Dorsal deep penile vein encapsulation is a surgical procedure used clinically to treat venous erectile dysfunction in men. The surgical procedure of dorsal deep penile vein encapsulation is to incise the skin on the dorsal side of the penis, locate the dorsal deep penile vein located on the surface of the tunica albuginea, and free it in a 1-2 cm section, then incise the tunica albuginea, and encapsulate this free section of the vein underneath the tunica albuginea. Through the deep dorsal penile vein encapsulation, the venous return of the penis can be reduced, which has a certain therapeutic effect on erectile dysfunction caused by hemodynamic disorders of the penis, but the long-term effect of this procedure is poor. However, there is a risk of injury to the penile artery and the dorsal penile nerve during the procedure, which may lead to bleeding and postoperative hypesthesia of the glans penis; postoperative decrease in venous return to the penis may result in penile edema, and there is an increased risk of infection. Therefore, if you need to perform deep dorsal penile vein encapsulation, you must go to a regular hospital for treatment, and do a good job of postoperative hygiene and wound care of the penis and perineum to reduce the occurrence of complications.
