title: [Penile ultrasonography. Characteristic velocimetric feature in the maximal erection phase in healthy subjects].
abstract: BACKGROUND
  A peculiar finding from penis eco color-Doppler, detected in healty subjects with erection dysfunction, is described.
  
  
  METHODS
  385 patients with erection dysfunction were studied, by using duplex scan with color Doppler, 85 of these patients normal Regiscan test were chosen and patients with Induratio penis plastica or hormonal disorder were excluded.
  
  
  RESULTS
  A "reverse" flow during the entire diastolic phase was detected in 58 normal patients (68%) with age < of 41 years.
  
  
  CONCLUSIONS
  In the evaluation of healthy subjects with erection dysfunction, the presence of a complete "reverse" diastolic flow is indicative of a venous reflux block, that may represent an important pathogenetic mechanism in this specific setting.
