Prostate enlargement, commonly known as prostate enlargement, is a common disease among middle-aged and older men. Because the prostate gland wraps around the urethra in men, it often causes difficulty in urination when the prostate gland is enlarged. The specific manifestations are: 1. more frequent urination, especially at night; 2. not far to urinate, easily wetting clothes and pants; 3. waiting to urinate (waiting for a while to urinate after taking off pants); 4. incomplete urination, often with dripping; 5. even some patients may appear hematuria. The above symptoms are aggravated by cold, overexertion, sedentary, holding urine, too frequent sex, etc., and may even develop diseases such as urinary retention and impaired kidney function.
