The severity of prostate enlargement does not depend on the size, but rather on the presence or absence of symptoms. If the examination shows prostate enlargement, but the patient has no symptoms, it means it is not serious. If there are obvious symptoms and the examination reveals prostate enlargement, suggesting that it is more serious, patients are advised to pay attention to it and undergo appropriate treatment. The normal volume of the prostate is generally 4 x 3 x 2cm, if the examination reveals an increase in volume, but the patient does not have abnormal urinary symptoms, indicating that it is not serious, attention can be paid to observation, without special treatment. If the prostate gland is enlarged and the volume is significantly larger than 4×3×2cm, and the patient’s urinary function is affected, the bladder capacity is reduced, and symptoms such as frequent urination, urinary urgency, urinary incontinence and increased nocturnal urination occur, suggesting that the condition is more serious, especially if there are symptoms such as difficulty in urination and dripping urine, suggesting that the condition is serious and suggesting timely treatment. Patients with prostate enlargement need to go to the hospital to cooperate with the doctor for examination, usually need to do rectal finger examination, also need to do urine routine, serum prostate-specific antigen determination, as well as ultrasound examination, urine flow rate measurement, urodynamic examination, can assess the severity of prostate enlargement. Patients can be treated with alpha blockers, or M receptor antagonists under medical supervision.
