Is blood in the urine a cancer, and blood in the stool or blood in the urine means cancer?

Common diseases in urology can also easily cause hematuria, such as acute urinary tract infection, in which there is inflammation of the mucosa of the urinary tract, resulting in bleeding and hematuria. It is recommended to go to a regular hospital for examination and diagnosis in time to avoid delaying the condition.

Duomu Health will answer for you: common causes of occult blood are: 1. Kidney disease, glomerulonephritis, nephrotic syndrome, systemic lupus erythematosus, etc. 2. Inflammation.

Glomerulonephritis, pyelonephritis, and cystitis can all cause potential bleeding in the urine. 3. Stones. Stones such as the kidneys, ureters, and bladder can cause occult blood in the urine.

4. Tumors. Malignant or benign tumors of the kidneys, bladder, and ureters can cause occult blood in the urine. 5. The most important clinical manifestation of hereditary nephritis is urine occult blood.

In addition, women occasionally have occult blood in the urine, and it can also be caused by strenuous exercise and medication. It is recommended to check the kidney function first, which requires fasting blood drawing, and then a urological ultrasound.

Duomu Health, Duomu maintains good cooperative relations with many of Japan's top professional hospitals, and is a relatively reliable institution.

Blood in the stool and blood in the urine are completely different from cancer. The appearance of one should not be suspicious and the other should be arranged.

1. Blood in the stool and urine is generally a symptom of bleeding due to damage to the stomach and kidneys.

2. Cancer is a disease, and it can be said that it is not an injury. Cancer is a virus, a disease that hurts. It is not a "injury" of bleeding, and cancer generally bleeds pus and blood, not blood, so it is generally not seen that there is blood in stool or urine.

3. Therefore, to a certain extent, there is no greater direct relationship between blood in the stool and blood in the urine.

Clinical data have reported that kidney cancer accounts for 40% of patients with ** hematuria, bladder cancer accounts for almost 50%, and a small number of patients have renal vascular disease and filariasis. Most of these cancers occur in middle-aged and elderly people over the age of 40. Therefore, when people have ** hematuria in middle age, they must remain vigilant.

From the first occurrence of hematuria, the cause should be identified and countermeasures should be taken as soon as possible. Here's an introduction to the dangers of hematuria:

Occasional blood in the urine is not painful or itchy, and there is no abnormality in the body, which does not mean that it is healthy. **. Intermittent blood in the urine is an early sign of the disease, and it is the easiest to be ignored"Disease"It's gone. In fact, this kind of intermittent, ** hematuria is often a clinical manifestation of urinary tumors, and if the hematuria is aggravated suddenly, it is often an advanced stage of the tumor.

1. Experts propose that as long as there is hematuria, no matter how much or too little, even if it is not painful, it is only once for a long time, it is necessary to arouse a high degree of vigilance, and go to the specialist of a large hospital for examination as soon as possible, because according to clinical observation, 10%-20% of patients with blood in urine are related to malignant tumors.

2. Within two years after surgery, about 1 2 patients will have bladder cancer**. Therefore, bladder cancer patients should be closely followed up in the first 2 years after surgery, and cooperate with postoperative chemotherapy to prevent and reduce the chances of **.

3. Blood in urine is not a disease, but it is a precursor to many diseases, the most common are blood in urine caused by stones and urinary tract infections and blood in urine caused by bladder cancer and kidney cancer. Blood in the urine caused by stones and urinary tract infections is usually taken seriously by patients because of their pain and frequency, and they are sought care in a timely manner. However, blood in the urine caused by bladder cancer is not painful, and the frequency of blood in the urine is very low in the early stage, only once in a few months, which is often overlooked, which is the case of the above-mentioned patient, if diagnosed in time as early as a year ago, and in our hospital**, the ** rate can reach 90%.

Prostate cancer, bladder cancer, and hepatobiliary cancer can also be caused. Kidney cancer.

Hematuria is an abnormally increased excretion of red blood cells in the urine, which is a sign that there may be a serious condition in the urinary system. Centrifugal precipitation of urine with 3 red blood cells per high magnification field, or more than 1 or 100,000 urine red blood cell count in 1 hour or urine sediment count more than 500,000 in 12 hours, all indicate an abnormal increase in red blood cells in the urine, which is called hematuria. In mild cases, erythrocytosis is only found under the microscope, which is called microscopic hematuria; In severe cases, the appearance is washed or contains blood clots, which is called gross hematuria.

Usually 1ml of blood per litre of urine is visible to the naked eye, and the urine is red or like a wash of flesh.

Causes of hematuria].

More than 95% of hematuria is caused by diseases of the urinary system itself, among which glomerular diseases (acute nephritis, rapidly progressive nephritis, membranoproliferative nephritis, mesangial proliferative nephritis, focal glomerulosclerosis, etc.), kidney cysts, stones (kidney, ureter, bladder, urethral stones), prostatic hyperplasia, urinary tract infectious diseases (tuberculosis, pyelonephritis, cystourethritis, prostatitis) and tumors (kidney, ureter, bladder, prostate tumors) are the most common. Other diseases such as coagulation abnormalities (idiopathic or drug-induced thrombocytopenia, hemophilia, scurvy, etc.) and systemic diseases (aplastic disease, leukemia, systemic lupus erythematosus, dermatomyositis, leptospirosis, epidemic hemorrhagic fever, etc.) can also cause hematuria.

Blood in the urine is called hematuria, also known as blood in the urine.

Normally, there are no red blood cells in the urine. In medicine, the patient's urine is centrifuged and precipitated, and then examined with a microscope, if there are more than 5 red blood cells in each high-power field of view, it is called hematuria. If only red blood cells are detected under the microscope, but the eyes cannot see the blood in the urine, it is called microscopic hematuria; If the eye can see that the urine is "washed water" or bloody, or even that there are blood streaks or blood clots in the urine, it is called gross hematuria.

Therefore, hematuria is not always detected by the eyes. You can see that there is blood in the urine with your eyes, and at least 1 ml of blood is mixed with about 1000 ml of urine, which indicates that the hematuria is more serious, and the cause should be found out as soon as possible.

a) Hematuria**.

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

Common diseases that cause hematuria include various nephritis, urinary tract infections, hemorrhagic cystitis, urinary stones, renal tuberculosis, kidney tumors, kidney and urethral injuries, etc. Hematuria is one of the main symptoms of these disorders.

2) Differential diagnosis of hematuria.

When urination begins with hematuria and the urine is normal in the later segment, it is usually a urethral disease; If urination begins normally and hematuria occurs near the end, cystitis and prostate disease are common; If it is "full hematuria", the blood is dark red, and it is usually caused by kidney disease. Blood in the urine rarely presents with signs of shock.

Hematuria is common in the following conditions:1

Resulting in blood in the urine, it may be caused by many kinds of **. The more common ** are as follows:

1. Urinary tract infection. When urinary tract infection presents with gross hematuria, it is often accompanied by urinary frequency, urgency, and painful urination. In urinalysis, the urine will show that the white blood cells and red blood cells in the urine are markedly elevated. Clause.

2. Urinary tract tumors. Urinary tract tumors often manifest as gross hematuria, that is, gross hematuria occurs without obvious conscious symptoms. Clause.

3. Urinary stones. Hematuria in urinary stones is usually accompanied by a severe episode of renal colic. That is, it is manifested as severe pain in the lower back and abdomen, which can be accompanied by nausea, vomiting and other symptoms. Clause.

4. Trauma of the urinary system, that is, damage to the urinary system caused by trauma, including kidney contusion, urethral contusion, bladder rupture, etc. Gross hematuria may also occur in some systemic disorders, mainly in coagulation disorders; Accidental ingestion of rat poison may also cause gross hematuria; Some people develop rhabdomyolysis after strenuous exercise and may also have blood in their urine.

Common ones are: nephritis, urinary tract infection, urinary stones. You should go to the hospital for further diagnosis.

It is mainly caused by urinary diseases, such as renal tuberculosis, nephritis, urinary tract infection, urinary tract stones, urinary tract tumors, etc. Hematuria accompanied by long-term urinary frequency, urgency, and painful urination is more likely to cause renal tuberculosis; If hematuria is accompanied by swelling of the eyelids, face or body, elevated blood pressure and fever, acute nephritis may be present; For example, patients with hematuria accompanied by severe urinary frequency, urgency, and painful urination are mostly acute cystitis; If urination is not smooth, the urethral opening is not painful, but the naked eye sees light red urine or a trace amount of red blood cells under the microscope, it is mostly prostate inflammation; Hematuria with symptoms of low back pain, sometimes severe paroxysmal low back pain - renal colic - may be kidney or ureteral stones. It's better to go to the hospital for a check-up

It's called hematuria.

**:(1) Inflammation: acute and chronic glomerulonephritis, acute and chronic pyelonephritis, acute cystitis, urethritis, urinary tuberculosis, urinary fungal infection, etc.

2) Stones: Stones in the renal pelvis, ureters, bladder, urethra, and any part of the body, when the stones move, they break the urothelium, which is easy to cause hematuria and secondary infection. Large stones can cause urinary tract obstruction and even kidney damage.

Have a urinalysis check to see if there is a urinary tract infection.

I know there was blood when I pulled. It's a leaky sore.
