Transient gross hematuria

Introduction Transient hematuria can be caused by pollen, chemicals or drug allergies. After strenuous exercise, transient hematuria can occur, even gross hematuria, and viral infections (such as colds) can occasionally occur, usually without significance. Only multiple examinations for true hematuria should be taken seriously and should be further examined.

Cause

The cause of transient gross hematuria:

Transient hematuria can be caused by pollen, chemicals or drug allergies.

After strenuous exercise, transient hematuria and even gross hematuria can occur. Viral infections (such as colds) can occasionally occur in hematuria, usually without significance. Only after multiple examinations for true hematuria should be taken seriously for further examination.

There are many reasons for causing hematuria:

1. Systemic diseases: blood diseases (leukemia), infectious diseases (such as epidemic hemorrhagic fever), cardiovascular diseases (such as congestive heart failure), connective tissue diseases (systemic lupus erythematosus), drugs (sulfa drugs, water) Salicylic drugs and anticoagulants).

2, urinary tract adjacent organ diseases: such as: acute appendicitis, acute or chronic pelvic inflammatory disease, colon or rectal diverticulitis, malignant tumors, and other diseases invading or stimulating the urinary tract, sometimes can produce hematuria, but not common.

3, kidney and urinary tract diseases: such as: various types of nephritis, renal basement membrane disease, pyelonephritis, polycystic kidney disease, renal ptosis, urinary tract stones, tuberculosis, tumors and vascular lesions, trauma and so on.

4, as well as certain poisons (phenol, carbon monoxide, chloroform, snake venom), drugs (sulfonamide, quinine), crush injury, burns, malaria, mistype blood transfusion and other causes of hemoglobinuria or myoglobinuria. Transient hematuria can be caused by pollen, chemical substances or drug allergies. After intense exercise, viral infection can also occur.

Examination and diagnosis of transient gross hematuria:

Transient hematuria: "After the exclusion of contaminated hematuria, injurious hematuria, etc., the number of red blood cells in the urine examination is 3, the field of view of high magnification or the number of red blood cells is 8000/ml, or the red blood cell count of 12 hours is more than 500,000. It can be diagnosed as true hematuria. It is generally believed that the appearance of true hematuria means that the kidney, ureter, bladder, prostate or urethra has lesions, or other organ diseases affect the urinary system, which should be highly valued."

Hematuria visible to the naked eye: First of all, urinary tract tumors, such as bladder tumors, kidney tumors, renal pelvis and ureteral tumors, urethral tumors, male prostate tumors, etc., especially elderly patients, the older patients with gross hematuria, who have urinary tract tumors The greater the possibility, the more serious the need for hematuria in the elderly. Bladder cancer hematuria has two distinct features, the first is painless, the patient can have obvious hematuria, but no pain; the second is intermittent hematuria, vascular rupture of the tumor site, ulceration, necrosis, causing vascular injury Hematuria, hemostasis after blood coagulation, and repeated bleeding after destruction. Patients with bladder cancer range from first gross hematuria to recurrent gross hematuria. Many patients are separated by half a year to one year. Treatment with antibiotics and hemostatic drugs can temporarily stop the hematuria, but it must not be taken lightly, otherwise it will delay diagnosis and treatment. The severity of gross hematuria is related to the size, number, and degree of malignancy of bladder tumors, but it is not necessarily proportional. The severity of bladder tumors cannot be estimated by the severity of gross hematuria. Gross hematuria, even if only once, should be examined in detail. Early bladder tumors have few symptoms of urinary tract irritation. If the bladder tumor is infected, or if the tumor grows in the lower part of the bladder, urinary urgency symptoms such as urgency, frequent urination, painful urination, and difficulty urinating may occur earlier.

Exercise hematuria refers to transient hematuria that occurs suddenly in healthy people after strenuous exercise. It is closely related to the excessive exercise intensity, the excessive increase in exercise volume, and the decline in physical function. It can not find other abnormal changes and causes through clinical examination, laboratory tests and special examinations. Most of the exercise hematuria is microscopic hematuria, a small number of gross hematuria, usually with other abnormal symptoms and signs after exercise, only fatigue fatigue. After the exercise is stopped, the hematuria disappears rapidly, generally no more than 3 days, and the prognosis is good, and has no effect on health. Exercise hematuria can be used as a signal that does not adapt to exercise load or decreased physical function.

It is very important to diagnose and treat exercise hematuria. Any case of hematuria after exercise should be carefully consulted and examined. Transient hematuria can only be diagnosed as exercise hematuria except for pathological hematuria caused by systemic diseases, urinary tract diseases, diseases of organs near the urinary system, and in line with the characteristics of exercise hematuria. It is forbidden to treat hematuria induced by exercise with pathological changes as exercise hematuria and delay treatment.

Differential diagnosis

Symptoms of transient gross hematuria confusing:

After exercise, hematuria was found to have hematuria after strenuous activities such as running or playing, but the body had no obvious discomfort and no other combined symptoms. This is hematuria after exercise, and the kidneys are damaged by strenuous exercise. After the exercise, "hemoglobinuria" sometimes appears. At this time, the urine color is soy sauce color, and there is no red blood cell or only a small amount of red blood cells when examined by urine microscopy. After exercise, hemoglobinuria is also called "exercise hemoglobinuria", which was named after the appearance of the soldiers. This disease contains free hemoglobin in the urine due to intravascular hemolysis during exercise. Most people have a good prognosis and can heal themselves. Generally, there is no adverse effect on health.

Hematuria with proteinuria: Renal hematuria refers to hematuria derived from glomeruli, clinical manifestations of simple hematuria, or hematuria with proteinuria. If the treatment is not thorough, repeated attacks or treatment failure, the condition can not be effectively controlled, and eventually lead to uremia.

Hematuria with poor urination, laborious and urinary drip, in elderly men are mostly prostatic hypertrophy, in middle-aged men should consider urethral stricture, urethral stones or bladder tumors.

Transient hematuria: "After the exclusion of contaminated hematuria, injurious hematuria, etc., the number of red blood cells in the urine examination is 3, the field of view of high magnification or the number of red blood cells is 8000/ml, or the red blood cell count of 12 hours is more than 500,000.
