Blood in the urine without pain, i.e. painless hematuria, may be bladder cancer, or other diseases, such as urinary tract infection, prostate hyperplasia, bladder tuberculosis and other diseases.
1. Bladder cancer: painless hematuria is a common clinical manifestation of bladder cancer, hematuria is not necessarily proportional to the size and severity of the tumor, and hematuria can be intermittent, resulting in the illusion of “getting better” or “self-healing”.
2. Urinary system infection: genitourinary system infection will destroy the epithelial cells of the urinary system, resulting in capillary congestion, bleeding, and causing painless blood in urine. Laboratory tests often suggest that there are elevated white blood cells and red blood cells in the urine.
3. Prostatic hyperplasia: Prostatic hyperplasia is a common and frequent disease in older men. When the prostate gland continues to enlarge, the surface blood vessels are constantly stretched, resulting in painless blood in the urine, urination effort, and a significant increase in the frequency of nocturia.
4. Bladder tuberculosis: It is a kind of urinary tuberculosis, which is caused by the invasion of tubercle bacillus into the bladder. Usually with frequent urination, urinary urgency as the main symptoms, when the tuberculosis bacillus infection is aggravated, the bladder tissue or bladder mucosa rupture bleeding, there will be blood in the urine painless symptoms.
There are many other causes of painless hematuria, if painless hematuria occurs, it is recommended to go to the hospital in time.
