Prostatitis does not discharge from the buttocks, but mainly from the urethra. Prostatitis is a series of symptoms such as pain in the pelvic area, abnormal urination and decreased sexual function caused by bacterial attack on the prostate or irritation by other factors. It is divided into acute bacterial, chronic bacterial, chronic and asymptomatic. The general clinical manifestations are urinary frequency, urinary urgency and urinary pain. Acute prostatitis will have urinary retention, chills and high fever. Chronic prostatitis will have urethral discharge, hypogonadism and so on. Because the prostate is connected to the urethra rather than the buttocks, it is usually in the urethra under the flow of secretion. If the patient found in the buttocks discharge, it is recommended to go to the hospital for examination, to clarify the cause of the disease under the guidance of the physician treatment.
