[Help] I am 30 years old, and two years ago I suffered a pelvic fracture, urethral rupture and hemorrhagic shock as a result of a car accident, and now I can urinate freely after rescue treatment. In the past two years, I have been going around to seek medical help, and I have not seen any effect after taking some Chinese herbal medicine for kidney aphrodisiac and western medicine for impotence. [Comment] Pelvic fractures can often cause erectile difficulties, which is medically known as traumatic erectile dysfunction, generally caused by damage to the small arteries that provide blood to the penis for erection or the nerves that govern penile erection. With the increase in car accidents and work-related accidents in recent years, the occurrence of traumatic erectile dysfunction is on the rise. Damage to erectile function can often cause physical, psychological and personality disorders to men, greatly reducing the quality of life and bringing great pain to families. [Countermeasures] The treatment of erectile dysfunction caused by trauma is difficult, and simple medication is not yet effective. For example, intracavernosal vasoactive drug injection may not be effective. Therefore, we should first apply some special examination means, such as dual-function Doppler ultrasound combined with intracavernosal vasoactive drug injection examination to understand the blood flow of penile artery, such as can find the insufficient blood supply of penile artery. Internal pubic arteriography can clearly show the degree of penile artery damage, such as arterial dissection and stenosis. Nerve function tests can be performed to understand the presence or absence of nerve damage. In patients with a purely affected arterial supply, microsurgical techniques are applied to reestablish bypass blood flow channels by bypassing the damaged artery to increase the perfusion pressure and blood infusion to the penile corpus cavernosum, thus making it possible to restore natural erection and achieve a permanent cure after surgery without the help of any other method. Patients with nerve damage may be more difficult to treat, and the ultimate remedy may be a penile prosthesis implant. Trauma-induced impairment of the erectile function of the penis can be revitalized by vascular or prosthetic surgery.
