Definition of Mumps Orchitis
Mumps orchitis is an acute viral orchitis as a complication of epidemic parotitis.
Mumps orchitis develops in 30% of patients with mumps after puberty
Etiology of Mumps Orchitis
Mumps virus is a paramyxovirus with a single-stranded RNA.
Signs and Symptoms
- Incubation period: 14–25 days
- Fever, headache
- parotid inflammation (more common bilateral), cloudy saliva
- Orchitis: the scrotal symptoms occur after 4–6 days with a painful testicular swelling, in 10–30% bilateral.
- Spontaneous improvement of symptoms after 1–2 weeks
Diagnostic Work-Up of Mumps Orchitis
- Ultrasound and Doppler-Sonography of the testis
- In cases of clinical doubt about the diagnosis, serological diagnosis of mumps is possible.
Differential Diagnosis of Orchitis
- Septic spread of bacterial diseases (typhoid fever, brucellosis, urogenital tuberculosis
- Continuous bacterial spread of bacterial epididymitis
- Viral infections (mumps)
Treatment of Mumps Orchitis
- Bed rest
- Testicular elevation and cooling
- Non-steroidal anti-inflammatory drugs (e.g. diclofenac)
Leuprorelin (Vicari and Mongioì, 1995) and interferon-α (Ku et al, 1999) was successfully used to treat mumps orchitis and to prevent testicular atrophy.
Prognosis of Mumps Orchitis
- In bilateral disease, the development of testicular atrophy with the risk of infertility is possible.
- Hypergonadotropic hypogonadism is possible in severe bilateral mumps orchitis.
