Human urine has a red appearance, and the most common cause is hematuria. There are many diseases that cause hematuria, such as urinary system infection, urinary calculi, tumors, malformations or coagulation dysfunction and trauma, which will all lead to the phenomenon of urine redness.
In this case, the increase of red blood cells is caused by internal reasons, and the reasons for the increase of red blood cells in urine routine should be clarified while checking urine routine. If it is an infectious disease, it can be treated with anti-inflammatory and symptomatic treatment. If it is a stone or tumor, it is necessary to have surgery.
In addition, some anti-tuberculosis drugs can also cause urine redness because people ingest foods with dark red color, such as red pitaya or take some drugs in the near future.
In this case, there will be no obvious increase of red blood cells in urine routine examination, mainly due to the increase of red pigment in urine. The cause of red lesions should be clarified according to the situation, and effective prevention can alleviate the red urine.
Urine is a possible cause of redness:
First, eating foods, fruits or drugs such as rifampicin capsules related to red pigments can lead to red urine staining. At this time, the urine routine examination does not contain red blood cells, nor is it accompanied by any symptoms of urinary tract irritation. After stopping the intake of related drugs, food, fruits, etc., the urine color can return to normal.
Secondly, urinary calculi can cause local mucosal ulceration and bleeding, resulting in red urine staining, which is often accompanied by pain in the part where the calculi are located, such as low back pain and abdominal pain. It is suggested to carry out B-ultrasound examination of the urinary system for further diagnosis.
Third, urinary tract tumors, such as bladder tumors or renal tumors, can all appear urine red staining, which is more common in older patients. CT examination of urinary system is needed to further rule out the presence or absence of tumors.
Fourth, acute urinary tract infection can cause congestion, edema and bleeding of urinary tract mucosa, and red staining of urine, often accompanied by urinary tract irritation symptoms such as frequent urination, urgency and micturition pain. Routine urine examination shows that the number of white blood cells increases, the number of bacteria increases with the number of red blood cells, and further urine culture examination can be carried out to confirm the diagnosis.
