urethra, forming a relatively airtight cavity, and the specially designed injection tube lumen is pressurized and filled with the antimicrobial solution, so that the inflamed prostate gland tissue is directly immersed in the solution, thus achieving a very high drug concentration. The drug concentration is very high. This method can effectively solve the key problems of low local drug concentration in the prostate and poor drainage of the glandular ducts, which can significantly improve the clinical symptoms of patients and increase the clinical cure rate.
