When there is blood in the leucorrhea after urination, it may be caused by bleeding in the urine, bleeding caused by hemorrhoids, or bleeding caused by diseases of the cervix. There are many causes of cervical bleeding, such as cervical mucositis or cervical polyps, which can cause blood in the leukorrhea. In addition, hemorrhoids in the anus can cause bleeding if they rupture or fissure, and the specific treatment plan will be decided based on the specific results of the examination. In case of blood in urine, further ultrasound of the bladder and ureters should be performed to find out if the bleeding is caused by kidney stones or urinary tract infection. If the bleeding is caused by a cervical polyp, prompt removal of the cervical polyp should be performed. If the bleeding is caused by hemorrhoids, see an anorectologist for specific examination and treatment.
