Penile venous fistula can be treated by ligating a vein. Penile venous fistula is a condition in which the corpus cavernosum in the penis is damaged, causing blood to leak to the glans or other blood vessels during penile engorgement. Abnormalities in the venous system of the cavernous body of the penis can lead to a shunting of blood during an erection, resulting in an inability to have a normal or inadequate erection. Surgical ligation of the veins can be performed to stop the return of blood from the cavernous veins and to help with penile erection. In addition, the venous fistula can be found through intervention and improved using embolization to achieve the purpose of treatment. Daily attention should be paid to the local care of the wound, to keep the private parts clean and clean, to prohibit sexual intercourse during the recovery period, and to carry out regular reviews to observe the recovery situation.
