The third most common cause of blood in the urine with around 8% is bladder tumors (bladder carcinoma).
Causes of blood in the urine can be varied and mostly lie in the Kidneys or the urinary tract.
Common and harmless causes are, for example, menstrual blood in women, the consumption of beetroot, which can also color the urine red, or slight bleeding after an operation or an intervention on the pelvic floor or the urinary tract.

Blood in the urine in itself is a symptom of various diseases. The clinical picture depends on the underlying disease.
Generally speaking, it can be said that inflammation is usually associated with fever, Pain and increased Inflammation values (CRP value, White blood cells = Leukocytes) in the blood. The presence of a Tumor fever, night sweats and weight loss (B symptoms) Show.

If blood coagulation is disturbed, the patient may have an increased tendency to bleeding in addition to the blood in the urine (for example of the skin and mucous membranes, prolonged Menstruation).
Other symptoms that can occur with blood in the urine are loss of protein (proteinuria) and the existence of white blood cells (leukocytes).
Blood in the urine, in combination with painful urination, speaks primarily for one Urinary bladder infection and occurs mainly in women. When bacteria get into the urethra, they can rise up into the bladder and cause painful inflammation.
If the infection is not treated adequately, the bacteria can continue to rise and cause inflammation of the renal pelvis, which is also high fever, Flank pain and Exhaustion goes hand in hand.
Both clinical pictures should be treated with antibiotics.
Another cause of painful urination and blood in the urine is kidney and ureteral stones. If the sharp stones move through the urinary tract, severe pain and tissue damage can occur over and over again, which can lead to a leakage of blood.
With small urinary stones one can walk away spontaneously, with painkillers and antispasmodics (e.g. Buscopan®), wait and see.
Larger stones can be sent by Shock wave lithotripsy (ESWL) or removed under a ureter mirror. Sufficient exercise, plenty of drinking (approx. 2.5 liters), as well as avoiding animal fats and a diet high in protein.

First, if blood appears in the urine, an anamnesis (inquiring about the medical history) is taken and then the patient is physically examined. Particular attention is paid to the examination of the kidney bearings or flanks, the bladder region and the genitals.
In addition, basic diagnostics are carried out, which include the following examinations:
The general laboratory test includes values relating to kidneys, blood clotting and anemia (anemia). The urine laboratory includes, among other things, the detection of various cells including their morphology and protein.
If an excretory urography or a computed tomogram cannot be performed, for example due to a contrast agent allergy, an alternative is magnetic resonance imaging of the abdomen (MRI abdomen).

Further diagnostic examinations can be arranged for specific questions about the cause of the bloody urine. This includes examining the cells in the urine (Urine cytology), radiological imaging of the ureter using a contrast medium (retrograde pyelography), a ureteroscopy (Ureterorenoscopy), a vessel representation (Angiography) and a kidney sample with subsequent microscopic tissue examination (kidney biopsy).
A pelvic exam should also be performed to determine the cause of the blood in the urine.

The most common causes of blood in the urine in women are Menstrual blood or Cystitis. But also Cysts, Polyps or Genital organ tumors can lead to bloody urine. Some rheumatic diseases that occur much more often in women than in men, such as systemic Lupus erythematosus, can also lead to blood in the urine if the kidneys are involved.
$config[ads_text1] not foundIn men, common causes are kidney and ureter stones, inflammation of the prostate, prostate cancer, or tumors of the kidney and urinary tract. In particular, tumors of the urinary tract, urothelial carcinoma, are associated with painless macrohematuria (visible, bloody discoloration of the urine) and should definitely be examined by a doctor.
If blood appears in the urine, the underlying condition needs treatment.
Cancer is treated with surgery, chemotherapy or radiation, depending on the stage and tissue of origin.
In the event of inflammation or infection, the patient receives depending on the pathogen Antibiotics, sometimes in combination with, for example, pain relieving medication.
Stones causing the blood in the urine are crushed (Lithotripsy) or surgically removed, blood coagulation disorders are treated in severe forms by substituting the missing or defective blood components (coagulation factors, platelets, etc.). Drugs that cause the bloody urine are stopped.
The prognosis depends on the underlying disease.
"Blood in the urine" means the occurrence of red blood cells (erythrocytes) in the urine, which is a symptom of various diseases. Depending on whether the urine is visibly reddish in color, a distinction is made between micro and macro hematuria (see causes of blood in urine). In the former, such a color cannot be seen with the naked eye. Diseases that cause blood in the urine affect the kidneys, the lower urinary tract (ureters, urethra), the urinary bladder or the prostate, with inflammation, stones or tumors in these structures usually causing the bloody urine. Non-pathological reasons for the red color of the urine can be the female menstruation, certain foods (beetroot) or medication.
In addition to anamnesis and physical examination, the diagnosis is mainly based on blood diagnostics including urine diagnostics, imaging procedures (ultrasound, excretory urography, CT) and cystoscopy (Cystoscopy). The underlying disease, which also determines the prognosis, is treated with blood in the urine.
