The most common clinical cause of leukorrhea is vulvovaginal pseudomonal yeast disease caused by Candida infection, which not only shows a tofu-like discharge, but also vulvar itching, vulvar redness and swelling, and some people also have frequent and urgent urination. The itching of the vulva can be very painful and make the patient restless. It is recommended to rinse the tissue-like discharge with 5% sodium bicarbonate and insert mycobacterium suppositories or dacrynic acid soft capsules into the vagina until the clinical symptoms disappear, and then recheck the white belt routine 3-7 days after stopping the medication.
