Study Notes
Age Factors and Pathogens
- Men aged 14 to 35 years are most affected by epididymitis and orchitis.
- Common pathogens in this age group include Chlamydia trachomatis and Neisseria gonorrhoeae.
Physical Findings
- Typical findings include swollen, tender epididymis or testis in normal anatomical position with intact ipsilateral cremasteric reflex.
Prevalence and Causes
- Epididymitis is more common than orchitis.
- The primary cause of intrascrotal inflammation is epididymitis.
- Infections causing epididymitis in the 14-35 age group are predominantly from Neisseria gonorrhoeae and Chlamydia trachomatis.
- For those younger than 14 or older than 35, common urinary tract pathogens like Escherichia coli are typically responsible.
Risk Factors
-
Risk factors for all men include:
- Sexual activity
- Strenuous physical activity
- Bicycle or motorcycle riding
- Prolonged sitting (e.g., during travel or sedentary jobs)
- In men over 35 and prepubertal boys, risk factors include:
- Recent urinary tract surgery or instrumentation
- Anatomic abnormalities (e.g., prostatic obstruction in older men, posterior urethral valves, meatal stenosis in boys)
Viral Infections and Orchitis
- Mumps is the most common cause of viral orchitis, which presents with abrupt unilateral scrotal pain and swelling.
- Orchitis associated with mumps generally appears 4 to 7 days after parotitis.
Torsion and Diagnosis
- Torsion of the appendix testis typically occurs in boys aged 7 to 14 years, rarely after age 20.
- Tenderness in the spermatic cord suggests epididymitis.
- A “blue dot” sign presents as bluish discoloration on the scrotal wall, indicative of infarction and necrosis.
Reflexes and Signs
- Cremasteric reflex is elicited by stroking the skin of the upper medial thigh, resulting in ipsilateral testis elevation in normal conditions.
- The cremasteric reflex is present in epididymitis and orchitis but absent in testicular torsion.
- Prehn's sign indicates relief of pain with elevation of the testis, typically seen in epididymitis.
Ultrasound Findings
- A normal testicle showing decreased Doppler wave pulsation suggests torsion.
- An enlarged, thickened epididymis with increased Doppler wave pulsation indicates epididymitis.
Treatment and Follow-up
- Antibacterial medications are unnecessary for viral orchitis; most cases resolve spontaneously within 3 to 10 days.
- Recommended follow-up is 3 to 7 days post-evaluation to check clinical improvement and for testicular mass presence.
- Pain management typically improves within 1 to 3 days, but full resolution of induration may take 2 to 4 weeks.
Additional Recommendations
- Prepubescent boys with epididymitis require a urology referral due to a high incidence of urogenital abnormalities.
- Men over 50 should be evaluated for urethral obstruction due to prostatic enlargement.
Age Factors and Pathogens
- Men aged 14 to 35 years are most affected by epididymitis and orchitis.
- Common pathogens in this age group include Chlamydia trachomatis and Neisseria gonorrhoeae.
Physical Findings
- Typical findings include swollen, tender epididymis or testis in normal anatomical position with intact ipsilateral cremasteric reflex.
