It may be as little as hematuria, and as gross hematuria. Blood in the urine is almost always accompanied by pain. Red blood cells in urine fresh source of bleeding - minor injuries of the renal pelvis and ureter. They are always accompanied by pain, especially when the stone is small in size and with a rough surface, but movable. He often injure the soft tissue of the ureter than large stones. With the removal of calculi hematuria ceases. Special treatment in this case is not required.
In infections of the genitourinary system, such aspyelonephritis, the source of bleeding capillaries become inflamed and swollen walls of the renal pelvis and ureteral orifice. Bleeding may be in the form of gross hematuria or microscopic hematuria. Thus detected in urine and bacteria which caused inflammation. With the elimination of inflammation is stopped and discharge of blood in the urine. In the treatment of antibiotics used, but it requires a preliminary analysis of the microbial flora on sensitivity to them.
Tumors of the kidneys and urinary tract. Hematuria is observed when the tumor compresses the surrounding soft tissues, blood vessels, the urinary tract, and the decay of the tumor.

Red blood cells in urine stale from long contact with the urine, they are leached and deformed. Hematuria in glomerulonephritis is always accompanied by the presence of protein in the urine. With the reduction of inflammation and decreases hematuria.
Hematuria not associated with diseases of the genitourinary system
It may be observed in blood diseases,liver failure. The color of blood stained urine when taking certain medications: amidopirina, phenyl salicylate, rifampicin, in certain diseases: hemophilia, idiopathic thrombocytopenic purpura, thrombocytopenia.
The source of the bleeding can be differentdepartments urinary tract. To define it is possible to carry out the so-called trehstakannaya sample. The patient was offered alternately to urinate in three vessels. If only the first portion of urine colored with blood, and the remaining portion of the normal color, cause damage to the urethra.
If in the first portion have blood urine, andthe next two portions stained with blood, the source of bleeding can damage the bladder neck, posterior urethra or prostate. If the urine in all portions painted with blood, the probable causes are kidney cancer, bladder cancer, prostate cancer, hemorrhagic cystitis.
