According to the standards set by the National Institutes of Health in 1995, prostatitis is divided into four types, each with similar manifestations and individual characteristics, and what the general public calls chronic prostatitis corresponds to Type II and Type III of it. Type II: chronic bacterial prostatitis with recurrent lower urinary tract infection symptoms, similar to Type I, but lasting longer than 3 months. It may manifest as chills and high fever with persistent and pronounced symptoms of lower urinary tract infection, such as urinary frequency, urgency, painful urination, burning sensation in urination, difficulty in urination, urinary retention, and discomfort in the posterior urethra, anus, and perineal area. Elevated white blood cell count and positive bacterial culture in blood and urine. Type III: Chronic aseptic prostatitis, chronic pelvic pain syndrome, mainly manifested as pain in the pelvic region, seen in the perineum, penis, perianal region, urethra, pubic bone or lumbosacral region. Abnormal urination can be manifested as urinary urgency, frequency, painful urination and increased nocturia. Due to chronic pain that remains untreated, patients have a reduced quality of life and may have sexual dysfunction, anxiety, depression, insomnia, and memory loss. There is also type IV: asymptomatic prostatitis, which may also be treated as chronic prostatitis, which is manifested by the absence of subjective symptoms and only evidence of inflammation found during examinations concerning the prostate. So, chronic prostatitis is just a general term, not a professional medical concept and typing, it is difficult to distinguish the specific type by symptoms alone and requires the necessary auxiliary tests to confirm the diagnosis and guide the treatment.
