The main cause of bifurcation is local edema or hyperplasia of the mucous membrane at the urethral opening, mainly due to local friction at the urethral opening or due to temperature changes, causing irritation of the local skin and mucous membrane. There are also cases where the recent intake of spicy and stimulating food causes localized edema in the mucous membrane of the urethra, which can lead to bifurcation of urination. It may also be due to urinary tract infections, such as glansitis, which is mainly seen in men with long foreskin, and when there is an increase in foreskin scale, it will stimulate the local urethral orifice, resulting in local edema of the urethra and causing bifurcation of urination. There are also cases in which women experience edema at the urethra due to violent impact after sexual intercourse. As long as the patient keeps drinking a lot of water, the urethra plays a good flushing effect to prevent the infection of pathogenic bacteria, at the same time should carry out physical activities, maintain a good lifestyle, generally the edema and inflammation will subside.
