What causes men to urinate frequently, painfully, and with blood in their urine?

When your body clearly feels unwell, but you are too embarrassed to say it. For example, frequent urination, urgency, blood in urine, pain when urinating, etc., what are the causes of these symptoms?

Several major causes of frequent urination, painful urination, and blood in urine:

1. Inflammation of the reproductive system, especially acute cystitis and tuberculous cystitis. Other diseases such as prostatitis, urethritis, pyelonephritis, chronic penile capitis and vulvitis in children can also cause frequent urination.

2. Bladder stones can also lead to frequent urination and reduced bladder capacity, such as bladder space-occupying lesions, pressure from the enlarged uterus during pregnancy, tuberculous bladder contractions, or larger bladder stones.

3. If there is obvious pain at the beginning of urination or dysuria, the lesions are mostly in the urethra, which is common in acute urethritis.

4. If there is obvious pain at the end of urination, or if there is still pain after urination, or if there is a feeling of "empty pain", or if there is pain even without urination, the disease is mostly in the urethra or adjacent organs, such as trigone inflammation, prostatitis, etc.

5. Stinging or burning pain during urination is often seen in acute inflammatory stimulation, such as acute urethritis, cystitis, prostatitis, and pyelonephritis.

6. There are also some psychogenic urinary frequency, which only occurs during the day or before going to sleep at night, often due to mental tension or hysteria. At this time, it may also be accompanied by urinary urgency and pain.
