Is follow-up ultrasound necessary after acute epididymitis? A retrospective analysis from a large university hospital

Epididymitis can be diagnosed and treated correctly without scrotal ultrasound in the majority of cases. However, the risk of underlying testicular cancer should be kept in mind. Patients below 50 years of age without bacteriuria and patients with persistent symptoms after antibiotic treatment should be referred to an urologist for a re-evaluation or for a follow-up ultrasound.
