title: The correlation of end-diastolic flow velocity and cavernosometry results in the diagnosis of venous leakage.
abstract: OBJECTIVE
  Cavernosometry is a conventional and reliable method used in the diagnosis of caverno-venous incompetence. Recently, cavernosal artery end-diastolic blood flow velocity more than 5 cm/sec during the rigid phase and after 10 minutes with duplex ultrasonography has been considered as veno-occlusive dysfunction.
  
  
  METHODS
  Fifteen patients with erectile dysfunction aged 20 to 56 years (mean age 35.8) were evaluated by dynamic infusion cavernosometry and duplex ultrasonography which measured end-diastolic blood flow velocity during the rigid phase of erection and after 10 minutes.
  
  
  RESULTS
  Dynamic cavernosometry was considered the gold standard during this comparative study. The sensitivity of duplex ultrasonography was found to be 100%, its specificity was 71.42%, positive predictive value 80% and its negative predictive value was 100% in the detection of caverno-venous incompetence.
