What causes blood in the urine? What causes hematuria?

Haematuria. 1) Stones or tumors commonly found in the urinary tract (kidneys, ureters, bladder, prostate, urethra).

If there are white blood cells in the urine, it is a urinary tract infection.

2) Exercise nephritis: hematuria secondary to strenuous exercise.

3) Allergic hematuria.

4) The drug can cause reddish-discolored urine (no hematuria). Includes: sulfonamides, quinine, rifampicin, phenytoin.

5) Hemoglobinuria can be seen in: urine sickle anemia, renal arteriovenous malformation.

6) Nephrotic syndrome: glomerulonephritis developed by streptococcal infection, glomerular fibrinous necrosis of malignant hypertension.

7) Inferior vena cava obstruction secondary to bladder varices. and Alport syndrome (hereditary nephritis).

There are many causes of hematuria, which generally include the following;

1. Urological diseases.

Such as all kinds of nephritis (acute glomerulonephritis, viral nephritis, hereditary nephritis, purpuric nephritis), stones (kidney, bladder, urethra), heart and kidney tuberculosis, various congenital malformations, trauma, tumors, etc.

2. Systemic diseases.

Such as bleeding disorders, leukemia, heart failure, sepsis, vitamin C and K deficiency, hypercalciuria, neonatal symptoms, etc.

3. Physical and chemical factors.

Such as food allergies, radiation exposure, drugs, poisons, post-exercise, etc.

In order to be clear, it is very important to determine the location of hematuria, and the urine three-cup test can understand the hematuria, and the method is very simple.

Three-cup urine test: take 3 cups, in one urine, the first cup takes the anterior urine, and the second cup takes the middle one.

Urine, the third cup to take the posterior segment of urine. If the first cup is hematuria, it means that the blood is coming from the urethra; The third cup of hematuria is terminal hematuria, and the lesions are mostly in the bladder or posterior urethra; The first, second, and third cups are all blood-colored, i.e., hematuria throughout, suggesting that the lesion is in the kidneys or in the urinary tract above the bladder.

There are many causes of hematuria. Generally includes:

1.Urinary stones: These include kidney, ureter, bladder or urethral stones.

2.Genitourinary infections: such as pyelonephritis, renal tuberculosis, cystourethritis, prostatitis, etc.

3.Primary nephritis: these include acute and chronic nephritis, focal nephritis, benign acute hemorrhagic nephritis, etc.

4.Secondary nephritis: purpuric nephritis, lupus nephritis, IgA nephropathy.

5.Genitourinary tumors: renal tumors, ureteral tumors, bladder tumors, prostate tumors, etc.

6.Other urological diseases: such as renal prolapse, migratory kidney, congenital polycystic kidney disease, etc.

7.Urinary tract injury: damage to the kidneys by various chemicals or drugs, hematuria caused by sulfonamides, etc.

If you want to confirm the location of bleeding, you can take 3 cups, in one urine, the first cup of urine is taken from the anterior segment, the second cup is taken from the middle segment, and the third cup is taken from the posterior segment of the urine. If the first cup is hematuria, it means that the blood is coming from the urethra; The third cup of hematuria is terminal hematuria, and the lesions are mostly in the bladder or posterior urethra; The first, second, and third cups are all blood-colored, i.e., hematuria throughout, suggesting that the lesion is in the kidneys or in the urinary tract above the bladder. It is necessary to determine which disease is causing the hematuria, or whether it is based on symptoms and physical signs, various experiences, x-rays, CT tests, and even biopsies of the kidneys to confirm the diagnosis.

There are many causes of hematuria, such as urinary tract infection, stones, tuberculosis, tumors, malformations, thrombocytopenic purpura, etc., color ultrasound examination can be performed, if necessary, urography, ureteroscopy and other examinations can be performed, according to the results of the examination and combined with the clinical manifestations of analysis and judgment, clear ** targeted**, patients with severe hematuria can consider bed rest, reduce activities, and drink more water.

Add a little upstairs, and the rest is all kinds of primary and secondary glomerulonephritis.

Hematuria is a common symptom in urology, which is mainly divided into microscopic hematuria and gross hematuria, microscopic hematuria refers to the elevated red blood cells in the urine found under the microscope, and gross hematuria refers to the blood in the urine seen by the eyes. Most of the patients found that the hematuria is gross hematuria, and there are many causes of gross hematuria, and the common causes are as follows.

The most common cause of hematuria is urinary tract infection, such as cystitis, which is often accompanied by frequent urination, urgency, painful urination, pain in the lower abdomen, and in severe cases, blood clots and fever, which are less common in men than in women. In addition, urinary stones are also prone to hematuria, which is mostly caused by pain in the lower back and abdomen and then hematuria, mainly due to bleeding caused by stones damaging the renal pelvis and ureteral mucosa. Urinary system tumors are also a major cause of hematuria, and most of the hematuria caused by tumors is the most advanced hematuria, and most of them will appear in the middle and late stages of tumors, such as kidney cancer, bladder cancer, prostate cancer, etc.

Secondly, urinary system damage can also cause hematuria, such as urethral rupture, bladder rupture, etc.

In summary, there are many causes of gross hematuria, and the specific causes need to be determined in combination with the patient's medical history, accompanying symptoms, physical examination, and corresponding ancillary tests.

Bladder deficiency causes this.

Hematuria may be caused by urinary tract infections, urinary tract stones, urinary tumors, etc. Hematuria can also be seen due to other causes, such as coagulopathy. It is recommended to seek medical attention in time and follow the doctor's instructions for the next examination, clarify the cause under the guidance of the doctor, and actively cooperate with the doctor to deal with it or**.

Hematuria is blood in the urine that is brownish-red. Homogeneous hematuria is mostly renal hemorrhage; Long blood clots in the urine, usually formed in the ureters; If hematuria is terminally present, it is usually bladder bleeding; At first, hematuria is usually urethral bleeding.

1.Patients with hematuria accompanied by eyelid and general edema, hypertension, and a history of infection are mostly acute nephritis.

2.Patients with panhematuria and a history of dysuria and trauma are traumatic.

3.Hematuria accompanied by urinary frequency, urgency, and painful urination, and a history of previous tuberculosis is urinary tuberculosis.

4.Hematuria with colic, and a history of urinary stones in the past are urinary stones.

5.Hematuria accompanied by anemia, purpura, and hepatosplenomegaly is mostly a blood disease.

6.Hematuria is present and there is a history of taking sulfonamides, which is drug-induced hematuria.

Hematuria is often caused by diseases of the urinary organs. Human urine is produced in the early days of the kidneys, and is excreted through the renal pelvis, urethral tube, bladder, and urethra.

Prostatitis or vesiculitis, stones.
