Orchitis

Orchitis is inflammation of the testes.[1] It can also involve swelling, pains and frequent infection, particularly of the epididymis, as in epididymitis. The term is from the Ancient Greek ὄρχις meaning "testicle"; same root as orchid.

Signs and symptoms

Symptoms of orchitis are similar to those of testicular torsion. These can include:

Causes

Orchitis can be related to epididymitis infection that has spread to the testicles (then called "epididymo-orchitis"), sometimes caused by the sexually transmitted diseases chlamydia and gonorrhea. It has also been reported in cases of males infected with brucellosis.[2] Orchitis can also be seen during active mumps, particularly in adolescent boys.

Ischemic orchitis may result from damage to the blood vessels of the spermatic cord during inguinal herniorrhaphy, and may in the worst event lead to testicular atrophy.[3]

Diagnosis
Doppler ultrasound of the scrotum, in the axial plane, showing orchitis (as part of epididymo-orchitis) as hypoechogenic and slightly heterogenic left testicular tissue (right in image), with an increased blood flow. There is also swelling of peritesticular tissue.
  • Blood – ESR high
  • Urine – Cultural & Sensitivity test
  • Ultrasound scanning

Treatment

In most cases where orchitis is caused by epididymitis, treatment is an oral antibiotic such as cefalexin or ciprofloxacin until infection clears up. In both causes non-steroidal anti-inflammatory drugs such as naproxen or ibuprofen are recommended to relieve pain. Sometimes stronger pain medications in the opiate category are called for and are frequently prescribed by experienced emergency department physicians.

Other animals

Orchitis is not rare in bulls and rams. It has also been described in roosters.[4]
