Prostatitis is one of the common diseases in adult males, especially chronic prostatitis due to recurrent attacks and chronic pain over time, patients’ quality of life decreases and manifestations such as sexual dysfunction, depression, insomnia, and memory loss. It causes tremendous pain to patients and is closely related to medical costs and resource depletion. Doctors are often asked by patients, “Can prostatitis be cured or not?” . The actual prostatitis can be cured or not to start with the prostatitis classification. The traditional prostatitis is divided into four categories: acute bacterial prostatitis, chronic bacterial prostatitis, chronic non-bacterial prostatitis, and prostate pain, and is classified by Meares-Stamey’s “urine four-cup method”. This classification reflects the past understanding of infection as the primary cause of prostatitis. After several years of research, it was realized that the main symptom of chronic non-bacterial prostatitis is pain, and the National Institutes of Health proposed a new NIH classification system based on the above-mentioned research. It is specifically divided into type I: acute bacterial prostatitis, type II: chronic bacterial prostatitis, type III: chronic prostatitis and chronic pelvic pain syndrome, and type IV: asymptomatic prostatitis. Type I has an acute onset, with obvious symptoms and good treatment, while Type IV is asymptomatic and generally requires no treatment. What we usually call prostatitis mainly refers to type II and type III. Type II and type III have similar clinical symptoms, mostly pelvic pain and abnormal urination. The type III lacks an objective and specific diagnostic basis, so attention should be paid to differentiating it from other diseases that cause pelvic pain and abnormal urination. Nowadays, these two types are mostly diagnosed by the “two cups of urine method”. The current medical opinion is that the treatment goal of type II and type III is to relieve pain, improve urinary symptoms and improve quality of life, and the evaluation of efficacy is based on symptom improvement. Drug treatment mainly includes antibiotics, alpha-blockers, and non-steroidal anti-inflammatory analgesics. Health education is also provided to patients, such as avoiding spicy food, smoking and alcohol, and avoiding sedentary lifestyle. In summary, when patients suspect prostatitis, they should be accurately diagnosed and classified first, then we can tell patients that type I can be eradicated and type IV is asymptomatic and generally does not require treatment. Type II and III cannot be cured, but they can control pain and other uncomfortable symptoms and improve the quality of life.
