title: [Usefulness of Doppler-color ultrasonography and identification of resistance indexes as early indicators of testicular infarction secondary to orchiepididymitis].
abstract: The testicular infarction can be a rare complication of the orchiepididymitis. The ultrasonography appearance of the partial infarctions creates confusion with expansive intratesticular processes. We present three cases of focal testicular infarction associated with orchiepididymitis, stressing the usefulness of the Color doppler sonography for detecting the avascular nature o these lesions. The determination of de indeces of resistance (IR) in the doppler spectrum of intratesticular arteries showed a highly increased vascular resistance in respect of the healthy testicle. In patients with grave orchiepididymitis vein drainage can be affected due to compressive edema or to thrombosis, causing the raising of the resistance indeces. Acknowledging the avascular resistance of the focal post-orchiepididymitis infarction we can prevent unnecessary orchiectomy.
