There are many causes of hematuria in women, including urinary tract infections, tuberculosis, stones, tumors, nephritis, adenocystitis, IgA nephropathy, etc. Among them, urinary tract infections have the highest probability of occurrence. As the female urethra is shorter, wider and straighter, it is very easy to have retrograde infection. When urinary tract infection occurs, patients often have frequent urination, urgent urination, painful urination, burning sensation in urine, hematuria, etc. They need to drink more water, urinate more often, pay attention to rest, abstain from spicy and stimulating food, and choose sensitive antibiotics for antibacterial and anti-inflammatory treatment. After the inflammation disappears, the phenomenon of hematuria will disappear on its own.
