clinical picture
1, urine color change
The main manifestation of hematuria is the change of urine color. In addition to the normal color of hematuria under the microscope, gross hematuria shows different colors according to the amount of bleeding. The urine is reddish like a meat washing water sample, suggesting that the blood content per liter of urine exceeds 1mL. When bleeding is serious, urine can be blood-like. When the kidney bleeds, the urine and blood are mixed evenly, and the urine is dark red; Urine in the bladder or prostate is bright red, and sometimes there are blood clots.
2. Abnormal urine segmentation
Observe the color of the whole urine in sections, such as the urine three-cup test, and use three clean glasses to leave the initial, middle and final urine for observation. If hematuria in the initial section indicates that the lesion is in the urethra; Terminal hematuria suggests that the bleeding site is in the prostate and seminal vesicle of bladder neck, triangle or posterior urethra. All three stages of urine are red, that is, hematuria, suggesting that hematuria comes from kidney or ureter.
