The first-line treatment for low-flow priapism is drawing blood from the corpus cavernosum. The penis is numbed, aspirated for blood, and then irrigated with saline and drugs called alpha-agonists (if necessary) injected into the corpus cavernosum. This procedure has a high rate of success and can be repeated in time.
Second-line treatment typically refers to penile surgery. It should be used in case of emergency, only after conservative and first-line treatments have failed.
There are two main types of surgery for low-flow priapism: penile shunt surgery and penile prosthesis implantation.
