1. Why does prostate hyperplasia cause frequent urination?
Answer: Frequent urination, as a common symptom of benign prostatic hyperplasia, is mainly due to the aggravation of obstruction in the bladder neck caused by benign prostatic hyperplasia. Therefore, the bladder cannot be completely emptied every time urination, and there is often residual urine in the bladder. Due to an increase in residual urine volume and a decrease in effective bladder capacity, the interval between urination times is naturally shortened, resulting in frequent urination.
2. Is excessive nocturia an early manifestation of benign prostatic hyperplasia?
Answer: An increase in the frequency of nocturia is the first symptom of prostate hyperplasia, and the number of nocturia is often proportional to the degree of prostate hyperplasia. Patients who previously did not have nocturia often experience early prostate hyperplasia when they experience 1-2 episodes of nocturia; The progression from 2-3 urinations per night to 5-6 urinations indicates that the obstruction of the bladder neck is becoming increasingly severe, which is caused by congestion and stimulation of the prostate at night.
3. Why does prostate hyperplasia cause hematuria?
Answer: After prostate hyperplasia in elderly men, the mucosal capillaries covering the prostate become congested and small blood vessels become varicose. The prostate, urethra, and submucosal blood vessels of the bladder neck are pulled by enlarged glands, which can easily cause blood vessel rupture when the bladder contracts. The amount of bleeding in patients varies, some can be seen with the naked eye, while others need to be detected by doctors using a microscope. This type of hematuria often occurs intermittently, mostly after urination.
