Hello and welcome to the Zero to Finals podcast.

My name is Tom and in this episode I'm going to be talking to you about Epidididymocytis.

And you can find written notes on this topic at zero definals.com slash epididimo or chitis

or in the urology section of the Zero to Fin finals surgery book. So let's get straight into it.

Epidididymitis is inflammation of the epididymis. Orchitis is inflammation of the testicle.

Epidididemoe orchitis is usually the result of infection in the epididymus and the testicle on one side.

Let's talk about some very basic anatomy.

At the back of each testicle is the epididymus.

Sperm are released from the testicle into the head of the epididymus, which is connected to the top of the testicle.

The sperm travel through the head, then the body, and then to the tail of the epididymus.

The epididymus is where the sperm are matured and stored until they're eventually released into the vast deference.

Let's talk about the causes of epididymusisone. and stored until they're eventually released into the vast deference.

Let's talk about the causes of epididimo-alkitis.

The key causative pathogens are E. coli, chlamydia trachomatis,

Nyseria gonorrheahea and mumps.

A tom tip for you, think of mumps in patients with parotid gland swelling and orchitis.

Mumps tends only to affect the testicle sparing the epididymus.

Mumps can also cause pancreatitis.

Let's talk about the presentation. Epidididymorchitis typically presents with a gradual onset over minutes to hours with unilateral testicular pain, a dragging or heavy

sensation in the testicle, swelling of the testicle and swelling of the epididymus, tenderness on palpation,

particularly over the epididymus, urethral discharge, which should make you think about

chlamydia or gonorrhea, and systemic symptoms such as fever and potentially sepsis.
