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.

Cause

Movement of hematuria caused by rupture of glomerular cells due to excessive shock, red blood cells through the glomerular cyst, and the renal tubules are no longer absorbed. During exercise, the blood vessels of the whole body muscles and joints dilate and blood flow increases dramatically. In order to meet this need, the blood flow of the glomerulus is reduced, and the oxygen may be temporarily insufficiently supplied, so that the cell function on the capillary wall cannot be fully exerted, the cell arrangement changes, and the cell gap increases. It is possible that hematuria may occur when red blood cells that flow only in the blood vessels are filtered into the cystic cavity through the enlarged cell gap.

Differential diagnosis

Differential diagnosis of hematuria after exercise :

1, abdominal pain with hematuria: abdominal pain with hematuria is one of the clinical manifestations of kidney and ureteral stones.

4, 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.

5, intermittent hematuria: hematuria refers to red blood cells 3 / HP in the urine, centrifuged urinary red blood cells > 5 / HP, or 12 hours urine Addis count > 500,000, is a common urinary system symptoms in children. The causes are urinary tract inflammation, tuberculosis, stones or tumors, trauma, drugs, etc., which have a great impact on the body. In recent years, there is no obvious accompanying symptom of hematuria, and most of them are glomerular hematuria, which has been widely regarded and studied. Intermittent hematuria is a symptom that occurs when hematuria occurs.
