Black urine in women indicates that there is blood in the bladder and possibly blood clots, suggesting that there is bleeding in the woman’s urinary system and the bleeding may be more. It is recommended that in this case one must drink a lot of water and urinate more to promote the discharge of blood urine from the body. At the same time, ultrasound examination of kidney, ureter and bladder should be done under the condition of holding urine, and the cause of hematuria must be found. The most important thing about hematuria is to exclude urinary tract tumors. Only when we find out whether there are urinary tract tumors, we can consider simple diseases such as urinary tract inflammation, and ultrasound can find out whether there are urinary tract stones. For women with hematuria, it is important to do anti-infection treatment.
