HEMATURIA - excretion of blood in the urine. If the presence of blood in the urine is determined by the naked eye, talk about gross hematuria; if red blood cells are detected only by microscopic examination, they speak of microhematuria. Hematuria is a symptom of many diseases of the urinary system - tumors and tuberculosis of the kidney, pyelonephritis, urolithiasis, hemorrhagic cystitis, tumors of the bladder. In addition, hematuria can be the result of a coagulation disorder in diseases of the liver, blood scurvy, as well as an overdose of anticoagulants. The so-called glass test helps to correctly evaluate this symptom: separate urine samples are taken from the patient during urination - at the beginning, in the middle and at the end of urination. The presence of visible blood (gross hematuria) only in the first portion of urine (initial hematuria) indicates damage to the urethra (trauma, polyps, cancer , gonorrhea , syphilis). The presence of blood only in the last portion (terminal hematuria) indicates a lesion of the back of the urethra, bladder neck, prostate gland, seminal vesicles. Blood in all three portions (total hematuria) can be observed with diseases of the bladder, renal pelvis and kidney parenchyma. In all cases hematuria patient must be sent to the urologist.
