Epididymitis

Summary

Epididymitis is an inflammation of the epididymis that is commonly associated with genitourinary tract infections. The typical presentation involves a gradual onset of pain and swelling of the affected side of the scrotum as well as a positive Prehn sign. Epididymitis is a clinical diagnosis, but testicular torsion should be excluded by ultrasound because it has a similar presentation and is a surgical emergency. Treatment involves prompt empiric antibiotic therapy, scrotal elevation, and nonsteroidal anti‑inflammatory therapy to prevent abscess formation and possible infertility.
