What causes blood in urine in men?

Blood in the urine in men may be caused by strenuous exercise, trauma, urethritis, prostatitis, renal tuberculosis, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Strenuous exercise: After intense physical activity such as long-distance running or playing basketball, men may experience rupture of capillaries in the kidneys due to excessive movement, leading to bleeding. This can result in blood streaks or clots in the urine. This is a normal phenomenon, and if there are no other discomfort symptoms, it usually gradually improves with rest.

2. Trauma: Injury to the male genital area from blows or impacts may cause rupture of surrounding capillaries, resulting in hematuria (blood in urine). Men are advised to seek prompt medical evaluation to ensure there are no more serious injuries. Symptoms typically resolve gradually once the injury heals.

3. Urethritis: This may be caused by prolonged sitting, unhygienic sexual practices, or similar factors. Inflammation can irritate the urethral mucosa, causing congestion and swelling, which leads to the aforementioned symptoms. It may also be accompanied by frequent urination and urgency. Men are advised to strictly follow medical instructions when using medications such as azithromycin granules, cefixime granules, or roxithromycin tablets for treatment.

4. Prostatitis: This may be associated with poor dietary habits, excessive fatigue, and other factors. Prostatitis can lead to fibrosis of prostate tissue, causing local blood vessel dilation and potentially resulting in blood in the urine. It is often accompanied by urinary pain and perineal pain. Men should take medications such as minocycline hydrochloride capsules, celecoxib capsules, and Qianlieshutong capsules orally as directed by a physician to improve symptoms.

5. Renal tuberculosis: This may result from malnutrition, poor personal hygiene, and similar factors. Renal tuberculosis often causes kidney function damage and may lead to rupture of renal blood vessels, allowing small amounts of blood to leak into the urine, manifesting as hematuria. It may also be accompanied by symptoms such as frequent urination and lower back pain. Men are advised to strictly follow medical instructions when using medications such as rifampicin tablets, isoniazid tablets, and ibuprofen sustained-release capsules for treatment.

In daily life, men are advised to maintain good personal hygiene, change undergarments frequently, and live in quiet, well-ventilated environments, all of which are beneficial to health.
