A trick to determine prostatitis is not true. For the diagnosis of prostatitis, the diagnosis should be confirmed by combining medical history, clinical manifestations, rectal fingerprinting and laboratory tests. 1. Medical history: the patient has recurrent counter-urinary tract infections. 2. Clinical symptoms: vague pain in the perineum and lower abdomen; symptoms of urinary frequency, urgency, pain and burning. 3. Rectal fingerprinting: operated by a professional doctor, touching the prostate to check whether there is enlargement, pressure and pain and other abnormal conditions. 4. Laboratory tests: urine and prostate fluid are examined to determine whether pathogenic bacteria are present. Only a combination of tests can confirm the diagnosis of the disease. In the examination, it should also be identified with prostate hyperplasia, prostate cancer and other diseases. Prostatitis patients need to consult a doctor in time for examination and early treatment.
