Prostate diseases are common diseases of adult men, and generally refer to prostatitis, prostatic hyperplasia, prostate cancer and the like. Prostatitis is an inflammation of the prostate. Roughly classified into acute and chronic, but the causative agent is caused by bacterial and non-bacterial infections. The main symptoms are pain in urination, whitish urine, burning urine, frequent micturition, distending pain and discomfort of lower abdomen and perineum; when severe, it may cause heat generation. Benign prostatic hyperplasia is the most common benign disease among causes of micturition disorders in middle-aged and elderly men. It is mainly manifested by the hyperplasia of interstitial and glandular components of prostate gland in histology, enlargement of prostate gland in anatomy, clinical symptoms such as lower urinary tract symptoms and urinary bladder outlet obstruction. Prostate cancer is often asymptomatic in the early stage, and when cancer cells grow, prostate bodies become large and press the urethra to cause dysuria. These cancer cells can spread with the blood to other parts of the body. Generally, the course of the disease is slow and the late stage of the disease can cause symptoms such as bladder neck obstruction and distant metastasis.
