Epididymitis
Definition:
Epididymitis is an inflammation of the epididymis, the tubular structure that connects the testicle with the vas deferens. Causes, incidence, and risk factors:

Acute epididymitis causes swelling of the scrotum, pain in the testicles, and sometimes a fever of up to 6 weeks duration or less (usually with a gradual onset over several days). If not treated, or in some other cases, the condition can become chronic. In chronic cases, there is usually no swelling, but simply pain. The incidence is approximately 600,000 cases per year. The highest prevalence is in young men 19 to 35 years of age. The disorder is a major cause of hospital admissions in the military (causing approximately 20% of admissions). Epididymitis is caused by spread of infection from the urethra or the bladder. The most common organisms involved in the condition in young heterosexual men are gonorrhoea and chlamydia. In children and older men, typical uropathogens, such as coliform oraganisms (E. coli), are much more common. This is also true in the case of homosexual men. Mycobacterium tuberculosis (TB) can manifest also as epididymitis. "Beadlike" irregularities along vas deferens are the characteristic sign of this condition. Other bacteria (such as Ureaplasma) may also cause epididymitis. A non-infectious cause of epididymitis is the use of anti-arrhythmic medication, amiodarone. In this case, the inflammation is limited to the head of the epididymis and does not respond to anti-microbial therapy. The treatment is dosage reduction or change of medications. An increased risk is associated with sexually-active men who are not monogamous and do not use condoms. Men who have recently had surgery or have a history of structural problems involving the genito-urinary tract are also at increased risk (regardless of sexual behaviors). Other risk factors include chronic indwelling urethral catheter use and being uncircumcised.
