It's pink. What's going on?

The patient's urine is pink and considered to be hematuria, which is normally caused by urinary system infection, urinary system stones, urinary system tumors, urinary system trauma, etc. If the patient has urinary system infection, urinary system stones, due to inflammatory stimulation, stone incarceration and other factors, the urinary tract mucosa shows rupture, causing red blood cells to enter the urine, thus causing the urine color to turn pink. If the patient has a urinary system tumor, the tumor growth to a certain extent, the capillary on the surface of the tumor may show local mucosal rupture, thus causing urinary tract bleeding. Urinary system trauma at the beginning of the injury, will also cause urine is pink, as the injury gradually healed, urine color will gradually deepen, or even black.
