What is the cause of male urine blood?

Urinating is something we do frequently in our daily lives. Generally, when our bodies are normal, our urine is transparent. If the urine is abnormal, we will find white or turbid substances in the urine. Especially for men with blood in the urine, it is more serious. In such cases, we need to conduct an examination. So, what is the reason for men's blood in the urine? Let's learn more about it through the following introduction.

1. Causes of hematuria

Hematuria is often caused by diseases of the urinary organs. Human urine is produced in the kidneys and discharged from the body through the renal pelvis, ureters, bladder, and urethra. Any disease or bleeding in these organs can cause hematuria. Common diseases that cause hematuria include various nephritis, urinary tract infection, hemorrhagic cystitis, urinary tract stones, renal tuberculosis, renal tumors, kidney and urethra injuries, etc. Hematuria is one of the main symptoms of the above diseases.

(II) Differential diagnosis of hematuria If hematuria is present at the beginning of urination but the latter part of the urine is normal, it is usually caused by urinary tract diseases. If hematuria is normal at the beginning of urination but appears at the end of urination, it is usually caused by cystitis and prostate disease. If hematuria is present throughout the whole process and the blood is dark red, it is usually caused by kidney diseases. Hematuria rarely presents as a sign of shock. Hematuria is commonly seen in the following diseases:

1 Acute glomerulonephritis with hematuria, oliguria, proteinuria, edema, hypertension, and tonsillitis one week before onset.

2 Pyelonephritis, hematuria with dysuria, urgency, frequency, low back pain, and fever.

3 The characteristics of urinary stones are hematuria accompanied by renal angina, or symptoms such as interrupted urination, dysuria, and urinary pain.

4 More than 90% of patients with renal tuberculosis have hematuria, characterized by urinary urgency, frequency, and gradually increasing pain during urination.

5 Kidney and urinary tract injuries are often accompanied by a history of lumbar or abdominal trauma, such as contusion, collision, and fall.

6 Allergic purpura is a disease with bleeding spots on the skin, gastrointestinal bleeding, and joint pain. Hematuria will appear 2 to 4 weeks after the bleeding spots on the skin.

7 Systemic diseases Vitamin C and vitamin K deficiency, blood diseases such as leukemia and hemophilia can cause hematuria.

8 Drug-induced hematuria Some drugs are harmful to the kidneys and can cause hematuria after taking them, such as gentamicin, tetracycline, sulfonamides, kanamycin, etc.

9 Transient hematuria is caused by drinking too little water. Drinking more water to dilute the urine is often caused by kidney stones, urinary tract tumors or urinary tract damage. In addition, inflammation can also cause hematuria. It is recommended to conduct urine tests, such as urine routine, three cups of urine, and urinary system B-ultrasound examination to confirm the diagnosis.

Through the above introduction, we know what causes men to urinate blood. When there is blood in the urine, it is an abnormal reaction of the body. We need to pay enough attention to it. The first thing to do is to go to the hospital for timely examination. After finding out the cause, timely treatment should be carried out. Do not delay the disease due to negligence.
