Torsion of the testis diagnosed by ultrasound

An ultrasonic method to diagnose acute testicular torsion is presented. With the doppler principle the presence of absence of intratesticular arterial pulsation can be demonstrated. In 5 patients with acute testicular torsion and 10 patients with epididymitis a correct ultrasonic diagnosis was made. In long-standing torsions some arterial pulsation may be present.
