[Usefulness of Doppler-color ultrasonography and identification of resistance indexes as early indicators of testicular infarction secondary to orchiepididymitis]. / Utilidad de la ecografía Doppler-color y la determinación de los índices de resistencia como indicadores precoces de infarto testicular secundario a orquiepididimitis.

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.

[Renal vein partial thrombosis in 3 recipients of kidney transplantation]. / Trombosis parcial de la vena renal en tres pacientes trasplantados.

OBJECTIVE: To report on three patients with partial graft renal vein thrombosis diagnosed by ultrasound. METHODS: The vascular complications diagnosed by ultrasound in 400 transplants performed from 1995-1998 were reviewed. RESULTS: Three patients with partial graft renal vein thrombosis were found. Two patients were treated with anticoagulant therapy. No thrombosis could be detected in all three patients on subsequent US control evaluation. CONCLUSIONS: Unlike complete thrombosis, partial graft renal vein thrombosis presents late, without significant clinical features and can be managed conservatively.
