Epididymo-orchitis is an inflammation of the epididymis (the tube which stores and transports sperm) and/or testicle (testis). In adults, epididymo-orchitis is usually due to infection, most commonly from a urine infection or a sexually transmitted infection. A course of antibiotic medicine will usually clear the infection. Full recovery is usual. Epididymo-orchitis complications are uncommon.
Epididymitis is the term for inflammation of the structure responsible for producing, storing, and moving sperm, located close to the testicle. An inflammation of a testicle is called orchitis.
Empirical Cause
Usually as a result of an infection spreading locally from the bladder (urinary tract infection – UTI) or the urethra (STI).
Origins
Most typically, a sexually transmitted infection causes it in those under 35.
When one is over 35 years old, it is more likely to have a UTI complication (i.e., gram-negative enteric bacteria). Men who have insertive anal sex can also contract enteric pathogens sexually. The most crucial diagnostic in every man to rule out is testicular torsion. Urgent referral should be undertaken if a prostate tumor is suspected. The mumps have returned to the UK in recent times, particularly among individuals who have not received the vaccination.
Usually just one side is affected by discomfort and edema. Though one third of mumps patients do not develop parotitis, urethral discharge ± dysuria (if caused by a STI); signs of UTI (frequency, pyrexia); headache, fever, and parotid enlargement may precede unilateral testicular swelling by 7–10 days.
Scrotal erythema and oedema, palpable discomfort, epididymal swelling, urethral discharge, subsequent hydrocoele, pyrexia.
Reduced fertility is caused in 13% of men with bilateral illness by complications including hydrocoele, abscess and testicular infarction (rare), infertility or subfertility, and testicular atrophy (post-mumps).
Examinations and diagnosis
If any suspicions of this diagnosis exist, testicular torsion should be ruled out first and referral should be made as soon as possible. Always rule out STIs; if one is available, a gram-stained urethral smear may reveal urethritis; NAAT for C. trachomatis and N. gonorrhoeae Gram-negative intracellular diplococci; microscopy and culture of a midstream urine specimen; urine dipstick for nitrites, leucocytes, and blood. Men who have a confirmed UTI should all be sent for further urinary tract evaluation. Should there be suspicions of tuberculosis, three early morning urines (along with CXR, etc.) should be taken. Immunoglobulin M/G serology is used to diagnose measles.
General management: rest, scrotal support, analgesia (including NSAIDs). When a sexually transmitted cause is suspected or confirmed, advise them to abstain from SI until they and their partners have finished treatment. Provide the condition’s textual information.
Cure: Every patient should get empirical antibiotic treatment (before findings are available). The selected regimen need to be in line with the antibiotic sensitivity in the area. Those with signs of bacteraemia or serious illness should think about receiving inpatient hospital care.
Partner Notification (PN): Unless a non-STI reason is established, all current partners should be tested and provided with epidemiological treatment.
Should symptoms increase or there be no improvement after three days, the diagnosis should be revisited. Assess once more after two weeks to make that the patient is following the treatment, has PN, and is improving clinically.
sexually acquired reactive arthritis
Reactive arthritis (ReA), sometimes known as sexually acquired reactive arthritis (SARA), is a seronegative inflammation of the synovial membrane brought on by an infection at a distant site. SARA is the term for the trigger if it is a STI. This covers the trinity of arthritis, urethritis, and conjunctivitis known as Reiter’s syndrome.
Aetiology: Most often (35–69%) linked to chlamydia infection; also associated with Ureaplasma urealyticum and Neisseria gonorrhoeae. Happens ten times more often in men than in women (however underdiagnosis in women may happen).
Pathogenesis: seems to be an immunological reaction against bacteria in the vagina. There can be a history of spondyloarthritis in the family.
Being HLA-B27 gene positive greatly increases susceptibility.
Signs and symptoms: Usually appear 30 days after SI. 10% of them will also experience fever, exhaustion, and malaise as systemic symptoms. There may be urethritis, cervicitis, epididymitis, tenosynovitis with crepitus (particularly fingers), and circinate balanitis.
Complications: Most people find that SARA is self-limiting. The first episode lasts on average four to six months. Recurrent bouts will affect half of people. The main cause of complications is aggressive arthritis, which strikes HLA-B27 positive individuals more often. For 15% of people, erosive injury to their joints results in locomotor impairment. Anterior uveitis complications include blindness and cataract development.
The diagnosis is clinical. Ask about symptoms of the skin, eyes, and joints in those who have urethral symptoms. In those exhibiting SARA symptoms, find out about new sexual partners and STI symptoms.
Essential tests include a urinalysis, ESR, FBC or CRP, and a complete STI screen. Depending on the clinical picture, LFTs, renal function tests, and X-rays of the injured joints could be helpful. As with plasma urate for gout, exclusion tests for other causes of arthritis may be recommended.
General management: use of NSAIDs and rest. Suggest that until therapy and PN are over, one refrain from SI, especially oral sex.
Treatment: Conventional antibiotic regimens for particular genital infections that have been identified. Longer antibiotic treatments have a controversial role to play. Manage the patient ideally together with dermatology, ophthalmology, and rheumatology. Treatments for arthritis include rest, exercise, and frequent NSAIDs (determine risk of gastrointestinal bleeding).
Single joints may benefit from intra-articular corticosteroid injections. It is recommended to start second line treatments in consultation with a rheumatologist.
The look back time for PN (Partner Notification) is determined by the diagnosed genital infection.
Follow-up: according to identified STI. For extra-genital symptoms, specialists should decide on follow-up.
Acute bacterial prostatitis
Prostatitis caused by bacteria acutely a rare but possibly dangerous bacterial illness brought on by enterococci or Escherichia coli, two urinary pathogens. Men who present with systemic symptoms (e.g., fever, myalgia, rigors) and signs of voiding the urine should be suspect. While you wait on the urine culture findings, treat with antibiotics and analgesics; for example, take 500 mg of ciprofloxacin twice a day for 28 days.
