Management of chronic orchialgia of unknown etiology.

The treatment of patients with chronic unilateral or bilateral orchialgia, defined as intermittent or constant testicular pain of greater than 3 months and of unclear cause, is difficult. This pain significantly interferes with the daily activities of the patient. We have seen 12 patients with chronic orchialgia of unknown etiology and each had a normal history, physical examination and normal scrotal sonogram. Three patients were treated with nonsteroidal anti-inflammatory drugs and obtained partial pain relief. Three patients underwent spermatic cord nerve blockade using a combination of 1% lidocaine and 40 mg methylprednisolone and experienced partial pain relief. Four patients underwent inguinal orchiectomy after failing conservative management: three reported complete relief of pain, and the other partial relief. Two patients had bilateral transrectal injections of local anesthetic (5 ml bupivacaine) and methylprednisolone into the region of the pelvic plexus under transrectal ultrasound guidance. They were successfully treated with this injection technique. On the basis of our results, we recommend transrectal blockade of nerves from the pelvic plexus or inguinal orchiectomy as the procedure of choice for patients in whom medical treatment fails.
