Urine is red

People excrete urine every day. Urine is mostly colorless or yellow, which is closely related to the substances it contains. But if you find that your urine is red, you should be careful. From a health perspective, urine can speak. Although there is no pain sometimes, it is best to go to the urology department for a detailed examination to find the cause as soon as possible. The following is a detailed explanation of the issue of red urine.

Red urine needs attention

Hematuria is an important sign of urinary tract abnormalities. The color of the discharge varies from pink, bright red, to dark red or brown, depending on the location, time and amount of bleeding. However, certain foods such as pitaya, certain drugs such as phenazopyridine urethral analgesics, sulfonamide antibiotics, tuberculosis drug rifampicin, and vitamin B can also cause "hematuria-like" color.

Hematuria is a warning sign that something is wrong with your body

However, some hematuria is "microscopic" hematuria, where the change in urine color cannot be detected by the naked eye. Red blood cells can be found in urine during urinalysis. Judging from the shape of the red blood cells, hematuria with deformed red blood cells is caused by damage to the kidney filtration system, which causes the red blood cells to be squeezed and deformed during filtration; hematuria with uniform red blood cells is caused by lesions in the urine collection and excretion system below the renal parenchyma, including the renal pelvis, ureter, bladder, male prostate, urethra, etc.

In addition to hematuria, urine occult blood reactions also include hemoglobinuria and myoglobinuria. Hemoglobinuria is the presence of a large amount of hemoglobin in the urine, which may be caused by hemolytic anemia, transfusion reaction, severe burns, infection, and intense exercise; while myoglobinuria is protein dissolved in muscle tissue, which is caused by the destruction of muscle tissue due to trauma, prolonged coma, cramps, muscle metabolic diseases, etc.

Painless hematuria is more likely to be ignored

Hematuria is not a disease but a "warning sign", especially painless hematuria, which should not be taken lightly. Doctors will have different treatment methods and options depending on the cause of hematuria. Don't ignore the following 7 major warning signs of red urine.

1. Inflammation: Urethritis, cystitis, pyelonephritis, male prostate inflammation, etc. are often accompanied by other symptoms, such as painful urination, lower abdominal pain, back pain, fever, etc., which are generally treated with antibiotics.

2. Stones: Kidney stones, ureteral stones, bladder stones, urethral stones, etc. are generally treated conservatively, with drug excretion therapy, or endoscopic surgery, percutaneous nephrostomy, laparoscopic or open surgery to remove stones, and extracorporeal shock wave lithotripsy, etc., depending on the patient's condition.

3. Abnormalities of the coagulation system: such as platelet deficiency, hemophilia, etc., are also one of the important causes of hematuria because Chinese people often use anticoagulants. In addition to treating the causes, the dosage of anticoagulants can be adjusted with the permission of the attending physician.

4. Tumors: Renal cell carcinoma, renal pelvic epithelial carcinoma, ureteral epithelial carcinoma, bladder epithelial carcinoma, urethral epithelial carcinoma or prostate cancer, etc., need to be treated with surgery, chemotherapy, radiotherapy, etc. according to the stage of the disease.

5. Trauma: such as car accidents, external impacts or puncture wounds, etc., conservative observation treatment, vascular embolization or surgical hemostasis must be adopted according to the type and location of the injury. Sometimes due to combined injuries to other organs, it is necessary to discuss and decide on the treatment method with relevant doctors.

6. Exercise: A small number of people may also have hematuria after strenuous exercise. Generally, the condition will improve after changing the intensity and method of exercise.

7. Menstruation : Sometimes when you have a urine test during your menstruation, menstrual blood may be mixed in with the urine.

Usually, "microscopic hematuria" and "asymptomatic hematuria" are easily ignored because there are no obvious discomfort symptoms, thus delaying medical treatment, which will reduce the early detection rate of the disease and affect the cure rate of the disease, so special attention must be paid.
