Acute Epididymo-Orchitis

Acute Epididymo-Orchitis


Epidemiology of Acute Epididymo-Orchitis

  • Most Common Organism – Chlamydia (Gonococcal epididymitis still prevalent)
  • Develops in 18% of men suffering from Mumps , usually when parotid swelling is waning
  • Mumps epididymitis in absence of parotiditis occurs in infants
  • Other Causes – Enteroviruses , Brucellosis, LGV
  • Escherichia coli is an important cause of nonspecific epididymitis and orchitis in children with congenital genitourinary abnormalities and in older men.
  • Mycobacterium tuberculosis can cause tuberculosis of the epididymis and testes, characterized by granuloma formation.
  • Pseudomonas sp. has been implicated as an important cause of nonspecific epididymitis and orchitis in older men.

Pathogenesis of Acute Epididymo-Orchitis

  • May Follow Uretheral Instrumentation , prostatectomy

Signs & Symptoms (Clinical Features) of Acute Epididymo-Orchitis

  • Scrotal Wall becomes red, edematous , shiny and become adherent to epididymis
  • Orchitis without epididymitis is seen in SYPHILIS
  • In differential diagnosis of epididymo-orchitis & torsion it is important that Elevation of testis in epididymo orchitis relieves pain
  • Acute tuberculous epididymitis – thickened vas

Complication of Acute Epididymo-Orchitis

  • The Main Complication is testicular atrophy which may cause infertility (if B/L) 

Diagnosis & Management of Acute Epididymo-Orchitis

  • Doxycycline for Chlamydial infection, Plenty of fluids, scrotal support and analgesics
