[Duplex echography in acute scrotum. Diagnostic possibilities].

Acute scrotum is a frequent reason for consultation at the urological emergency service. The most common causes, apart from trauma, are acute orchiepididymitis, torsion of the hydatids of Morgagni and torsion of the spermatic cord. Apart from a detailed examination of patient history and a careful physical examination, few diagnostic techniques can be utilized. To date, only the Doppler ultrasound has proved useful in corroborating the suspicion of vascular involvement, although this technique is very limited. With the availability of the duplex ultrasound, the possibility of making the differential diagnosis in the acute scrotum is enhanced. This technique permits morphological and functional assessment and avoids unnecessary exploration surgery within the scrotum.
