Prostatitis can affect adult men of all ages, with a higher prevalence in adult men under the age of 50. The onset of prostatitis may also be related to season, diet, sexual activity, inflammation of the genitourinary tract, benign prostatic hyperplasia or lower urinary tract syndrome, occupation, socioeconomic status, and psychosomatic factors. According to the criteria established by the National Institutes of Health in 1995, prostatitis is divided into four types: Type I: Acute bacterial prostatitis with an acute onset, which may manifest as chills, high fever, accompanied by persistent and obvious symptoms of lower urinary tract infection, such as urinary frequency, urgency, painful urination, burning sensation in urination, difficulty urinating, 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 II: Chronic bacterial prostatitis with recurrent lower urinary tract infection symptoms, similar to type I, but lasting longer than 3 months. Type III: Chronic aseptic prostatitis with pain in the pelvic region, which can be seen in the perineum, penis, perianal area, urethra, pubic bone or lumbosacral area. Urination abnormalities can be manifested as urinary urgency, frequency, painful urination and increased nocturia. As chronic pain remains untreated, patients have reduced quality of life and may have sexual dysfunction, anxiety, depression, insomnia, and memory loss. Type IV: Asymptomatic prostatitis, no subjective symptoms, only evidence of inflammation is found during examinations concerning the prostate. So, different types of prostatitis, symptoms have both similarities and their own characteristics, it is difficult to distinguish the specific type by symptoms alone, the necessary auxiliary tests are needed to confirm the diagnosis and guide the treatment.
