Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - The onset of scrotal pain typically occurs over hours and is often referred to the ipsilateral inguinal canal or lower abdominal quadrant. Recent urinary tract instrumentation or urinary tract infection is a risk factor. Early in the course, a tender, indurated, edematous epididymis is palpated separately from the nontender testicle. Late presentations will have generalized scrotal swelling and tenderness, making examination and differentiation more difficult. The urinalysis reveals pyuria or bacteriuria half of the time, and the peripheral white blood cell count is frequently elevated. Patients can present with fever and signs of sepsis. Approximately half the time, the epididymis and adjacent testicle will be inflamed, which is termed epididymo-orchitis.
