Torsion of the Testis Diagnosed by Ultrasound
In acute scrotal swellings the differential diagnosis between epididymitis and torsion of the testis is important since torsion needs immediate operation and detorsion. With uncertain clinical diagnosis surgerv is therefore performed. In order to avoid unnecessary surgery on an inflamed epididymis a precise, rapid and atraumatic method for the diagnosis of a torsion has been introduced. Bv using the Doppler principle, the intratesticular pulsations are registered. Compared to the nondiseased opposite testis a torsion shows no Doppler sounds whereas an epididymitis presents increased Doppler sounds. In five patients with a testicular torsion and ten patients with epididymitis a correct ultrasonic diagnosis was made.
