What is the reason for blood in urine?

Women sometimes find blood after urinating, which is mostly caused by urinary tract and kidney problems. Of course, if a woman is found to have blood in her urine, she should first determine whether it is caused by menstruation or hemorrhoidal bleeding. If it is not one of these two, it can be basically determined that it is caused by the urinary tract. The urinary system is very easy to be infected. Common symptoms are frequent urination, urgency, and pain when urinating. If hematuria is accompanied by severe pain, you should consider the problem of tumors and stones.

First: If hematuria occurs at the beginning of urination but the later urine is normal, it is usually caused by urethral diseases. For example, if the beginning of urination is normal but hematuria occurs when urination is about to end, it is usually caused by cystitis and prostate disease. If hematuria occurs throughout the whole process and the blood is dark red, it is usually caused by kidney diseases.

Second: There is a high possibility of urinary tract infection. Common urination abnormalities caused by urinary tract infection are frequent urination, urgency, and pain when urinating. Urinary incontinence and urinary retention may also be seen. In the early stage of chronic renal failure caused by chronic pyelonephritis, there may be polyuria, and in the later stage, there may be oliguria or anuria. You can actively go to the hospital for a routine urine test, blood test and urine bacterial culture. Generally, you can drink more water and actively receive anti-infection treatment.

Third: Symptomatic hematuria should first consider the possibility of urinary tract tumors. If hematuria is accompanied by pain, especially colic, urinary tract stones should be considered. If it is accompanied by urinary pain and interrupted urinary flow, bladder stones should be considered. If it is accompanied by obvious bladder irritation symptoms, urinary tract infection, urinary tract tuberculosis and bladder tumors are more common.

Fourth: When hematuria is found, we should first determine whether it is true hematuria, that is, to rule out false hematuria and red urine caused by certain reasons. The former is caused by menstruation, hemorrhoidal bleeding or diseases near the urethra, which produces bleeding mixed in the urine; the latter is caused by contact with certain pigments or oral administration of rifampicin and other drugs, as well as certain poisons (phenol, carbon monoxide, chloroform, snake venom), drugs (sulfonamide, quinine), crush injuries, burns, malaria, wrong blood transfusions, etc., which cause hemoglobinuria or myoglobinuria. Transient hematuria can be caused by allergies to pollen, chemicals or drugs, and can also occur during menstruation, after strenuous exercise, and during viral infection. It is generally of no great significance and should only be taken seriously when the above situations are excluded and multiple tests show hematuria. The diagnosis is made through medical history, physical examination, laboratory tests and other auxiliary examinations.

Precautions
